The St Matthew Passion, BWV 244, is a Passion, a sacred oratorio written by Johann Sebastian Bach in 1727 for solo voices, double choir and double orchestra, with libretto by Picander. It sets the 26th and 27th chapters of the Gospel of Matthew (in the Luther Bible) to music, with interspersed chorales and arias. It is widely regarded as one of the masterpieces of Baroque sacred music. Wikipedia
