F# Mixolydian Bebop — Viola

F# Mixolydian Bebop is 8 notes to the octave (bebop family), drawn here along the Viola's CGDA strings with every F# named, so home is findable from any finger.

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.

Because the strings climb in fifths, one hand position covers a wide span of the fingerboard — four fingers, a fifth of range per string, and the same finger pattern repeating across every neighbouring pair. Learning a scale here is mostly learning WHICH position it wants and where the shifts fall.

Open-string drones: none. Not one of the Viola's 4 open strings — C, G, D and A — belongs to F# Mixolydian Bebop, so this scale has no open-string reference at all, and intonation has to come from the fingers alone.

Play it slowly with a long bow, one note to a stroke, and listen for the notes that pull sharp or flat against the open C and A. Intonation on this instrument is a conversation with the open strings — nothing on the fingerboard decides it for you.
