B Dorian Bebop, Guitar Side

8 notes to the octave, mapped below onto this reader's EADGBE fretboard, with every B called out. Those markers are the useful part mid-bar: a chart moves under you, and the thing you need is where the root went — not where the pattern 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.

A chart names the chords and says nothing whatever about the notes between them, so everything a guitarist plays that is not a written chord comes out of a scale that the numbers only imply.

Play it slowly against the audio until the shape stops being a shape, then take it to a chart counted in B and let the numbers pick their own notes out of it.
