by the way, the 'transpose by # semitones' is pretty ridiculous. Say you want to change from C key to Ab key, you don't go 'how many semitones? 1, 2, 3, 4.....'. Who changes key like that, probably children. You simply know that the Ab key has four flats that aren't found in the key of C, end of story. That's what the circle of fifths shows very clearly, the DIFFERENCE between one key and another, in sharps, flats, and naturals. Not the number of semitones, these don't matter. Besides, it's a pain to think, ok up a fourth, how many semitones....1...2....3...4...5.... feels like counting beans.

So at least let's use intervals. Up or down a semitone it's ok, but from then on should be intervals: major second, minor third, etc. Let's use basic music theory instead of reinventing the wheel over and over.
