In music, the acoustic scale, overtone scale,[1] Lydian dominant scale (Lydian ♭7 scale),[2][3] or the Mixolydian ♯4 scale is a seven-note synthetic scale. It is the fourth mode of the ascending melodic minor scale.[4][5]

This differs from the major scale in having an augmented fourth and a minor seventh scale degree. The term "acoustic scale" is sometimes used to describe a particular mode of this seven-note collection (e.g. the specific ordering C–D–E–F♯–G–A–B♭) and is sometimes used to describe the collection as a whole (e.g. including orderings such as E–F♯–G–A–B♭–C–D).
