What is a tritone, and which two written intervals can it be?
An interval of six semitones (three whole tones). Written as an augmented 4th (e.g. F-B) or a diminished 5th (e.g. B-F); the spelling decides the name.
How do you invert an interval and what happens to its quality?
Move the lower note up an octave. The numbers add to 9 (3rd becomes 6th) and quality flips: major to minor, augmented to diminished; perfect stays perfect.
How is a compound interval such as a 9th related to a simple interval?
A compound interval is wider than an octave: add 7 to the simple number (2nd + 7 = 9th) and keep the quality, so a major 2nd plus an octave is a major 9th.
What are enharmonic intervals?
Intervals that contain the same number of semitones but are spelled differently, such as an augmented 6th (B♭-G#) and a minor 7th (B♭-A♭). They sound the same but are named differently.
Spell the D harmonic minor scale ascending.
D, E, F, G, A, Bb, C#, D.
Spell the A melodic minor scale ascending.
A, B, C, D, E, F#, G#, A.
Spell the G mixolydian scale ascending.
G, A, B, C, D, E, F, G.
Spell the C dorian scale ascending.
C, D, Eb, F, G, A, Bb, C.
Spell the E flat major scale ascending.
Eb, F, G, Ab, Bb, C, D, Eb.
Spell the C major pentatonic scale and state which degrees it omits.
C, D, E, G, A. It omits the 4th and 7th degrees, so there are no semitones, which gives its open, folk-like sound.
Spell the A minor pentatonic scale.
A, C, D, E, G (degrees 1, b3, 4, 5, b7). Adding the blue note D# or E♭ turns it into the A blues scale.
