What is the Gb 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 Gb Bebop Major Scale lays out on the fretboard. This scale is enharmonically equivalent to F# Bebop Major.
Notes and Positions
Ionian with chromatic passing tone between 5 and 6. 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 Gb, the notes are: Gb, Ab, Bb, Cb, Db, D, Eb, F.
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 by playing one position slowly and saying the note names or degrees out loud. Use the interactive fretboard above to spot repeats of the same note on different strings and frets.
