C Bebop Major Scale

What is the C 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 C Bebop Major Scale lays out on the fretboard.

Notes and Positions

Ionian with chromatic passing tone between 5 and 6. On bass, this scale becomes a toolkit for strong roots, passing tones, and melodic fills that still support the groove. Think in root-on-E and root-on-A boxes, then adapt the same notes for 5-string bass when the low B string gives you another root below the pattern. In the key of C, the notes are: C, D, E, F, G, G#, A, B.

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.

Build two-bar bass lines that return to the root before experimenting with wider melodic movement. Use the interactive fretboard above to spot repeats of the same note on different strings and frets.
