What is the fundamental difference between the Lydian and Major Scale?
As described in the answer to the previous question, the Lydian Scale has one single tonic, otherwise known as the DO of the scale. The Major Scale is known as a diatonic (meaning: two tonic) scale. Therefore, the essential difference between these two scales is that the Lydian (a single tonic scale) is in a state of unity with itself, and the Major Scale, with its two tonics, is in a state of resolving.
