okay, so here's the situation: I have a flute recital tomorrow, and all of a sudden, my flute's gone screwy. My high D and low C# aren't working right. The note comes out, but it sounds VERY wrong. Please help me before tomorrow!!!!

it could be a loose post, make sure the posts are securely screwed on, it could also just be a displaced spring...check to make sure the springs are in the right place...

Yes, low D and C work fine. I think it's working again.... I cleaned it just before it went all weird. Maybe it was still drying out???

MIcron, I didn't mean post, my mistake, I meant the rods, many times I have a student who will complain about a note not speaking only to find out that it is due to this...
