@mrsaturday @why @sun Piano is great for general "music" learning because it's complete. It covers the whole staff, it does notes and chords, keys, it covers melody, rhythm, accompaniment, it can cover almost any part in any song. You can also play most songs in a way that feels "complete" on your own on the piano.

I tried to (well, keyboard, but pretty much the same conceptually), but I never could learn it, it feels way too overwhelming to me.
