In this lesson, we’re going to learn how to play the Lydian mode in all 12 keys. The Lydian mode belongs to the set of scales called the Major Modes. The Major Modes consist of seven scales derived from and using the same notes as one parent Major scale, but starting and ending on each of the different degrees of that parent scale. Lydian is the 4th Mode of the Major scale, so it starts and ends on the 4th degree of its parent scale. Lydian has a bright, airy, and somewhat mysterious sound; it works well over Major triads, major 6th chords, Major 7th chords, and Major 6/9 chords. Lydian is in fact only one note different from Major. We’ll learn the right and left hand Lydian mode fingerings in all twelve keys.
