All you guys have been so helpful in the past with my playing that I thought that I'd try you again! Firstly, I have developed a mouth ulcer on the inside of my lower lip that I have had for over three months now, and it is without doubt having a negative effect on my trumpet playing. I have been to the doctor, and he seemed to think that the only way to get rid of it would be to stop playing the trumpet for about a month! Clearly, as trumpet players yourselves, you can understand this just isn't a feasible option! So do you have any ideas of what I can do? I've tried so many over-the counter medecines and creams etc - I'm at a loss! Secondly, I am looking to change my mouthpice: I have an exam in March for which I have to play Fanfare for the Common Man, the Haydn Concerto, an Arban etude, and the usual scales, sight-reading etc, and it is such a struggle to get through all of this on my current mouthpiece, which is a Bach 1 1/4 C. I was thinking about changing to a 3c, or the Schilke equivalent, but I would appreciate your thoughts on the matter too! Finally, and this is a quicky, do you think that the 2nd movement of the Haydn is an appropriate piece to play in an audition, or would you recommend something more difficult, demonstrating greater skill? I really appreciate your help, many thanks! Chris H.
