What is the A# Bebop Dominant Scale?
The bebop dominant scale adds a passing natural 7th to the Mixolydian mode, creating an eight-note scale designed for one specific purpose: keeping chord tones landing on downbeats when you play running eighth notes. It was pioneered by Charlie Parker and Dizzy Gillespie and remains essential vocabulary for jazz improvisation. Here's how the A# Bebop Dominant Scale lays out on the fretboard. This scale is enharmonically equivalent to Bb Bebop Dominant.
Notes and Positions
Mixolydian with added major 7 for even eighth-note phrasing. On guitar, you can treat this as both a lead vocabulary and a way to see chord tones inside common shapes. Start with one box, then connect it to the nearest root on the next string set. In the key of A#, the notes are: A#, B#, C##, D#, E#, F##, G#, G##.
How to Use It
You'll often hear it in Bebop, Jazz, and Swing. A good way to internalize the sound is to sing the root, then sing a few scale degrees before you play them.
Practice in small fragments (3-4 notes) and connect them across adjacent positions. Use the interactive fretboard above to spot repeats of the same note on different strings and frets.
