Hello everyone. I am a freshman at my high school and am using a Jet-Tone Custom DS B mouthpiece (yes the old version) that my private teacher gave me for our musical. The musical is Rodger's and Hammerstein's Cinderella. (I know its really not that difficult but I'm lacking in range a little and the only other player that can play the music is a sophomore so I was given 1st part as well) Anyway with this mouthpiece I can handle the music ok. I just have a HUGE issue with tuning. Typically anything past a D in the staff becomes very sharp. I still use my slides to counter but say if I play a F# with second its horrid. I also have a hard time matching up with my partner on 1st as well because its so bright. (He's on a model 37 Stead with a 5c if that's important)
What should I do to not be sharp? I really can't switch mouthpieces because the show is coming up. I play on a Xeno with a reversed tuning slide also.
