I find it annoying when the audience claps durring difficult moves like fouettes. They're hard enough to while concentrating, but when it is thrown off by appplause, it's distracting. Its alright to clap AFTER the dancer is finished them, but not durring. And the most obvioius pet peeve of all CELL PHONES!! Is it so difficult to turn off the phone before the show starts? And if you absolutly have to leave it on, then at least put it on vibrate and take it outside when it rings. It'a a nuisance to both the dancers and the rest of the audience.
