E Mixolydian Bebop — Venezuelan Cuatro

E Mixolydian Bebop is 8 notes to the octave (bebop family), drawn here across the Venezuelan Cuatro's A-D-F#-B strings with every E marked, so home stays visible from anywhere in the pattern.

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.

Four strings inside a major sixth put a scale in a deliberately cramped place: the same pitch turns up on two strings constantly, and one open string sounds below the string next to it, so a run that looks like it climbs on paper can fall under the fingers. These maps light every root so the ear has an anchor.

Use it the way the music does — in short pieces, between strums. Very little of this repertoire asks a cuatrista for a long scalar run; what it asks for is three or four notes that land exactly where the strumming hand was about to brake.
