Manny, I remember reading a post of yours on double buzz, but I can't seem to get it using the search function.... Anways, I was playing through the Arutunian today, and I started to get a slight double buzz in the mute section. I remembered your post (while I was playing on stage) and how you said double buzz usually occurs due to breathing ineffiency. I couldnt for the life of me get the buzz to go away. Once I got the chance to rest after the mute section, it was gone, then it reappeared a little ways into the Allegro right before the cadenza. Can you help me visualize the problem? I was trying to breath deep from the diaphram and not move my chest, and keep my stomach muscles relaxed, but somthing was wrong. Ir seemed like it was caused by my lips... but I'm not really sure whats going on. Any input would be appreciated. Thanks!
