Alright, the majority of you have been and possibly are under stress. This year has been over the top with school work, family issues, and yadayadayada. I held it off pretty well, but I finally hit my breaking point when my grandfather passed away about a month ago. I noticed when I came back to playing my tone was literally crap. No other way to put it. A month ago my tone matched the first chair's, nice and clean. Now its just dirty, mushy, and to tell the truth not mine. I have been having more stress piling on, and I notice that my tone is just decreasing and decreasing every day. I do my long tones and slurs everyday, its been the same routine for as long as I can remember, but all of a sudden my hard work seems to have been thrown away. Is stress related to this sudden decrease in tone quality? Also we have to play at graduation and we NEED to sound good, so does anyone here have any suggestions as to how I might be able to fix this problem?
