Yes, to a certain extent. The &'s mean something in the sense that we're calling them &'s for a reason.
&'s to what??? Answer: To the 1,2,3,4. What are 1,2,3,4? Quarter notes. There's your tempo.
If the &'s were 1/4 notes, we wouldn't be calling them "&'s". We'd be calling them, 2 & 4. THEN, the tempo would be 320bpm.
Fuck. You just lost me. So close. So if it's just wording, then how does it matter? Why can't we call the &'s 2 and 4? The crazy way I'm counting it, the snare would be on 2 and 4. I can hear it both ways.
