Hey, I have what it seems like a basic question, but I'm a bit confused... First of all, we can all agree that 80bpm and 160bpm are pretty much the same - it's just that the metronome clicks twice as fast (we may want to go double time for some reason such that it helps us play a certain melody better) So let's say that I rap the first verse of 16 bars and my friend raps the second verse of 16 bars at 80bpm on some melody. Then let's say that I rap those bars on that same melody at 160bpm (BUT please keep in note that the melody's tempo isn't just simply increased by changing the BPM value - I've re-recorded the melody at 160bpm so that the melody plays at the exact same speed at what it played at 80bpm). Also, I will rap at the same speed regardless of 80bpm or 160bpm, YET my friend doubles his rap speed when going from 80bpm to 160bpm. Will my rap verse still count as 16 bars or will it be 8 bars on 160bpm? What about my friend's verse? I apologize for my confusion, as well as if I have confused anyone else in my explanation. Thank you.
