This was one of the first pieces I tried to learn as a kid. I would just restart it repeatedly because my Casio keyboard had a library of classical music on it that one could listen to by hitting a function key and then a unique white key. I think it's something that Casio did in the late 80s - mid 90s. They don't seem to use the old song library much or at all anymore, but I thought it was a great feature. So I'd just restart from the beginning and learn the next note. Guess-and-check. As an adult I've continually tried to learn to read sheet music, with frustration. So I learned jazz theory and invented my own music theory system. Now I encode most pieces harmonically in my brain. It would be cool to see this kind of indication in the app, so for example, the first couple lines: 3/4 |C#mi| | | |C#mi/B | | | | |A | |D/F#| |G#5(b6)|C#mi/G#|G#sus|G#7 | ... I like to use this as a jam idea, for example play it like a montuno.
