I was told by a judicator to try some buzzing on a mouthpiece everyday as part of my warmup to help get a more solid tone (with a piano). The reason it was kind of airy during this performance was mostly due to nerves, and I don't think I have much of this problem when I normally play except around F at the top of the staff after I have been playing for a while. (My range only goes to a G above that though). There is some excess air to my sound that I'd like to get rid of so what do you think of MP buzzing to solve this? Do you have any specific excercises to do with buzzing to help this? Are there any other suggestions as to how to get a more solid tone in a players upper register? Is there any other excercises non-buzzing related to help with this? (I do some breathing excercises daily too.) Thanks for reading.
