No, UVULA, and it has nothing to do with female reproductive organs. The uvula is the danagly down thing in the back of your mouth hanging down over your throat that has no apparent function. Just like the uvula in your mouth, the clarinet part that I am referring to has no function that I can figure out. It is located on the inside of the lower end of the upper joint. It is associated with a lever that is on the bottom side of the upper joint. I can't tell for sure, but it appears to be a very small piece of leather atached to a plastic(?) plug that fills a hole that the aforementioned lever covers. When pressed the lever lifts off of the plug. I am surmising that the tiny piece of leather is used to remove and/or replace the plug in the hole, but that is pure speculation. Now, what is this little uvula really called and what purpose does it serve?
