E Dorian Bebop on Guitarrón

E Dorian Bebop runs 8 notes to the octave. Below it is mapped onto this instrument's A–D–G–C–E–A fingerboard with every E marked, because what a player needs mid-number is not the pattern but where the root is when the harmony moves under it.

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 bass takes almost no melodic line, and that is precisely why these matter: the notes between one root and the next come out of a scale, and an approach that lands wrong is the loudest wrong note in the ensemble.

Take it slowly against the playback until the geometry stops being geometry, then put it under a number in E major or minor and let the written line pick its own notes out of it.
