Ask HN: How many of you play music?

Tangential question - can any of you recommend the best way of going about learning how to play the piano. Is the only way a tutor? I've picked up playing guitar for following tabs and YouTube videos, but don't seem to be having the same luck with piano.

I play 5-string banjo, 3-finger style. It grabbed hold of me and now it just sucks up my time.

But it's worth it. I'm getting pretty good, so who cares about doing actual work. :D
