Lydian Dominant combines the bright lift of Lydian with the pull of a dominant seventh sound. Its color comes from the tension between ♯4 and ♭7: one note opens the harmony upward while the other keeps strong dominant function. This makes it a central sound in modern jazz, fusion, and harmonic color writing.
Construction and formula
Lydian Dominant follows 1-2-3-♯4-5-6-♭7, with step pattern W-W-W-H-W-H-W. In C Lydian Dominant, the notes are C-D-E-F♯-G-A-B♭. In modal terms, it is the 4th mode of melodic minor (for example from G melodic minor).
Compared with Mixolydian (1-2-3-4-5-6-♭7), only one degree changes: 4 becomes ♯4. That change keeps the dominant frame intact while adding a more modern, floating tension.
Musical usage
Lydian Dominant is commonly used on dominant chords that do not resolve in a strict classical way, or that resolve with colorful modal motion. It appears frequently on V7-type sonorities in jazz contexts where ♯11 color is desired.
Melodically, emphasizing 3, ♯4, and ♭7 quickly defines the mode. Harmonically, voicings with 3-♭7 and an added ♯11 make the sound immediately recognizable.
Examples
- Jazz dominant lines with clear ♯11 color over static or moving harmony.
- Fusion progressions using bright dominant tension without harsh altered density.
- Film cues that need forward motion with controlled harmonic ambiguity.

In practice
Practice Mixolydian and Lydian Dominant on the same root, focusing first on 4 versus ♯4 while keeping ♭7 constant. Then write short motifs that target chord tones and repeatedly color the line with ♯4/♯11.
For improvisation, connect it to melodic minor families and dominant chord function rather than treating it as an isolated fingering shape. For composition, use it when you need dominant energy with brighter harmonic space.
