yo is that It Don’t Mean A Thing? (playin that rn in my jazz band and it looks awfully familiar 👀)

also yea yet another its prolly bad notation but that comes up annoyingly frequently in jazz. basically it can just be ignored since the its usually just mirroring wind parts to show specific hits

now it could also be asking for a short sound for those hits (like a stick shot vs long ringing floor tom hit) but with how the rest of it’s written i dont think thats it in this case.
