An offshoot of a course taught by Margarita Mazo, Rusalka has developed into a performing group, consisting of OSU students and faculty, as well as residents of the Columbus metropolitan area. Rusalka's repertory includes music from Eastern Europe, but its specialties are polyphonic singing and dance in Russian villages and Russian Orthodox chant. Village songs are learned by studying ethnographic filed recordings in various regions of Russia, with some help from transcription and transliteration. The performance on Saturday October 27 at the SEM 2007 was a reunion with several alumni, currently teaching at various schools.
