The three-story building includes a two-story, 3,500-square-foot, acoustically isolated Lee Rehearsal Room with soaring 30-foot ceilings and equipment for professional-quality audio recordings. An 800-square-foot jazz studies studio is one of several specialized teaching facilities in the Effron Music Building. A large number of acoustically advanced practice rooms and teaching studios are located on the second and third levels, featuring brand new pianos from Steinway & Sons. The practice rooms and teaching studios are suspended from the roof structure to assure sound isolation. Each teaching studio has room for a teacher, student and up to two grand pianos. Several rooms also include audio recording and playback systems.
The Princeton University Orchestra, Princeton University Sinfonia, Jazz at Princeton University, piano lessons, large-instrument lessons, and some small-instrument lessons are housed in the Effron Music Building. Graduate programs, academic classes, the Princeton University Glee Club, student ensembles, vocal lessons, and some small-instrument lessons continue to take place in the Woolworth Center.
