A Mixolydian Bebop — Dobro

A Mixolydian Bebop runs 8 notes to the octave. Below it is laid onto this chair's GBDGBD neck with every A marked, because what you need mid-break is not the pattern — it is where the root is when the chord changes under you. A is one of the four keys a circle calls, so this one comes up.

Mixolydian with a passing major 7th between the b7 and the octave — the bright, bluesy dominant sound with a chromatic slide that keeps every chord tone on a downbeat. Slick, swinging, and quintessentially bebop.

Heard in: Jazz lines over dominant seventh chords, blues changes, and rhythm changes — the workhorse bebop scale.

A dobro break is slid, not fretted: the bar travels to each note, so a scale here is a list of places the bar may stop on the way — and on open-G strings, the stops that ring against an open string are the ones the melody keeps coming back to.

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