I've just picked up trombone, for the first time. I find it really enjoyable to play, but I'm having trouble with my beard and mustache. As far as I can tell, it doesn't affect the sound at all, but after a while playing, the area above and below my lips - at the top and bottom of the mouth piece, starts getting itchy, due to the pressure. I don't get this with trumpet, I guess because of the smaller mouth piece.
I'm wondering if anyone has any experience playing trombone (or tuba perhaps) for extended periods with a beard? Do you become accustomed to the sensation, or does it remain irritating? Do different beard lengths have different effects? Does it ever get to the point where the hair affects your sound?
