INTRODUCTION
The aim of the Counterpoint and Fugue textbook is to introduce concepts and
terminology pertaining to polyphony, and to help students develop their music
analysis abilities. Baroque instrumental and vocal music displays a wealth of
contrapuntal devices, which will represent the focus of this analytical endeavour.
Students will be familiarized with various compositional techniques and stylistic
features as well. The subject requires prior solid knowledge of music theory and tonal
harmony.
EVALUATION
Students will be tested in writing at the end of each semester, as well as
periodically throughout the year. Homework and in-class practice will comprise of
identification of various techniques, as well as contrapuntal writing exercises.

1. BAROQUE COUNTERPOINT
1.1 The Baroque Musical Style
The Baroque era saw the emergence of functional tonality, and of tonal harmony, as its essential attribute. Functional harmony involves a precise hierarchy
among chords / harmonic degrees, and a preference for certain types of harmonic
progressions, which is equally taken into account in polyphonic contexts. The tonal
system is thus organized around the Major-minor scales, the functional identities of
Tonic, Dominant, Subdominant, and the various relationships that are established
among key centres (relative keys, near-related keys, parallel keys, etc.). The concept
of harmonic cadence represents a reference point in polyphonic music.
Tonality is a complex system, a paradigmatic way of pitch structuring, which
evolved in close relationship with other musical phenomena, such as rhythm, metre
and form. Baroque polyphony showcases all the traits that are typical of the tonal
system.
1.2 Baroque Melodic Features
Baroque melodic lines are intimately related to the harmonic background of
the specific musical context in which they unfold. Sometimes, harmonic content
generates the melodic contour itself. The two principal melodic types are:
- Melodic lines with explicit harmonic content;
- Melodic lines with apparent harmonic content.
The first type includes lines that contain figurations, arpeggiandos – primarily
instrumental in nature. The second type includes lines that originate in Gregorian
7
Counterpoint and Fugue Tudor Feraru
chant, or Lutheran chorale phrases – primarily vocal in nature. Stepwise motion is
very common, either directly or ornamentally.
Chromaticism is frequently encountered. In the works of Johann Sebastian
Bach, chromaticism has a few distinct functions:
- Ornamental chromaticism;
- Modulatory chromaticism;
- Passus duriusculus (chromatic tetrachord / pentachord, usually descending).
1.2.1 Intervallic Idioms
Baroque melodic lines enjoy relative freedom with respect to the intervals
used; however, lines are organically constructed, by means of unique motives, cells
and figurations.
Characteristic intervals are the augmented fourth, the diminished fifth, and the
diminished seventh (more rarely, the augmented second as a substitute). Rising,
falling or undulating scale patterns are common, as are changes of register within the
same melodic line.
Among the various means for melodic development are repetition,
transposition, sequencing, intervallic variation, fragmentation, changing harmonic
content, apparent polyphony, etc.
1.2.2 Rhythm of Polyphonic Writing
Rhythm of Baroque polyphony displays consistency (with regard to particular
features and patterns) and fluency. The rhythmical continuum may be achieved by
individual voices, or by complementarity among voices.
The following patterns are typical of Baroque contrapuntal writing:
- Syncopated rhythms;
- Repeated patterns (dactyl, anapest, iamb, trochee, triplet, dotted rhythm,
Sicilian rhythm, etc.);
8
Counterpoint and Fugue Tudor Feraru
- Mixed rhythm (virtually free combination of various patterns).
As far as metre is concerned, melodic lines may begin on downbeats, on
upbeats, or within incomplete measure (catalectic). Melodic hemiolas (rhythmic
patterns of syncopated beats, with two beats in the time of three or three beats in the
time of two) are relatively frequent, especially in the music of J.S. Bach.
1.2.3 Harmonic Content of Melodic Lines
Harmonic content refers to the actual harmonies / chords that could be
extracted from polyphonic music. The Baroque style is characterized by strict
periodicity of harmonic progression. Once established, the harmonic rhythm remains
constant over extended segments of music. Melodic lines frequently imply harmonic
content, through intervallic contour, arpeggiation, ornamentation, etc.
1.3 Apparent Polyphony
Apparent polyphony represents the illusion of two (or multiple) voices created
by a single voice. The impression of virtual additional melodic layers may result in
one of the following situations:
- A pivot note + a set of moving notes (usually stepwise motion);
- Two distinct, alternating sets of moving notes (or alternating pivot notes);
- An embellished pivot note + a set of moving notes;
- A melodic cell that replicates in significantly spaced-out registers, giving the
impression of multiple voice entries;
- Two contrasting, alternating, melodic cells or figures (usually in different
registers, as well).
9
Counterpoint and Fugue Tudor Feraru
By means of apparent polyphony, a single voice (usually instrumental in
nature) generates clearer harmonic content, without the need for actual multiple voice
superimposition.
1.4 Techniques of Melodic / Rhythmic Development
1.4.1 Inversion. Retrograde Form. Retrograde Inversion
For purposes of melodic and motivic variation, Baroque music places great
emphasis on several melodic development procedures, such as melodic inversion,
retrograde melodic form, and retrograde inversion.
Inversion consists of reading successive intervals of a melodic segment in the
opposite direction (e.g. a rising third becomes a falling third). Only the quantitative
aspect of intervals is preserved. Melodic inversion may be rigorous or free.
Retrograde form involves reading an already stated melodic segment right-to-
left. This procedure affects rhythmic patterns as well, and sometimes renders the
melody impossible to recognize. For this reason, retrograde form is utilized much less
frequently.
