I have been learning musictheory.net. It seems adequate for reading notes. But, I don't know how much I want to learn about music theory if I want to play an electronic keyboard well enough to enjoy doing it and to progress.
I realize, if I wanted to write music later, then I might need to learn more than the basics taught on musictheory.net.
But can I just play keyboard for the fun of it, it it necessary to learn music theory?
