I had band camp this week, Monday-Friday from 12p-9p. Earlier this week I noticed a painless white spot or section on my bottom lip. Yesterday the spot seemed to swell after 1.5 hours of playing. I had a little rest yesterday for about an hour and it went down, but had no choice but to play after that (there was another hour break later, for dinner). After practice I iced it, but it is still white. I am one of 8 brass players, and one of three trumpets; there are at least twice as many woodwinds. Quite a few sections in our music are forte or fortissimo, and one is fff. I dislike playing above forte because of the many problems that can come with that. I have no chance to ease up on volume because the directors have said several times that they can hardly hear the trumpets/trombones/tuba on the field at times. The highest note I repeatedly is a high A-flat, which I can do well if I take a good breath breath beforehand. There is a high C at the end of the show and in another song, but I don't play that any louder than mf. I like to rest as much as I play, but the directors have either never heard of that, or don't care (I do realize that this is valuable practice time for the band). Not even our temporary drill instructor, -who plays some brass instrument in another band and occasionally conducts practice in place of our band's actual director- gives us much rest; all wind players are either in or out. Two- to five-minute water breaks are nothing. Fortunately, my lips were never too tired to play, but I don't like to play so loudly, regardless. I've not yet practiced today, but there's no pain, although it's still white. Even if it's nothing, how can I better project my sound? One more thing: I have noticed that my lips became very dry twice this week, but that may be due to the combination of this long week and that I often lick my lips before playing.
