I was recently given a lovely flute in a high key as an early Christmas present (obviously, I couldn't wait until then to actually get and play it ) but I'm having a little bit of an issue with it. It wants to squeal and squeak. I don't think "over-blowing" is the correct term in this case because it seems to be occurring more with lesser streams of air than with moderate streams of air. It especially seems to occur with the highest two notes but does happen on the lower notes too. There was a sound sample on the maker's website and it could really sing, and I feel horrible that I cannot make it sing to its full potential.
Initially when I opened the package the bird seemed off-kilter on the nest (it was crooked and almost leaning out of the nest on one side) which I thought was just a result of it being moved slightly during shipping. I straightened it out a little bit and it seemed to be fine. However, playing it in small spurts throughout the day I've been having the squeaky syndrome problem. I've tried re-adjusting the bird again to try to re-locate the sweet spot and every time I think I've found it after one or two tries it will squeal on me again. I'm covering all the finger holes properly so that is not the issue, and I do not see any gaps at the bottom of the bird where it meets the nest.
I'm hoping that it might just have something to do with the flute getting acclimated to its new environment. It came from the West Coast where I'm sure it's much warmer than my chilly Pennsylvania apartment. Do you think that might be the cause of the problem, or is there something else I might be able to do?
Edit 12/09/08: The flutemaker kindly allowed me to exchange the flute for a similar one. I received the new flute today, and so far, so good! It sounds very sweet and clear.