Retrograde inversion combines the two techniques – thus, a line is stated from
its end to its beginning, with each melodic interval going in the opposite direction
compared to the original.
1.4.2 Augmentation. Diminution
Augmentation represents the lengthening of all note values in a melodic part,
by the same rate (doubling, tripling, quadrupling durations).
Diminution is a similar process, consisting in shortening of all note values
(usually halving durations).
10
Counterpoint and Fugue Tudor Feraru
Thus, recurrences of a melodic segment may preserve the initial rhythmic
durations, or have proportionally increased / decreased durations. The melodic
intervals are generally not affected by such a procedure.
1.5 Baroque Two-Part Writing
Two-part polyphony entails a set of norms that govern the relationship
between the two voices, and most of the time generates explicit harmonic content.
In the Baroque style, all harmonic intervals are utilized, with certain
preferences with regard to the strong beat - weak beat relationship, as described
below.
Excepting the initial statement of melodic material, and endings of significant
fragments, all unisons, perfect octaves and perfect fifths are avoided. Therefore,
strong beats prefer the harmonic intervals of thirds, sixths, tenths, or dissonances.
1.5.1 Dissonances in Two-Part Polyphony
In Baroque counterpoint, the concept of dissonance refers to a note that meets
two distinct criteria simultaneously:
- It is a note foreign to the existing harmonic content (a non-harmonic tone);
- It is a note that generates a harmonic interval of a second, seventh, fourth,
ninth or eleventh in combination with the other voice; these intervals are considered
dissonant in the Baroque style.
Whenever either of the two criteria is not met, the respective note is deemed a
semi-dissonance (e.g. the note generating a seventh, as part of a virtual dominant
seventh-chord, or a non-chord tone that creates a sixth in combination with the other
voice).
11
Counterpoint and Fugue Tudor Feraru
Baroque counterpoint is characterized by optimal balance between the amount
of consonance and dissonance. In the case of J.S. Bach’s music, an abundance of
dissonances is typical and expressive, while the harmonic content remains functional.
In music analysis, dissonances will be marked with an x, and semi-dissonances with
an (x).
Types of dissonances:
Passing tone – in terms of melodic contour, it may be ascending or
descending, with any duration, on any beat or part of beat – including relatively strong
beats. The following are a few possible passing tone situations:
1) Passing tone + sustained note in the other voice;
2) Passing tone + octave leap;
3) Passing tone + movement between chord members;
4) Passing tone + arpeggiation;
accented passing tones accented passing tones
5) Passing tones in both voices, in contrary stepwise motion, either with identical
or with different rhythms;
6) Passing tones in both voices, in direct / parallel stepwise motion, usually with
different rhythms;
NOTE: Cases 5) and 6) allow two situations – either beginning and arriving on a
vertical consonance, or simply arriving on a consonance (irrespective of the number
of dissonances along the way):
12
Counterpoint and Fugue Tudor Feraru
7) Passing tone with change of register;
8) Passing tone approached or continued by a skip / leap.
Neighbouring tone – in terms of melodic contour, it may be superior or
inferior, with any duration, on any beat or part of beat – including relatively strong
beats. The following are a few possible neighbouring tone situations:
1) Neighbouring tone + sustained note in the other voice;
2) Neighbouring tone + octave leap;
3) Neighbouring tone + movement between chord members;
4) Neighbouring tone + arpeggiation;
5) Neighbouring tone + stepwise motion (in combination with passing tones);
6) Neighbouring tone + arpeggiation and stepwise motion;
13
Counterpoint and Fugue Tudor Feraru
7) Dual neighbouring tones (simultaneous or slightly delayed).
NOTE: Sometimes, two simultaneous neighbouring tones, in contrary motion,
may generate the harmonic interval of a diminished octave (dissalteration).
8) Neighbouring tone approached or / and continued by a skip / leap (called
escape tone).
Anticipation – is a non-accented, dissonant, non-chord tone that becomes a
chord member on the immediately following beat. It may be falling or rising, and
always involves note repetition (or syncopation). Anticipations may be approached by
step or by skip / leap. They are commonly associated with dotted rhythms and
cadential gestures:
14
Counterpoint and Fugue Tudor Feraru
falling anticipation rising anticipation anticipation approached by leap
The passing tone, neighbouring tone and anticipation are collectively referred
to as ornamental dissonances.
Suspension / Retardation – is a dissonant note that is approached from and
resolved to a consonance, by a falling or a rising step (either whole-tone or half-tone).
Suspensions are evident dissonances that occur on strong beats or parts of beats. Any
chord member may be delayed by means of a suspension, and any of the polyphonic
voices may contain suspensions / retardations. Suspensions may be prepared – by the
same note, in the same voice, that is usually a consonance in the context of the
preceding harmony. Preparation involves either note repetition or a tie.
NOTE: The preparation itself may be a dissonant note – such a situation is called a
self-prepared dissonance.
Sometimes, the suspension is not followed directly by its resolution, but rather
by a foreign note, or a group of foreign notes that precede the consonant resolution.
Such a case represents an ornamentally resolved suspension (figured resolution). The
interpolated foreign note(s) will be called the suspension’s figuration.
Possible situations of ordinary suspension:
1) Suspension + sustained note in the other voice;
2) Suspension + octave leap;
3) Suspension + arpeggiation;
4) Suspension + ornamental dissonances;
5) Suspension + ornamental dissonances at the time of resolution;
6) Suspension + combination of stepwise and arpeggiated motion.
