When calculating bpm, do you just count the 1 2 3 4 (assuming a simple 4/4 time signature), or would you sometimes count the "and"s as well? If a song has a very strong 1 and 3 and a very weak 2 and 4, do you still count the 2 and 4? There are other permutations of this question I can think of having to do with different time signatures. I'm kind of guessing that the answer is that you always count whatever the first number (e.g., 6 in 6/8 time) indicates and it's as simple a that, but curious to know if it's sometimes more complicated (or different). Thanks.

Usually, yes. Although, this can depend on the time signature & the intention of the composer/performer.

An exception example would be cut-time. In this case the beat is on the half-note. It can help to write & read the notation to do this.

[p]Usually, but always. For example, in 6/8 you usually count on 1 & 4 as the dotted quarter note gets the count. In 12/8 you usually count on 1, 4, 7, 10.

Hope that helps!
