Define "musician". Basically I'm that guy who will play the first few bars of Für Elise on a piano, can't read music, and doesn't give any sign of knowing much more than that. This comment is a manifestation of that mindset, tbh.

Music theory interests me. I used to play a bit of keyboard and can strum a few chords on a ukulele, but I'm a billion light years away from being good enough to perform for people. Maybe I'd be OK in the background in place of a bass player, but you'd be better off with a prerecording or a computer standing in. Wrong sort of brain for practise, practise, practise.

But since you might like something interesting to look at, I have occasionally watched people like Heart of the Keys or There I Ruined It on YouTube, and dream that maybe, one day, I'd be able to do something like that.

HotK has done "1 minute, 10 minute, 1 hour" practise challenges with pieces she doesn't know, something that actual musicians might like to try and then discuss, and TIRI is just plain musical silliness.

Also Jacob Collier is a freak of nature and I wish I had his superpowers.
