One more thing, related or not: I play guitar and keyboard. Not virtuoso but I can play. I can only remember chords I practised or used from muscle memory, and although I play both for over 25 years, I can't for the life of me remember the notes on the strings beyond the two E-s. Keyboards are easier for me in that regard. I also never remember chords for songs so me playing is pretty much either improvisations or having a song chords in front of me.
