How have I played guitar this long and not known about the harmonic minor scale? Have you guys been holding out on me or something? I stumbled onto it accidentally. Seems straightforward. You take a major scale and flat the 3rds and 6ths. b3=m, got it. Knowing this scale now explains some of the weirdo notes I would sometimes come across in learning certain solos. But now that I know what it is, my question is how do you apply it? When do you use it? In the video where I discovered it, the guy was playing something in Am, and when he got to the E chord in the progression he said something like, "we're on the E so now of course we hop over to the harmonic minor scale..." And I'm thinking "huh?" Any tips?
