Hi all, I have a question regarding my higher register playing. I have been able to play the C above the stave since i can remember but recently i have found i can go higher than this to an F/G or even an A depending on if im having a good day. The problem is the sound gets too much of a squeal and the instrument dosent sound or feel like it wants to be there. I suppose i should say that its a seven year old Jupiter student model which has no problems with any other aspect of playing. Is it me needing to practice more? Is it just the fact that the instrument is a student model and shouldnt be up there? Or is it me needing to change mouthpiece if i want to sound good at that hight? I have been looking at a Jet Tone Leon Merian Sizzler model which says it is perfect for high register playing, is it worth buying it to see?
