maj7♯11

The major seventh sharp eleventh is the sound of the lydian scale: a major seventh chord whose raised fourth lifts the whole harmony off the ground. The sharp eleventh sits a tritone above the root, but in this context it does not pull toward resolution — it floats, which is why film composers reach for it in wonder-and-space moments and jazz players use it over a major chord that refuses to sound ordinary. The chord keeps its warm major third and seventh underneath, so the tension stays luminous rather than dark. Listen for the shimmer where the sharp eleventh meets the fifth; that wide, open interval is the signature.
