Bass Fills With B Dorian Bebop

B Dorian Bebop runs 8 notes to the octave. Below it is laid onto this chair's EADG fretboard with every B marked, because what a fill needs mid-song is not the pattern — it is where the root is when the chord changes 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 rarely takes a fill, and that is precisely why these matter: the notes between one root and the next come out of the scale, and a walk that lands wrong is the loudest mistake in the mix.

Play it slowly against the audio until the shape stops being a shape, then take it to a song in B and let the melody pick its own notes out of it.
