I'm a high school player, and for the past month I've been playing at least 3 hours a day, including the lead part in my high school jazz band (which doesn't go above a high C because frankly the we aren't good enough to play hard charts, but still). Over the past few weeks, I've noticed a definite decrease in my ability, including a decrease in range (from a weak high C to barely being able to get out an A) and a very very marked decrease in endurance. Things that were not difficult a while ago are now undoable. I haven't changed my practice rountine at all, and I've been making sure I use the bucket trick to make sure my air support is solid. I've also cleaned out my horn, in case there was a blockage. Further, I feel my chops just "give out" when trying to play high(er) for extended periods of time. All of this leads me to believe I need to take a few days off the horn to recover, because I think I am overpracticing. What are your thoughts? Is this a case of overpracticing, or something else? I'm thinking of taking Saturday and Sunday off, because I have no playing commitments. Is this advisable? Thanks for your help. I would be happy to provide any more information if needed.
