I couldn’t lessons in this. So firstly, does it even exist?
Secondly if so how do they work? Is it like regular scales that A harmonic/melodic Minor is the relative minor of c harmonic/melodic major or is it simply that for harmonic major you sharpen the 7th note in the major scale and sharpen the 6th and 7th note of the major scake for the melodic major scale?
