A and B can go either way tho..

Answer 2

It depends on how technical you are. Kind of yes, but mostly no. If you’re taking a music theory class, the answer will be no. In compound time signatures, the time signature is more of a code you have to decipher to find how many beats there are since the beats are divided into three.
