The Cappella Musicale Pontificia Sistina is the papal choir based in the Sistine Chapel in Vatican City, with origins tracing back to the Renaissance and a formal role as the Vatican's liturgical choir. Specialising in sacred choral repertoires such as Gregorian chant, Renaissance and Baroque polyphony and a cappella liturgical music, it has maintained a repertoire and institutional role that evolved to incorporate later sacred compositions while influencing liturgical music practice within the Catholic Church.
