Mandolin Fills With A# Dorian Bebop

A# Dorian Bebop runs 8 notes to the octave. Below it is laid onto this chair's GDAE fretboard with every A# 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.

A mandolin fill is short and often tremolo-doubled, so the scale here is a source of two- and three-note runs between the vocal phrases, not a ladder to climb.

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