The 시 Lydian scale contains 7 notes: 시, 도♯, 레♯, 미♯, 파♯, 솔♯, 라♯.
Lydian is the fourth mode of the major scale — a major scale with a raised fourth. The raised fourth removes the pull of the perfect fourth and leaves a floating, open sound used constantly in film scoring.
시 Lydian uses the same notes as 솔♭ 장조, started from degree 4 instead of the first. The notes are shared; the tonic, and therefore the sound, is not.
시 Lydian is a scale, not a key. It has no key signature of its own — music that uses it is normally written in the key signature of its parent scale, with any extra accidentals added as they occur.
