The Strangest Normal Scale
 
Harmonic Major is really simple, except that it's not. It's just like the major scale except with a flat 6th degree, which seems straightforward enough, but the effect of lowering that one note changes pretty much everything, from creating all sorts of weird chords to adding bizarre intervals to its melodic structures. It's kind of in between major and minor, but there's plenty of other scales that are too, and most of them are a lot easier to use. So what's the point? Well...
