Hello,
I've actually learned piano for 7 years as a child, and have recently picked up a big interest in it again. However, when I was a kid, it was mostly scales then "memorize this piece" and "memorize that piece" and I managed to learn absolutely nothing about music as a whole. I'd love to just be able to sit down at the piano and play whatever comes to me, but to be honest, I really have no idea where to start.
I'm just looking for any recommended books, beginner books even, that help teach the theory behind music so that I can just sit down and play in whatever key I like. I realize that takes years of practice, but I'm just looking to be pointed in the right direction so I am no longer at the mercy of whatever is printed on the music sheet. Any advice / book recommendations / good learning websites (they all seem to be so shady!) would be so helpful, thank you!
