Bostons Chorus pro Musica was founded in 1949 by the late Alfred Nash Patterson, one of the most influential forces in choral music in New England, and quickly built a superb reputation for its professional-level musical standards and innovative programming. Over the years, these strengths have led to collaborations with such organizations as the Boston Symphony Orchestra, the Boston Philharmonic, the Pittsburgh Symphony Orchestra, the Rhode Island Philharmonic, Craig Smith and Emmanuel Music, and the Boston Academy of Music, as well as various opera companies including Boston Concert Opera, Opera Company of Boston, and Commonwealth Opera. The chorus has twice received Grammy nominations for recordings made with the Boston Symphony Orchestra on the RCA label. Chorus pro Musicas dedication to new and rarely performed choral music has resulted in numerous Boston premieres, several American premieres, and at least two world premieres ; the Poulenc Gloria and the Britten War Requiem. Chorus pro Musica continues to develop partnerships with such leading musical organizations as the Boston Philharmonic, Newton Philharmonic and the Boston Youth Symphony Orchestras. In 1998 we were proud to perform in the Lila York World Premiere of Boston Ballets Ode to Joy, a sweeping, impassioned new ballet set to the final movement of Beethovens Ninth Symphony. We have been proud to join the Boston Philharmonic in performances of Mahlers Eighth Symphony and, most recently, his Second Symphony.
