Help, My M&E flute head joint stopper came out
I have a question, last week I noticed my flute going sharp in the higher register and the stopper was loose. Last night a a session the stopper on the head joint came off. Know there is no sound coming out of the flute. Obviously it make a noise, however I cannot play any notes. I did not notice anything else that came off with the stopper, I put teflon tape on it to make it snug again, however still nothing. I added a bit of cork in the stopper & again no change. I dont want to glue anything just yet as I may be missing something that I am not aware of. I live in a rural area & no one in about 1.5 hours drive can work on this flute, boehms yes but keyless no.
Is there anything that I am fundamentally missing??? Any help would be grateful.
