E Mixolydian 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.

Mixolydian with a passing major 7th between the b7 and the octave — the bright, bluesy dominant sound with a chromatic slide that keeps every chord tone on a downbeat. Slick, swinging, and quintessentially bebop.

Heard in: Jazz lines over dominant seventh chords, blues changes, and rhythm changes — the workhorse bebop scale.

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 E and let the numbers pick their own notes out of it.
