A Lydian Mode

What is the A Lydian Mode?

Lydian is the fourth mode of the major scale, distinguished by its raised 4th degree (#4) which creates a dreamy, floating sensation that sounds like the major scale but brighter. You'll hear it in film scores, Steve Vai solos, and Joe Satriani's melodic work — any time a composer wants to evoke wonder or weightlessness. Here's how the A Lydian Mode lays out on the fretboard.

Notes and Positions

The fourth mode - dreamy major with raised 4th. Very bright. 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, F#, G#.

How to Use It

You'll often hear it in Film Scores, Jazz, and Progressive Rock. 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.
