Q: if 8th-notes are "1&2&" how do you prefer to count 16th-notes out loud?
A: i use the 1e&a2e&a system, although it's not really used for actually counting consecutive 16th notes, it's more like an address system, to refer to a point in time. like you might tell your trumpet players to play the hit "on the e of 2" that means it's the second 16th note of beat 2. similar to how you might say "on the & of 2" which would mean halfway in between beat 2 and 3
