Online resources for learning piano

So these guys just arrived with a piano. It’s sitting behind me as I type. It’s a pretty nice one, 1920’s Chappell baby grand. Sadly, I can’t play and neither can the wife*. On the assumption that q23 is packed with gun pianistas, does anyone know any good online teach yourself piano sites?

*I play cello, and I can improvise okay on the keyboard by jamming on chords, but i’m wanting to learn to read some simple pieces as a more solid basis to that.

I think your best bet is to first invest in a few lessons. Just the instruction on posture, fingering and the ergonomics of the piano are priceless and will put you in a much better position to teach yourself from books or whatever without developing carpal tunnel. I say this as a mostly self-taught keyboard player who developed carpal tunnel.

The piano lessons I eventually took were some of the best money I’ve spent as a musician.
