Tonic
1st scale degree
Supertonic
The second scale degree, “above the tonic”
Mediant
The third scale degree, “halfway between tonic and dominant”
Subdominant
The 4th scale degree, “the 5th pitch below the tonic or the note below the dominant”
Dominant
The 5th scale degree, “the pitch dominating the tonality, a perfect fifth above the tonic”
Submediant
The 6th scale degree, “the note between the subdominant and the tonic”
Leading tone
The 7th scale degree, “leads upward toward resolution to the tonic”
Subtonic
The 7th scale degree in a natural minor scale, a note that is one whole steep below the tonic and is therefore not a leading tone
Blues scale
1 - flat 3 - 4 - flat 5 - 5 - flat 7 - 1
Pentatonic scale
Five note scale containing no half steps (C D E G A [C])
Whole tone scale
Seven note scale including the octave, each 1 whole step apart.1 - 2 - 3 - flat 5 - flat 6 - flat 7(C D E G flat A flat B flat C)
Diminished or octatonic scale
Scale distinguished with alternating half and whole step intervals
Natural minor scale
A scale with half steps between 2 and 3, and 5 and 6. It has a subtonic 7th scale degree.
Harmonic minor scale
A minor scale with half steps between 2 and 3 and 7 and 8.
Melodic minor scale

Major tetrachord
A chord consisting of the pattern W W H
Minor pentachord
W W H W W the same first five notes in all minor scales
Parallel minor
Major and minor related because they have the same tonic
Relative minor
Major and minor tonalities related because they share a key signature
Artificial scales
Scales that have altered notes
Resolution tones
Scale degrees 1 and 5
Ionian
A mode based on scale degree 1; the same as a major scale
Dorian
The scale based on the second scale degree in major; lowered 3rd and 7th
Phyrgian
A scale based on the 3rd scale degree in major; lowered 2nd, 6th and 7th; “angry” sounding
Lydian
A scale based on scale degree 4; major scale plus a sharp 4
Mixolydian
A scale based on the 5th scale degree; major scale plus a flat 7
Aeolian
A scale based on the 6th scale degree; a natural minor scale
Locrian
The scale based on the 7th scale degree; includes a diminished tonic triad, is a natural minor scale plus a flat 2 and a flat 5
Harmony
The way notes are simultaneously sounded creating a ventricle element to music
Counterpoint
A single line or voice added to another voice
Interval
Distance between two pitches
Melodic intervals
Sounding notes one after another (as in a melody)
Harmonic interval
Two pitches sounding at the same time (creating harmony)
Simple intervals
Intervals that are one octave or smaller in quantity
Compound intervals
Intervals that are larger than an octave in quantity
Rule of Nine
When inverting intervals, the sum of the ascending and descending intervals must add up to nine
Consonant intervals
P1, P5, P8, M3, m3, M6, m6, and sometimes P4. Melodically P4 is always a consonance.
Dissonant intervals
M2, m2, M7, m7 and all augmented and diminished intervals. P4 is dissonant when used harmonically above the bass
Enharmonic intervals
Sound the same but are spelled differently and therefore function differently
Root position triad
A triad with the root in the bass voice
Root position 7th chord

1st inversion triad
A triad with the 3rd of the chord in the bass. Inversion symbol: 6
1st inversion 7th chord
A 7th chord with the third of the chord in the bass. Inversion symbol: 6 5
2nd inversion triad
A triad chord with the 5th in the bass. Inversion symbol: 6 4
2nd inversion 7th chord
A 7th chord with the fifth of the chord in the bass. Inversion symbol: 4 3
3rd inversion 7th chord

Triad
A 3 note chord made up of two intervals stacked in thirds
7th chord
Contains four notes- a 3rd, a 5th, and a 7th
