The Chorus of the Naples San Pietro a Majella Conservatory is made up of singers from the conservatory, whether vocal students or instrumentalists, with a repertoire that ranges from the baroque to the contemporary. Important appearances have included the festival concert at the dedication of the Sala Scarlatti in the conservatory itself, and at the Cologne Philharmonic. There was a notable performance of church music with works by Duke Ellington and in 2003 a performance at the Vatican, televised internationally.
