24 - 30
take AP music theory instead bc the resource guide sucks
key - set of 7 notes, or scale, selected for a piece
key signature - sharps of flats at start of staff, indicate key
of music
E scale needs raised 2nd note (F) to become natural minor
G scale needs raised 7th note (F) to become major scale
all 3 types of minors use the same key signature, harmonic
and melodic use accidentals to individual notes
key signature is for convenience
C and Eb are relative minor-major scales
30 possible keys (y'all ugly for that)
15 major, 15 minor (once again, y'all ugly)
perfect fifth - 7 half steps
3 pairs of scales overlap:
B/Cb - 5 sharps/7 flats
F#/Gb - 6 sharps/6 flats
C#/Db - 7 sharps/5 flats
order of sharps: F C G D A E B
fat cats go down alleys eating burgers
order of flats: B E A D G C F
bead gcf (greatest common factor)
reverse order
minor circle of fifths: A minor scale at top

Harmonic Progression
╙═══════☆═══════╜
harmonic progression - series of chords or intervals that
move from tension (dissonance) to resolution (consonance)
dissonance - quality of pitch, interval, or chord that seems
unstable or tense
opposite of dissonance if consonance
Alfred Hitchcock's Psycho - score by Bernard Hermann
most consonant chords stress lower partials of overtone series
major triad with double root is very consonant
chords sound consonant or dissonant depending on preceding
chord
tritone (TT) 3 whole steps, 6 half steps
augmented fourth/diminished fifth depend on spelling of notes
diatonic - within the key
quality - major, minor, diminished, augmented, depend on scale
degree
chromatic - borrow notes from outside of key
tonic triad - built on scale degree 1, most stable
most pieces end on tonic
other major triads in a key: scale degree 4 and 5
minor triads in key: 2, 3, 6 (USAD made a whole typo smh)
diminished triad: 7, highly unstable
capital roman numeral: major
lower case: minor
lower case with degree sign: diminished
dominant chord (V) most important
had leading tone and 5
pre dominant harmonies - pull to V
triads built on 2 (supertonic) and 4 (subdominant) most common
chord progression - chain of triads, each pulling to next one
voice leading - inverted chords make it easier to sing
bass line - lower voice, in bass clef, usually has root
cadances - pausing points/end of piece
most final sounding bass line goes from 5-1, melody end on 1
dominant seventh - add minor 7th from root of chord
scale degrees 5-7-2-4
dominant seventh - contains tritone between 7-4
7 pull to 1, 4 pull to 3
