Several of you were asking me about what to do when your flute is slipping off your chin (especially in the heat of marching band). Check out the Lip Plate Grips at the music store. They are just a clear sticker that you put on the lip plate. Make sure to clean the lip plate before you use it. Yamaha puts out a package with several in it (I think it’s 15). The sticky on the back is not supposed to damage the finish of the flute. I know Carolyn Nussbaum carries them in her flute store, and I’ve seen them on-line as well. Hope that helps!
