TODAY:

COMPOUND METER:1 & uh, 2 & uh, 3 & uh, 4 & uh…Compound meter refers to any time signature or

meter in which each measure is divided into three or more parts, or two uneven parts, calling for the measures to be played with primary and secondary metric accents.

In Western music, the predominant form of compound meter is the division into three parts, often preferring to reduce a higher number of parts to written time signature changes, but more parts are possible.

3/8, 6/8, 9/8, 12/8, 6/4, 7/4, 7/8, 5/4, 5/8, etc. 6/8 time both simple and compound? What? “America” – West Side Story: Both 6/8 and 3/4

TRIADS:

A chord with 3 notes(A chord is a group of three or more notes played together)

Each note is a specific interval from the next

THREE NOTES - THE 1st NOTE:

ROOT=bottom note

THREE NOTES - THE 2nd NOTE:

THIRD=middle note

ROOT=bottom note

THREE NOTES - THE 3rd NOTE:

FIFTH=top note

THIRD=middle note

ROOT=Bottom note

THREE NOTES – NOTE POSITION:

WARNING! The root, third, and fifth will not ALWAYS be in that order!

FOUR TYPES OF TRIADS:

MajorMinorDiminished

Augmented

MAJOR TRIAD:

M3 + m3(P5)Created by taking the 1st, 3rd, and 5th notes of a major scale

MINOR TRIAD:

m3 + M3(P5)

DIMINSHED TRIAD:

m3 + m3(dim 5)

AUGMENTED TRIAD:

M3 + M3(aug 5)

SCALE DEGREE NAMES:TONIC (I/i)SUPERTONIC (II/ii)MEDIANT (III/iii)SUBDOMINANT (IV/iv)DOMINANT (V)SUBMEDIANT (VI/vi)LEADING TONE [SUBTONIC] (VII/vii)

V7 CHORD:Add a minor 7th to the root of a V triad (or a

minor 3rd above the 5th). The V7 chord is a chord and not a triad

because it has 4 notes rather than 3. Often, the 5th of a V7 chord is omitted. The

V7 chord then has the same number of tones as the I and IV chords while still retaining the quality of a 7th chord.
