Tones in a Harmonic Minor Bebop Scale : Root, Minor 2nd (m2), Major 3rd (M3), Perfect 4th (P4), Perfect 5th (P5), Minor 6th (m6), Dominant 7th (d7), Major 7th (M7),
The bebop harmonic minor scale (or bebop natural minor scale, as listed in Mark Levine's The Drop 2 Book) is derived from the harmonic minor scale and has a chromatic passing tone (an additional ♭7) between the 6th and the 7th notes. It contains all of the notes of both the harmonic minor scale and the natural minor scale (Aeolian mode) of the same root. It can be used on all three chords of a minor ii–V–I progression. It is the seventh mode of the bebop major scale: for instance, the C bebop harmonic minor scale has the same pitches as the E♭ bebop major scale.
