Ear Worm...

I've had a fast and furious encounter with Lewis Carroll's famous poem JABBERWOCKY and have bits of stuck music -- fragments of rhythm, a few chord changes -- small bits all stuck and looping endlessly.  I sing it in my sleep.  I feel it in my body when walking.  I try to think of something else.  It's annoying.

I've encountered this many times, sometimes while rehearsing a piece intensively in an honor choir situation, but most often during the process of composing.  Maybe I'm working it out on a subconscious level.  Maybe it's just hopelessly stuck.  I'm singing it now...
