The C Lydian scale is a seven-note musical scale that is derived from the G major scale. It consists of the notes C, D, E, F#, G, A, and B. The defining feature of the Lydian scale is its raised fourth note, which gives it a bright and uplifting sound compared to the major scale. In terms of intervals, the C Lydian scale follows the pattern of whole and half steps: whole, whole, whole, half, whole, whole, half. This unique structure makes it popular in various music genres, including jazz and film scores, where composers seek to create a sense of openness and exploration.
