I play on the schools 50 somethin'-year-old bari and it is just awful. It is a fun horn with a great tone it's just stuffy sometimes and half my notes are over 30 cents sharp or flat. Is this problem me? (I can play my tenor and alto almost perfectly in tune) or is it just the horn? I plan on sending the horn to the shop over vacation anyway. I am really not the best pitch bender yet but I really don't think my lips should have to jump around that much. Again, Is this me or is t the horn?
