Chapter 2: Scales
Scale degrees
· 1st – tonic
· 2nd – supertonic
· 3rd – mediant
· 4th – subdominant
· 5th – dominant
· 6th – submediant
· 7th – leading tone (half step below tonic)
· 7th - subtonic (whole step below tonic as in natural minor scale)
Major Scale
· 8 notes, including the octave
· half step between 3-4 and 7-8
· comprised of 2 tetrachords separated by a whole step
· tetrachord pattern: whole – whole – half
Transposition
· Major or minor scale pattern repeated at any pitch
Key signature
· Order of sharps: F-C-G-D-A-E-B
· Order of flats: B-E-A-D-G-C-F
· Determining key:
o Up one half step from last sharp
o Down to the next-to-the-last flat
Relative minor
· minor third or three half steps below major scale
· (C Major and a minor)
Parallel minor
· same tonic but different key signature
· (C Major and C minor)
Minor scales
· Natural minor – same notes as its relative Major
· Harmonic minor – raised 7th both ascending and descending
· Melodic minor – raised 6th and 7th ascending (sounds major) and lowered descending
Pentatonic scale
· 5-tone scale
Chromatic
· 12 notes (13 including the octave)
· Uses only half steps
· Each tone is equidistance from the next so it has no tonic
Whole-tone
· 6-tone scale made up only of whole steps (7 including the octave)
Blues scale
· Flat 3rd and flat 7th
Octatonic (or diminished) scale
· Alternates whole and half steps
· Jazz musicians refer to it as diminished because the chords resulting from the pitches are diminished
Church modes
· I - ionian
· Don’t - dorian
· Play - phrygian
· Loud - lydian
· Music - mixolydian
