i have been in and out this forum with the same basic problem. I have a Besson Prestige 2052 silver horn maybe about 4 years old (bought it new a little over 2 years ago). as i have said, the last time i had played a horn was back in the early 1970s, the last time with a band in 1969. I started again a little over 2 years ago on this horn. After 2 years, i still am extremely sharp on high notes, so sharp that even using the trigger to extend the slide, i am not getting in tune. I had thought that continue to practice would help. Last night i played with a band for the first time since 1969 and it was a disaster in that i could tell i was still extremely sharp compare to the other Euphonium. I do not know if it is the horn, the mouthpiece, or more likely just me. I have not figured out how to solve this problem. Not having someone local i can talk to about this and they observe my embouchure, i am at a loss of how to solve this. I tried playing a Bach Trumpet i have with a tuner and i am much closer to being in tune and i think i am much closer with the Conn Constellation Euphonium i have, although i am not sure because i sent it out to have some work done on it.
Has anyone any suggestions?
I know i am going to try some other brands of horns to see how they and i get along.
