D Lydian on Guitar

Lydian is the major scale with the 4th raised a semitone — major, but floating instead of grounded. The notes of D Lydian are D, E, F#, G#, A, B, C#. Its characteristic note is G# — the sharp 4th — the one note that gives this major-type scale its colour.

It is the dreamy, weightless sound of film scores, "The Simpsons" theme, and Joe Satriani ballads ("Flying in a Blue Dream" is a Lydian tutorial with a record deal). The sharp 4th refuses to resolve downward the way a normal 4th does, so the whole scale hovers.

Over the drone, hold the sharp 4th and let it ring — in any other major context it would be a wrong note; here it is the point.
