A# Bebop Major Scale

What is the A# Bebop Major Scale?

The bebop major scale inserts a chromatic passing tone (#5/♭6) between the 5th and 6th degrees of the major scale. Like its dominant cousin, the extra note ensures that chord tones fall naturally on the strong beats during eighth-note lines — a rhythmic alignment trick that gives bebop its characteristic fluid sound. Here's how the A# Bebop Major Scale lays out on the fretboard. This scale is enharmonically equivalent to Bb Bebop Major.

Notes and Positions

Ionian with chromatic passing tone between 5 and 6. On bass, the fretboard view helps you visualize where the important tones sit for building lines across positions. Use a finger-per-fret approach first, then add shifts only when the line needs a wider range. In the key of A#, the notes are: A#, B#, C##, D#, E#, E##, F##, G##.

How to Use It

You'll often hear it in Bebop and Jazz Lines. A good way to internalize the sound is to sing the root, then sing a few scale degrees before you play them.

Start with the root on beat 1, add the 5th on beat 3, then work the other scale tones in as passing notes. Use the interactive fretboard above to spot repeats of the same note on different strings and frets.