15
Counterpoint and Fugue Tudor Feraru
The following are some of the possible cases of ornamentally resolved
(figured) suspensions (all situations listed for ordinary suspensions are relevant, too):
1) Figuration by dissonance repetition;
2) Figuration by interpolation of a consonant note (by leap);
3) Figuration by interpolation of a note group in stepwise motion;
4) Figuration by interpolation of an arpeggio;
5) Figuration by interpolation of both arpeggiated and stepwise motion;
6) Retardation that resolves in a different voice;
7) Retardation that eludes resolution altogether (or continues to another
dissonance, rather than a consonance).
usually consonant
16
Counterpoint and Fugue Tudor Feraru
NOTE: A suspension / retardation that lacks preparation is also named
appoggiatura. In the case of figured suspensions, the figuration itself may include one
or more appoggiaturas.
1.6 Harmonic Sequence in Contrapuntal Context
Harmonic sequence is the direct recurrence of a musical idea, on a different
pitch level. It consists of an immediate, transposed, strict or free repetition of a
melodic segment and its supporting harmonies. The repetition may occur once or
more times. The starting point of each sequence is called a model (pattern), while the
transposed recurrences represent the sequences proper.
Harmonic sequence can be:
- Strict or free;
- Tonally stable (usually diatonic, but chromatic sequencing is to a
certain degree possible), or modulatory;
- Ascending or descending;
- Authentic or plagal;
17
Counterpoint and Fugue Tudor Feraru
- Stepwise or non-stepwise (involving skips from one recurrence to
another).
The Baroque style utilizes mostly strict, authentic sequencing.
1.6.1 Sequencing Patterns
Descending stepwise sequencing conforms to the following possible patterns:
- The “circle of fifths” pattern (chord roots move by intervals 5↓-5↓, 4↑-4↑, or
4↑-5↓):
//
- The 3↓-2↑ pattern:
18
Counterpoint and Fugue Tudor Feraru
- The 2↑-3↓ pattern:
Ascending stepwise sequencing involves three possible patterns, as well. They
are classified according to the chord root movement:
- The 3↓-4↑ pattern;
- The 4↑-3↓ pattern;
- The 2↑ pattern – where the harmonic model contains only one chord.
Ascending sequencing is less typical of the Baroque style.
Harmonic sequence may be modulatory or non-modulatory. When modulation
is involved, the target key is usually that of the dominant or relative. It is possible to
encounter continually modulatory sequences (especially following the circle of fifths
pattern).
Sequencing, as a melodic / harmonic development device, is characteristic to
the entire Baroque repertoire. In the music of J.S. Bach, the process consists of two to
three sequences the most, in order to prevent it from becoming cliché.
Free (non-rigorous) sequence may involve changes in the sequencing interval,
the sequencing direction, or the harmonic model.
1.7 Two-Part Invertible Counterpoint / Double Counterpoint
Invertible counterpoint is a technique of writing two (or more) voices so that
their registral positions can be reversed. Thus, the higher voice can become the lower
and vice versa, while conforming to conventions of dissonance treatment. Sometimes,
the technique is called “double” counterpoint because each of the two voices serves a
19
Counterpoint and Fugue Tudor Feraru
dual role, either as upper or as lower part. The procedure was known during the vocal
polyphony era; however, it became prevalent only in the Baroque style.
A B
B A
Invertible counterpoint involves three main possibilities, with regard to the
permutation interval: at the octave (most frequent), at the tenth, and at the twelfth.
In the familiar case of inversion at the 8ve, where one of the two voices is
transferred above or below the other voice by transposing it up or down an octave, a
third inverts into a sixth, unison into an octave, second into a seventh, augmented
fourth into a diminished fifth. In those cases, consonance inverts into consonance,
dissonance into dissonance. However, the interval of fifth inverts into a fourth, which
is a dissonance in two-voice counterpoint. Fifths in two-voice invertible counterpoint
must therefore be written as though they were dissonances.
Invertible counterpoint at the 12th and at the 10th is much less common, due
to the technical difficulties and the harmonic transformations it would involve. For
example, in the infrequent case of invertible counterpoint at the 10th, parallel thirds
and sixths need to be avoided, because they would result in parallel octaves and fifths,
respectively.
The principle of inverting voices is not affected by actual transposition of the
entire polyphonic structure on a different pitch level.
The concept of rhythmic double counterpoint refers to a situation in which the
technique is not applied to the melodic intervals of the two voices, but rather to their
rhythmic makeup.
Sometimes, an entire polyphonic work is designed according to invertible
counterpoint principles; in such a case, the technique generates the form of the piece
itself. The double counterpoint relationship may be applied to individual musical
phrases, or be relevant to entire sections of the piece. The example below illustrates
the use of invertible counterpoint over entire phrases, along with a modulation to the
dominant key:

measures 6-7
1.8 Baroque Three-Part Writing
Three-part counterpoint is characterized by the existence of explicit harmonic
content, resulting from functional chord progressions. The consonance-dissonance
relationships follow the same norms as in the case of two-part writing.
In the case of three-part polyphony, chord doublings are treated more freely
than in conventional harmony; in principle, any chord member may be doubled, as
long as voice-leading is correct. From the superimposition of three distinct lines, the
possible resulting vertical structures are as follows: complete triads, incomplete triads
involving doublings, incomplete seventh-chords, as well as multiple unisons.
