G Lydian on Guitar

Lydian is the major scale with the 4th raised a semitone — major, but floating instead of grounded. The notes of G Lydian are G, A, B, C#, D, E, F#. Its characteristic note is C# — 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.

Standard tuning, frets 0–12. The gold notes are the root (G); every colour marks an interval, the same palette the app uses.

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.

Formula and intervals

R - 2 - 3 - b5 - 5 - 6 - 7 — 7 notes. The natural 3rd makes it a major-family scale.

G Lydian contains exactly the same notes as D Major. Nothing about the notes changes — what changes is which one feels like home, and that changes everything about the sound.
