D Mixolydian Bebop — Bass (4-String)

The D Mixolydian Bebop scale runs 8 notes per octave in the bebop family. Below it sits on the Bass (4-String)'s EADG 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.

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.

In fourths tuning every pattern is movable: learn the shape once, one finger per fret, and it works from any root on the EADG neck.

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