1.8.1 Dissonances in Three-Part Polyphony
The dissonance types are the same as in two-part polyphony: passing tone,
neighbouring tone, anticipation, suspension (or appoggiatura), and various
combinations of these.
21
Counterpoint and Fugue Tudor Feraru
Passing tone – may occur in all forms already described. The following
situations are typical of three-part counterpoint:
dual passing tones, by parallel or contrary motion:
single and dual passing tones, by parallel or contrary motion (in context):
triple passing tones, in identical rhythm, by contrary motion:
passing tone approached by leap:
22
Counterpoint and Fugue Tudor Feraru
Neighbouring tone – may occur in all forms already described. The following
situations are typical of three-part counterpoint:
dual neighbouring tones, by parallel or contrary motion:
neighbouring tone chromatic approached by leap: neighbouring tones:
Anticipation – may occur in all forms already described. A few particular
cases are the dual anticipation (with both voices approached by step, with one by step
and the other one by leap, or both by leap), and anticipation followed by a suspension:
single anticipation: dual anticipations (by step and by leap, followed by suspensions):
Suspensions / retardations (appoggiaturas) occurring in three-part polyphony
are even more evident dissonances, due to the explicit harmonic content. They may be
assigned to any of the voices, and behave much like their two-voice counterparts.
23
Counterpoint and Fugue Tudor Feraru
Thus, dual suspensions / retardations, various figuration patterns, atypical resolutions,
as well as combinations with other ornamental dissonances are possible. The
following situations are typical of three-part counterpoint:
dual suspensions, dual suspensions, dual suspensions dual suspensions identical rhythm: different rhythm: + other dissonances: with figuration:
1.9 Three-Part Invertible Counterpoint / Triple Counterpoint
Triple counterpoint, similarly to double counterpoint, is a technique of writing
three voices so that their registral positions can be exchanged. There are six
permutation options, of which usually three or four are utilized (some permutations
raise harmonic problems, related to consonance-dissonance conventions, or produce
incorrect six-four chords).
A B C A
B A B C
C C A B
The most frequently used type of triple counterpoint is at the octave. Invertible
counterpoint in three or more parts is easier to achieve when there is an abundance of
dissonances.
In order to avoid six-four chords, fragment beginnings and endings will have
to contain incomplete chords (omitting the fifths). Al precautions with regard to voice
leading that were mentioned in the case of double counterpoint apply here too.
24
Counterpoint and Fugue Tudor Feraru
There are particular cases of triple counterpoint, in which the permutation
process is applied only to two of the three voices, while the third retains its constant
registral position (usually, the bass line).
Invertible counterpoint (double, triple or multiple) is essentially a musical
development device, which allows for increased exploitation of melodic material. The
technique is used extensively in J.S. Bach’s Fugues (in Fugues with Countersubjects,
or Fugues with more than one Subject).1
1.10 Baroque Polyphonic Techniques
1.10.1 Imitation – General Principles
Imitation is the identical or slightly modified restatement of a melodic
segment, in a different voice of the polyphonic texture. Exact repetition is called strict
(rigorous) imitation, while modified repetition is called free imitation.
Imitation may begin on the same pitch level, or on a different pitch than the
original material. In Baroque polyphony, the imitation interval is variable (most
common are the unison, perfect octave, perfect fifth or fourth, either up or down).
The original melodic segment may be followed by its imitation immediately,
or after a short transition material. It is also possible to have a closely followed
imitation (involving partial superimposition of the original with its imitating material).
Such a case is called stretto. This is usually realized by successive melodic entries, a
measure or less apart. The stretto technique may involve two or more voices entering
in cascading imitations.
Imitations may preserve the original rhythm, or may occur with proportionally
lengthened or shortened durations (in augmentation or diminution, respectively).
Successive melodic intervals of the original melody usually remain
unchanged. However, in the case of imitation at common intervals (perfect fifth and
1 See Chapter 2, dedicated to the Fugue.
25
Counterpoint and Fugue Tudor Feraru
perfect fourth), it is possible to encounter changes in the intervallic makeup (strict
versus free imitation). Such changes will be described in detail later on.
1.10.2 Canon. Canonic Imitation
Canonic imitation is the very strict imitation of an extended melodic segment,
occurring in two-part, three-part, or multiple-part counterpoint. The consecutive
imitating entries are usually close together.
A musical work based exclusively on this technique is called a canon. Canons
may include imitations at different intervals, augmentations, diminutions, as well as
inverse or retrograde forms of the melodic material. When the melodic material of
each voice arriving at its end loops back to its beginning, the piece becomes a round,
or perpetual canon.
More rarely encountered cases are those of the double canon – a multi-voice
composition that unfolds two different canons simultaneously, and the mirror canon –
in which voices imitate one another in inversion, by contrary motion.
Writing a canon involves step-by-step imitation, so that each segment of the
leader is repeated rigorously and immediately by the follower, while each new
melodic segment becomes the very counterpoint to its preceding segment. Masterful
examples of canons can be found throughout the works of J.S. Bach, such as in his
Musical Offering.
1.10.3 Ground Bass Technique (Basso ostinato)
Basso ostinato is a contrapuntal technique in which a short, recurring melodic
pattern (usually in the bass part) serves as the principal structural element. The pattern
is concise and emblematic, and is repeated identically or slightly modified throughout
the entire musical work.
