Ensemble City has three rehearsal rooms: City 1, City 2, and City 3. Various classes, primarily ensemble classes, are taught here; however, the rooms are rented out to students whenever they are not scheduled for use.

Furthermore, the Ensemble City Office Wing, which is adjacent to the Rehearsal Wings, houses various facilities such as a musical instruments room, teachers’ lounge, storage room for music scores, and offices. Ensemble City provides everything necessary for giving ensemble classes, all in one place.
