G# Dorian Bebop, Piano Side

8 notes to the octave, lit below across two octaves of this reader's keyboard, with every key numbered by where it sits in the scale. The numbers are the useful part mid-bar: a chart moves under you, and the thing you need is which degree is still under the hand — not where the run started.

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 fill and the left keeps the written number sounding under it, so a piano reader hears every note of the scale against the chord the chart called rather than in place of it.

Run it hands together until the window stops being a pattern, then take it to a chart counted in G# and let the numbers pick their own notes out of it.