In addition to the ground bass, a variable number of contrapuntal voices
contribute to a freely, yet organically, polyphonic unfolding. The technique generally
26
Counterpoint and Fugue Tudor Feraru
involves evolution from simple to complex textures (with regard to rhythmic
intricacy, harmonic content, registral spacing, etc.). Musical works based chiefly on
the ground bass technique are the Passacaglia and the Ciaccona. In J.S. Bach’s
output, the best-known examples are his Passacaglia for organ in C minor, and
Ciaccona for solo violin in D minor.
The ostinato pattern may migrate to other parts, including the discant. It may
also be subjected to transformations, variations (ornamentation, rhythmic alteration,
fragmentation, etc.). The number of contrapuntal voices varies from section to section.
The ostinato technique is sometimes combined with imitation and its various forms.
A universally valid distinction between Ciaccona and Passacaglia is
impossible to operate. In J.S. Bach’s case, Passacaglia involves changes to the
harmonic background from one recurrence of the pattern to another, while Ciaccona
preserves the same harmonic background throughout.
1.10.4 Complementary Voice Motion Technique
This technique derives its basic principles from the concept of complementary
rhythm. Complementary rhythm refers to a situation in which two or more voices
achieve continuous motion by complementing each other’s pulse. Complementary
voice motion usually opposes a significant melodic line to one or more supporting
contrapuntal parts, which then reverse roles. The supporting parts may contain
sustained notes, repeated rhythmic patterns, or various combinations of these. They
can themselves move in- or out- of sync. Such an approach insures textural interest,
while highlighting each of the polyphonic voices.
1.10.5 Parallel Counterpoint Technique (Planing)
Parallel voice-leading (German: Mixturen) is a technique in which a leading
voice is shadowed by one or more supporting, secondary lines that move by parallel
27
Counterpoint and Fugue Tudor Feraru
intervals (usually parallel thirds, sixths, or six-chords). Most frequently, the main line
and its parallel melodies have the same rhythmic structure.
The technique is sometimes called planing. The role of the supporting lines is
to emphasize melodic contour. They may also move by contrary or oscillating motion,
producing densely textured polyphony. This phenomenon is more frequently
encountered in instrumental or vocal-instrumental contexts (e.g. the orchestral
introduction to Saint Matthew’s Passion, or Sanctus from the Great Mass in B minor,
both by J.S. Bach).
1.11 Settings of Chorale Melody. Chorale Variations
Protestant chorale tunes made their way into Baroque art music in various
forms and contexts, from simple four-voice harmonizations, to sophisticated
polyphonic works (organ pieces, cantatas, etc.). J.S. Bach exploited the chorale
repertoire extensively, in a few distinct types of settings / arrangements.
Chorale variations are a species of polyphonic compositions based on the
contrapuntal treatment of chorale melodies, usually involving two to five voices. The
characteristic features of such arrangements are complementary rhythm (with constant
duration ratio of 1:2, 1:3, 1:4, 1:6, 1:8), and independence of lines. Ostinato patterns
are sometimes utilized. In other cases, contrapuntal lines are highly complex, to the
point they overshadow the chorale melody itself.
Chorale melodies are usually assigned to the highest voice, but they can
appear in any of the other voices, as well. They may be arranged ad literam, with
proportionally lengthened durations, or in a fragmentary manner (with individual
phrases spaced out by interludes), or even in ornamental forms (from elementary to
very rich ornamentation).
Contrapuntal lines may involve imitation (even canonic imitation), and various
melodic development techniques (augmentation, diminution, inverse or retrograde
forms). Monumental chorale variations incorporate full-scale preludes, interludes and
postludes alternating with the actual chorale phrases.
28
Counterpoint and Fugue Tudor Feraru
NOTE: Chorale variations of the Baroque period should not be mistaken for
variation forms (theme and variations), or for Fugues with Subjects derived from
chorale melodies!
1.11.1 Chorale Partitas
A chorale variation may be continued with other polyphonic settings of the
same chorale tune. Such a multi-movement composition based on the same chorale is
called a chorale partita. It is usually written for a keyboard instrument (mainly
organ). Chorale partitas share similar traits with conventional variation cycles, as
stipulated by musical forms.
Sometimes, contrapuntal techniques utilized in chorale variations and chorale
partitas infiltrate other polyphonic genres. Chorale arrangements that incorporate
ample preludes, interludes, postludes, and sophisticated polyphony render the chorale
melody itself a mere pretext for a monumental composition.
1.12 Subject - Answer Relationship
Polyphony may be divided into two main categories: imitative and non-
imitative. In imitative polyphony, the two main members of the polyphonic texture –
the original and its imitation – are commonly called Subject and Answer (Dux and
Comes in Latin, or Leader and Follower in English). A number of correspondences
are established between the Subject and its Answer(s), generally depending on their
degree of similarity.
29
Counterpoint and Fugue Tudor Feraru
1.12.1 Real Answer
Real Answer results from an imitation with no modifications except for the
diatonic adjustment of half and whole steps. It may represent an exact transposition of
the original material to a different pitch level.
1.12.2 Tonal Answer
There are situations in which, for tonal stability reasons, the Answer is
subjected to slight intervallic changes. Such a case is called Tonal Answer. A Tonal
Answer is usually called for when the Subject contains a prominent dominant note
very close to its beginning, and prevents the undermining of the sense of key. The
usual perfect fifth or perfect fourth relationship between the initial pitches of the
Subject and Answer place the music in a Tonic key - Dominant key paradigm. The
very role of the Tonal Answer is to prevent the music from migrating to other key
centres (such as the Subdominant, for example).
