This coming summer, I will be taking two vacations, both lasting around 7 days in length. I am not the type of person who can take a week off and come back relativity close to where they left off. If I don't play at all for a solid week, my lips don't buzz as freely or respond very accurately and generally there is a cut in range (temporarily) until the lips get used to buzzing again. I don't forget how to play- it's just as if my lips forget how to buzz properly and it takes a good 2-4 days of practice to get back on track.
I'm wondering what I can do while on these vacations to stay in the best shape (playing wise, that is). I would assume something that can be done is mouthpiece buzzing, but I was wondering if anyone has suggestions other than that (without bringing a horn obviously.. since most of the time spent staying in shape will be in a hotel room).
