Piano: C Dorian Bebop Over the Changes
Where C Dorian Bebop lies at this seat, and what a chorus takes out of it.
C Dorian Bebop runs 8 notes to the octave, laid out here across 88 keys with every C flagged. Mid-chorus the pattern is not what you need; where the root is when the chord changes underneath you is.
Dorian with a chromatic passing tone slipped between the b3 and the 4 — eight notes, so chord tones keep landing on the strong beats in a run of eighth notes. Cool, flowing, and swinging.
Heard in: Bebop and straight-ahead jazz lines over minor seventh chords — Charlie Parker, Dizzy Gillespie, and the Barry Harris approach.
The right hand takes the line and the left keeps stating the chord under it, which makes a scale at this seat a two-handed problem: the notes have to work against a voicing you are choosing at the same time.
Play it slowly against the audio until it stops being a shape, then put it over two bars of a form and let the chord tones decide which of the notes you actually keep.
