A simple chart with music concepts that i put together

Hey.

Maybe you will like it.

I apologize for reposting it from another service; my account there had been limited for some time after registration, resulting, i believe, in my post not reaching people who had subscribed to its tags; and i suppose it is not wrong to want to reach some people once one has decided to post something in the first place. Anyway, sorry about that.

Thank you.
