The worst thing about being a character in the party scene of the Nutcracker is that the music gets stuck in your head. For many weeks on end, for hours at a time, we rehearse the party scene. The dances are all cued by the music. So not only do we have to listen to it, but we have to associate where we are on stage and all of the different dance moves to it.
I think the only way to flush out the constant music playing in my head is to replace it with other music.
I listened to "Guilty of the Crime" which is on the Eagles "Long Road out of Eden" CD and it did a pretty good job. Its catchy. Other music would probably work just as well, but I don't have a lot of time to listen to music.