1.12.3 Cases of Tonal Answer Use
A Tonal Answer closely resembles its Subject, but does not replicate it
exactly. Here is a classification of such cases:
1) When the Subject begins with scale degrees 1-5 – the Answer will begin
with scale degrees 5-1, or vice versa;
NOTE: If 1-5 or 5-1 is the predominant interval, elementary ornamentation will
not affect the need for a Tonal Answer.
2) When the Subject begins on scale degree 5 (regardless of what the next degree
is) – the Answer will begin on scale degree 1, and one of the initial melodic
intervals will be modified;
30

3) When the head of the Subject contains the 1-7 or 7-1 scale degrees – the
Answer may be Tonal or Real, depending on each particular situation;
NOTE: In the first three cases, intervallic changes always occur at the beginning
of the Answer.
4) When the Subject modulates (usually to the Dominant key) – the Answer will
either avoid further modulation, or will re-modulate to the Tonic key; in this
case, intervallic changes will occur toward the end of the Answer (in very rare
cases, a modulating Subject is followed by a Real Answer – an Answer
beginning in the Subdominant key is normally employed for this reason);
5) This case is a combination between one of the first three cases and case
number 4; therefore, two modifications will be necessary – one at the
beginning and one at the end of the Answer (such a situation is commonly, yet
improperly, called a “Double-Tonal” Answer).
NOTE: In certain (yet rare) situations, J.S. Bach employs Real Answers to
Subjects that would normally call for Tonal Answers.

2. FUGUE (In the Music of Johann Sebastian Bach)
2.1 Fugue – General Presentation
The Fugue is a type of polyphonic composition (a musical genre), and
represents at the same time a structural model, and a contrapuntal technique that was
perfected during the Baroque era. Its origins are complex and are rooted in several
genres of the past, such as:
- The vocal Motet, and later the instrumental Ricercar (in terms of the imitative
technique);
- Toccatas of the early Baroque, as well as improvisatory Fantasias and
Capriccios (in terms of instrumental / keyboard style writing).
From a contrapuntal point of view, the Fugue is built on successive imitative
statements of a prominent melodic material, called Subject. The imitative entries,
called Answers, usually occur at intervals of perfect fifths or fourths. A tonal
exposition centered on the Tonic and Dominant keys is followed by additional
restatements, in other keys. These “thematic” statements may alternate with sections
of non-thematic material.
Structurally, a Fugue is made up of an Exposition, a Development section
alternating Middle Entries and Episodes, and a Final Entry (possibly a Coda, as well).
Baroque Fugues display highly individualized thematic material, which is
subsequently imitated, developed, transposed, etc. The tonal itinerary is also of
paramount importance, with the Subject centering on the Tonic, and the first Answer
on the Dominant. A modulating Subject will call for a re-modulating Answer, or for a
transition segment that returns to the home key prior to the beginning of the Answer.
33
Counterpoint and Fugue Tudor Feraru
2.2 The Fugue Subject – Typical Features
It is important to note that the Fugue’s theme includes all statements of both
the Subject and the Answer.
Fugue Subjects may be categorized as follows (in accordance to their origin
and melodic nature):
- Subject type derived from Gregorian chant (e.g. WTC2 I / C#m);
- Subject type derived from Protestant chorale tunes (e.g. WTC I / F#);
- Subject type derived from instrumental technique (e.g. WTC II / G).
Subjects usually begin with scale degree 1, 5, or 3 (more rarely, with scale
degree 2 – WTC II / Bb, or scale degree 7 – WTC II / F#). Baroque Fugues
(especially those written by J.S. Bach) are based on particularly unique Subjects,
which feature certain melodic idioms. Some of these features derive from individual
motivic gestures, stepwise motion, figurations, the use of arpeggiation, of pivot notes,
of “wedging” melodic contour, etc. Subjects may also involve intense chromaticism,
or striking diatonic-chromatic oppositions.
The overall melodic span of a Subject may range from a third (as in the
unfinished B-A-C-H Fugue) to a ninth / tenth (as in WTC I / Bbm). Note repetition is
very frequent, especially at the beginning of the Subject (WTC II / D#m), but can also
occur toward the end (WTC II / Gm).
Apparent polyphony is common to longer Subjects, as is harmonic
sequencing. Fugues from The Well-Tempered Clavier contain small-scale sequencing,
while organ Fugues feature ample use of this technique.
As far as rhythm is concerned, Fugue Subjects are usually based on a few
distinctive patterns, such as:
- Constant / flowing rhythm (WTC I / Em);
- Constant rhythm interrupted by rests (organ Fugue in Dm);
- Ostinato / repeated rhythmic patterns (WTC I / Cm);
- Patterns derived from dance music (WTC II / Fm);
2 The Well-Tempered Clavier, Books I and II, by Johann Sebastian Bach
34
Counterpoint and Fugue Tudor Feraru
- Juxtaposition of contrasting patterns (WTC II / Dm);
- Relatively free rhythm / various pattern combinations (WTC II / Em).
The Answer is not always introduced immediately following the initial Subject
statement. A short melodic segment may separate the two initial entries – this is called
a codetta.
From a tonal point of view, there are stable (non-modulating) and modulating
Subjects. Therefore, the Answer itself may be stable or re-modulating. Codetta may
involve modulation or re-modulation, as well.
NOTE: A modulating Subject should not be mistaken for a tonally stable Subject
that is followed by a modulating codetta.
