Key Signatures/ Intervals
Week 4
Learning Outcomes
• By the end of today’s session, students will be able to:– Understand the practical use of key signatures– Develop a method for identifying and constructing
major key key signatures– Develop a method for identify and constructing
natural/relative minor key key signatures
Scales Review
• What is a scale?• What interval pattern characterizes a Major
scale?• What interval pattern characterizes a Natural
Minor scale?
• Key signatures put the required accidentals for various scales at the beginning of a piece of music
• They are placed directly to the right of the cleff, just before the time signature.
Which notes in this piece will be flattened?
Why Key Signatures
• Easier to read music• With the accidentals of the key signature at
the beginning, the key is recognizable immediately, even if there is a lot of chromatic alterations afterwards.
Placement
• The placement of the accidentals in a key signature follows a rigid pattern.
• This sequence is the result of the circle of 5ths• Each successive note name is a 5th above or
below the preceding pitch. • To be logically sequenced, the building of key
signatures follows a cycle
Flats
• Battle Ends And Down Goes Charles’ Father• See Example 2 on page 13
B♭E♭ A♭ D♭ G♭ C♭ F♭
Sharps
• Father Charles Goes Down And Ends Battle• See Example 1 on page 14
F♯C ♯ G ♯ D ♯ A ♯ E ♯ B♯
Placement
• In order to be immediately recognizable, key signatures must always be placed in this exact order on the staff
• See Example 2 on page 14
Recognizing Key Signatures
• Know the number of sharps and flats used• For flat keys the major key is represented by
the flat before the last flat• For sharp keys, the major key is a half step
above the last sharp
Relative Minor
• Each major key signature has a relative natural minor which uses the same set of notes
• The relative minor for each is the 6th scale degree of the major scale
• Eg. C D E F G A B C• What is the relative minor to F major?• F G A Bb C D E F
