B Dorian Bebop — Bass (5-String)

The B Dorian Bebop scale runs 8 notes per octave in the bebop family. Below it sits on the Bass (5-String)'s BEADG strings with every root marked, because a bassist reads a scale map as a set of targets around the root, not a row of dots.

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.

In fourths tuning every pattern is movable: learn the shape once, one finger per fret, and it works from any root on the BEADG neck. With the low B in the tuning, the same fingering covers more range before your hand ever shifts.

Walk it slowly against the audio, land each root on a downbeat, then take it to the progressions in B and let the scale turn into lines.
