What it sounds like
Lydian dominant follows the pattern whole, whole, whole, half, whole, half, whole. It is the Mixolydian scale with a raised fourth. The raised fourth forms a tritone against the tonic, but the flat seventh keeps the dominant character. The result is bright at the top and still pulls toward resolution. Players often hear its extra note as a sharp eleventh over a dominant chord, which is why the scale is so widely used in modern jazz.
Where you hear it
Lydian dominant is used in jazz over dominant seventh chords with a raised eleventh, such as C7♯11. It appears in modern jazz, fusion, and some film scores for a bright but unresolved dominant color. Players often choose it for passages that avoid the normal resolution of a dominant chord. It is taught as the standard scale for the sharp eleven chord, and it is a common option whenever a dominant chord has a raised fourth in the melody.
How it is built
Lydian dominant is the fourth mode of melodic minor. On C, its pitches are C D E F♯ G A B♭, the same notes as G melodic minor, so C Lydian dominant is the fourth mode of G melodic minor. Compared with Mixolydian, it differs in one note: the fourth is raised. Its tonic chord is a dominant seventh, C7, and its second degree is also a dominant seventh, D7. The fifth degree is a minor chord with a major seventh, G mM7.

How to practise it
Play C Lydian dominant, C D E F♯ G A B♭, against a drone on C. Over a C7♯11 vamp, aim the F♯ on strong beats and resolve it down to F. Then play the same shape with F natural, which is Mixolydian, and compare the two sounds. Use the difference to decide when a dominant chord should sound bright and when it should sound plain.
Enharmonic spelling
G♭ and F♯ are the same pitch, so this scale can also be written as F♯ Lydian dominant: F♯ G♯ A♯ B♯ C♯ D♯ E. The spelling that needs fewer accidentals is the one you will usually meet.
