I hope this don't get me banned. looked at all the threads in B flat Clarinet. three pages, did not see this one. I have a clarinet that plays one note low. I finger E it plays D. consistent through out all notes it is always one lower. never two or three. have two mouthpieces and 3 reeds. still consistent. I even used the same tuner, (there's an app for that), on my flute and an E was an E, a D was a D. I even took a tissue paper and put it under each normally closed holes and pressed it down to hopefully get a good seal. no change all the way up the clarinet. any clues?