Fugue Subjects are quite diverse in terms of their internal structure. The
following are a few possible cases of Subject makeup:
- Indivisible melodic segment (WTC I / Ab);
- Individual opening gesture + melodic follow-up (WTC I / E);
- Two related melodic segments – by variation or sequencing (WTC II / G#m);
- Two contrasting melodic segments (WTC II / Bb, F, Eb);
- Sequenced opening + contrasting melodic material (WTC II / Gm);
- Three melodic segments – less frequent (organ Fugue in Cm);
- Fragmented structure / combination of various materials (WTC II / F#m).
2.3 The Fugue Exposition
The Fugue Exposition lasts from the initial note of the Subject to the final note
of the last thematic statement centered on the home or dominant key. Depending on
the number of constitutive voices, the Exposition may comprise of 2, 3, 4 or 5
successive entries (Baroque Fugues are typically written for three or four voices).
35
Counterpoint and Fugue Tudor Feraru
The first Answer may occur:
- Immediately following the Subject (WTC I / Em);
- After a short delay – which involves a connecting melodic material between
the end of the Subject and the beginning of the Answer (a codetta);
- Before the end of the Subject – which involves partial superimposition of the
two segments, in stretto (WTC I / A);
Codetta may contain material that is derived from the Subject itself (possibly
in the form of a sequence – WTC II / Em), or completely new material (WTC II / G).
2.4 Counterpoint and Countersubject
The melodic material that accompanies (in a different voice) a theme
statement (either Subject or Answer) falls into one of the following two categories:
- Free Counterpoint (FC) – when it is used incidentally as a companion for the
Fugue theme;
- Countersubject (CS) – when it accompanies all (or almost all) theme
statements (a constant companion for both the Subject and the Answer).
The Countersubject usually contrasts with the shape and character of the
Subject / Answer. The Countersubject / Free Counterpoint may begin at different
times, in relation to the initial Answer:
- At the same time as the Answer (WTC II / G#m);
- Later than the Answer – frequently (WTC II / Dm);
- Ahead of the Answer – rarely.
The Countersubject’s melodic material may derive from the Subject, from the
codetta, or may be completely new (providing contrasting elements).
36
Counterpoint and Fugue Tudor Feraru
Following statements of the theme in all constitutive voices of the Fugue,
additional entries are possible. This group of additional statements forms the Counter-
exposition. The Counter-exposition is sometimes separated from the Exposition by a
transition, and is in the same key as the original Exposition. The Counter-exposition is
then continued with the first Episode of the Fugue.
2.5 False Episode
The False Episode in a Fugue is a transition segment that separates two theme
statements within the Exposition. The most frequent placement for the False Episode
is between the first Answer and the following theme statement. It should never be
confused with a Codetta, which is merely a connecting melodic material at the end of
the Subject!
A False Episode may be placed:
- After two theme statements – in a 3-voice Fugue, with one remaining
statement following it;
- After two theme statements – in a 4-voice Fugue, with two remaining
statements following it;
- After three theme statements (rarely) – in 4-voice or 5-voice Fugues;
- In a Fugue with Counter-exposition, there may be even two False Episodes
(sometimes containing related material) – alternating with additional theme
entries; this case is typical to Fugues with modulating Subjects.
From a tonal perspective, False Episodes may be:
- Re-modulating (D ~ T), in the case of modulating Subjects;
- Non-modulating (T – T), in the case of modulating Subjects followed by re-
modulating Answers (a tonally stable False episode may, however, include
weak tonicizations).
37
Counterpoint and Fugue Tudor Feraru
A False Episode may be very concise or quite extensive (usually between one
measure and five measures long). Its melodic material may be derived from the
Subject, from the Countersubject (or Free Counterpoint), may be totally new
(contrasting), or may even be related to the Codetta – in which case it is called a
“Real” False Episode.
2.6 Episodes Proper
The Episodes in a Fugue are neutral segments that separate further entries of
the Subject / Answer. Episodic material is most of the time contrasting to the theme
and modulatory. An Episode has the primary role of transitioning for the next theme
entry in a new key. It also provides release from the strictness of the Fugue form.
Sequencing is very typical of Episodes, as is free counterpoint. More often than not,
Episodes feature variation in texture density, by temporary voice dropouts and
subsequent build-ups.
2.7 Middle Entries
The Middle Entries in Fugue are thematic segments outside the Exposition /
Counter-exposition. They are usually framed by Episodes. These segments may
contain a single statement of the Subject / Answer, or more (sometimes as many as six
statements). In Fugues from The Well-Tempered Clavier, Middle Entries are centered
on near-related keys, while in organ Fugues they can migrate to distant keys as well.
Regardless of the key in which a Middle Entry occurs, its theme statement is usually
rigorous.
Ricercar-type Fugues do not contain Episodes, and therefore they do not have
any Middle Entries per se. Such Fugues comprise solely of successive theme
statements, in a variety of keys, with no contrasting / episodic sections.
38
Counterpoint and Fugue Tudor Feraru
The size of a Middle Entry section depends on:
- The Subject’s length;
- The number of theme statements it contains;
- The amount of stretto it contains, and its degree of complexity.
Middle Entries may involve a change of mode (Major → minor or minor →
Major). Sometimes, the first Middle Entry in a Fugue does not follow after an
Episode, but rather immediately after the Exposition (or Counter-exposition),
evidently with statements in a key other than the Tonic or the Dominant.
