Music Box - First Loop

This is the first video showing the loop (right-side up and upside-down). I am working on a Bach crab canon that will go front, back, up, and down. But the transcription from original key e-flat, I think it was to two-octave natural C major. That isn't going to smoothly cuz I have to modify the tune. But... I persist. :-) I did this once years ago when I did some computer music in the 1980's. So I know I "Can" do it. I just am not good at it. I need to go back and learn music again. :-0
