I've just purchased a 61-key keyboard, the Yamaha PSR-E253. I know it's not the best to start with, as it lacks touch sensitivity, especially so for those serious in their learning. I will purchase a high-end digital piano in due time. I've picked this one up to learn how to play.
What I'd like know is whether I can play most popular music songs on a 61-key keyboard. Specifically, the Beatles, the Rolling Stones and 60s work. Certainly other music too, but I'd like to start with the music I like before progressing to the classical music I enjoy.
