What is the C# Lydian Dominant Scale?
The Lydian dominant scale is the fourth mode of the melodic minor, combining the raised 4th (#4) of Lydian with the ♭7 of Mixolydian. The result is a bright, slightly "outside" dominant sound that's a staple of fusion and jazz — perfect for dominant chords that don't resolve in the expected way. Here's how the C# Lydian Dominant Scale lays out on the fretboard. This scale is enharmonically equivalent to Db Lydian Dominant.
Notes and Positions
Mix of Lydian brightness with a dominant 7th for V chord color. On guitar, the same scale tones repeat in multiple positions, so the real goal is learning how to connect shapes up and down the neck. Use the CAGED boxes as smaller practice areas before linking the full fretboard. In the key of C#, the notes are: C#, D#, E#, F##, G#, A#, B.
How to Use It
You'll often hear it in Jazz, Fusion, and 7#11 chords. 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 backing track in the same key and target the root on strong beats. Use the interactive fretboard above to spot repeats of the same note on different strings and frets.
