Lydian is the fourth mode of the major scale. It is produced by starting on the fourth note of the major scale and playing up to the fourth an octave above. For example, F lydian consists of F G A B C D E F, since F is the fourth note in the C major scale. The scale intervals relative to the root are 1 2 3 #4 5 6 7. Lydian has a very “bright” sound, even brighter than major, due to the #4. Lydian can create a sense of wonder and awe in music, and is frequently heard in film scores.
