Ab Lydian Augmented Scale

What is the Ab Lydian Augmented Scale?

Lydian augmented is the third mode of the melodic minor scale, combining the dreamy #4 of Lydian with a #5 that pushes the brightness even further into otherworldly territory. It's a favorite in modern jazz for augmented major 7th chords, creating a sound that feels both familiar and strangely beautiful. Here's how the Ab Lydian Augmented Scale lays out on the fretboard. This scale is enharmonically equivalent to G# Lydian Augmented.

Notes and Positions

Lydian with a raised 5th; 3rd mode of melodic minor. Bright and ethereal. 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 Ab, the notes are: Ab, Bb, C, D, E, F, G.

How to Use It

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

Loop a simple drum groove and keep every note locked to the subdivision before adding fills. Use the interactive fretboard above to spot repeats of the same note on different strings and frets.
