For many brass players I know, the feeling of "morning chops" is all too familiar - playing at any hour of the morning, before noon, gives them stiff-feeling and/or unresponsive chops. Through simple research, the most I've found as a remedy to these kinds of players is things like drinking lots of water in the morning, getting enough sleep, and warming up longer and slower than usual.
I would classify myself at the very least as an EXTREME case of this. If I play any less than 6 hours after waking up, I am an unrecognizably different player. My range suffers anywhere from a third to a perfect fifth, and my tone, power, and articulation goes out the window. Being a lead player, this is obviously incredibly inconvenient. To put this into context, I woke up at 7am today, had a big band rehearsal at 12pm, and could not play above a high E almost at all. My range typically extends to strong high A's and double C's. Throughout the rehearsal my chops felt stiff and unresponsive. This rehearsal lasted 3 hours, and I left it horrified, wondering what I possibly could have done to destroy my chops so badly. However, just 2 hours after the rehearsal, at the nice playing hour for me of 5pm, I took out the horn and it turned out my chops were completely fine, if not BETTER than usual. I was tired from the rehearsal, which showed, but I still had strong high G's and A's. It was clearly the morning chops that did me in here.
As I'm sure is evident now, this is a rather alarming inconvenience for a high schooler like myself who plans on doing music in college, as I will not survive if I'm entirely unable to play for this long of a time after I wake up. So my question is, has anyone had this extreme of a problem with the dreaded morning chops, in both (or either) the unreasonable length of time I have to wait after waking up and the severity of deterioration my playing suffers if I do play at these hours? If so, is there any sort of diagnosis for why this happens to me/what can be done to fix it? The simple water in the mornings and longer warmups have not been nearly enough to fix it for me.