Throughout the developing section of a Fugue, there may be “false entries” of
the theme, which include the head of the Subject / Answer, but are not given in full.
Such a procedure is usually associated with stretto. False entries often anticipate a
“true” entry of the Subject / Answer, heightening its impact.
2.8 Final Entry
The Final Entry in a Fugue represents the last theme statement (or group of
statements), in the home key. When the segment involves more statements, these may
center on the Tonic and Dominant keys. In the case of Fugues with a modulating
Subject, the last statement may begin in the Subdominant key, and eventually reach
the Tonic.
Sometimes, Final Entry segments contain a pedal point, which gives them a
more evident concluding character. At the end of the Final Entry segment, the
following situations are possible:
- A final cadence;
- A concluding extension, and then a final cadence;
- Additional entries, in stretto;
- A climactic conclusion, by means of parallel voicing (voice build-up);
- A rhetorical interruption / a fermata (frequently on a dominant, or an altered
chord), followed by a final cadence.
39
Counterpoint and Fugue Tudor Feraru
2.9 Coda
The closing section of a Fugue may include additional material that follows
the Final Entry. This is normally considered a Coda, and is cadential in nature. It is
usually made up of new material (sometimes related to the Subject’s counterpoint).
The Coda itself may involve a supporting pedal tone (“organ point”). The
conventional number of voices is sometimes amplified during the Coda (five, six or
more voices in the case of keyboard Fugues).
The final chord of a Fugue commonly contains multiple doublings. It can also
be incomplete (without a fifth, sometimes without a third, even multiple unisons of
the Tonic root). In the case of minor key Fugues, the final chord often introduces a
Picardy third (a major triad).
2.10 Development Techniques in a Fugue
Many Fugues utilize stretto as a polyphonic tool, sometimes right from the
Exposition. Stretto may occur during the Middle Entries, as well as in the closing
section of a Fugue.
Inversion of thematic material is also frequent, sometimes inside the
development section, or even generating an entirely separate, inverse Exposition (e.g.
in The Art of Fugue by J.S. Bach).
Fugue Subjects often appear in rhythmic augmentation or diminution.
Sometimes, two or more forms of the same thematic material are superimposed (e.g.
the original theme with its own augmentation).
Obviously, all these techniques may be combined, to create countless possible
development and variation situations.
40
Counterpoint and Fugue Tudor Feraru
2.11 Tonal Outline of Fugues
A Fugue’s Exposition and Counter-exposition always revolve around the
Tonic and Dominant keys. The Final Entry is also directed toward the Tonic / home
key.
The first notable key centre change occurs after the end of the Exposition, and
usually involves a modulation to the relative key, to the relative of the Dominant, or
even to the Dominant itself, which is consolidated this time.
Besides this typical tonal itinerary, there is no precise set of rules governing
the tonal outline of a Fugue. In the case of J.S. Bach, each individual Fugue reveals
unique features regarding its key relationships (especially in the developing section).
In monumental Fugues (like those written for the organ), modulations to distant keys
are not unusual.
2.12 Double and Triple Fugues
There are cases of Fugues that introduce two distinct melodic materials as
their theme. These are often presented simultaneously (or loosely simultaneously), in
contrapuntal relationship. Such a relationship is stronger and more egalitarian than a
simple Subject-Countersubject pairing, which works by subordination. Restatements
of the dual theme are normally treated in invertible counterpoint. Such a composition
is called a Double Fugue.
Similarly, a Fugue that interweaves three distinct melodic materials as its
theme is called a Triple Fugue (e.g. WTC I / Bb).
NOTE: A Double or a Triple Fugue should not be mistaken for a Fugue with two
or three Subjects, respectively. The distinction will be explained below.
41
Counterpoint and Fugue Tudor Feraru
2.13 Fugues with Two or Three Subjects
In rare cases, a Fugue may introduce, successively, two or even three distinct
Subjects. Each of these generates its own Exposition, usually followed by Episodes
and further theme entries. The closing section of such a Fugue consists of a synthesis
of previously stated thematic material – Final Entries that involve partial or total
superposition of the distinct Subjects / Answers. These superpositions may be also
treated in invertible counterpoint (an illustrative example of a Fugue with three
Subjects is WTC II / F#m).

3. EVOLUTION OF POLYPHONY FOLLOWING THE BAROQUE ERA
Polyphonic writing will be rather sporadic, and will see dramatic variation
from one composer to another during the musical eras following the Baroque.
Nevertheless, even in the context of primarily homophonic music, traces of polyphony
can be identified. The basic contrapuntal principles are the same as those found in the
works of J.S. Bach.
In the music of Haydn, Mozart, Beethoven, Mendelssohn, Schumann and
Brahms, for example, polyphonic textures are frequent, displaying a few particular
features, such as:
- First and foremost, all types of counterpoint utilized in the Baroque repertoire
are present; they are simply adapted to the new stylistic environment;
- The novelty factor is represented by the original mixture of homophony and
polyphony; contrapuntal techniques provide elements of contrast, and serve
development purposes;
- A new technique emerges, especially in instrumental / orchestral music:
textural polyphony (or layered polyphony), in which melodic lines are
absorbed into denser contrapuntal textures, and individual voices / parts are
grouped together to form distinct layers.
Some polyphonic stand-alone compositions, such as the Fugue, are
occasionally revived during the Classical and Romantic eras, with their basic structure
virtually unchanged, while being adapted harmonically and rhythmically to the new
musical style.
