My orchestra stand partner mentioned that when she was in Russia she attended several concerts (as musicians tend to do in foreign countries) and noticed that much of the audience would spend intermission walking in a circle around the lobby. How odd, I thought, I am certainly going to look that one up on the Internet! Surprisingly, the only real hit popped up from my frequent haunt, Ask Metafilter. Someone had read about the observation in Fred Plotkin’s “Opera 101” that German audiences will walk in a circle in the lobby. Interesting.
