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. This scale is enharmonically equivalent to Db 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 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.

Practice root-on-E and root-on-A boxes separately, then connect them with one clean position shift. Use the interactive fretboard above to spot repeats of the same note on different strings and frets.
