The St Matthew Passion, BWV 244, (German: Matthäus-Passion), is a musical composition written by Johann Sebastian Bach in 1727 for solo voices, double choir and double orchestra, with libretto by Picander (Christian Friedrich Henrici). It sets chapters 26 and 27 of the Gospel of Matthew to music, with interspersed chorales and arias. It is widely regarded as one of the masterpieces of classical sacred music...
Most of us come to the Saint John Passion knowing the Saint Matthew Passion first. The bigger and more elaborate Saint Matthew, which came along three, or possibly five years later (there is controversy about the date), has tended to cast a shadow in which the earlier work is swallowed up, and this has been so ever since Mendelssohn's Saint Matthew performance in 1829 marked the beginning of the public rediscovery of J.S. Bach. (The professionals had never forgotten.) But if the Saint John is smaller in scale than the Saint Matthew, it is hardly the lesser work in quality, though it would of course be silly to claim that the master of the Saint Matthew Passion had not learned from the experience of setting Saint John. But the most interesting differences between these two towering attestations of faith are differences in intention. Read Matthew 26-27, Mark 14-15, Luke 22-23, and John 18-19, and you get four tellings of the last days in the life of Jesus that differ in tone, emphasis, and detail…
Bach's St Matthew Passion is almost always described as a double-choir composition for two choirs and two orchestras. Two large ensembles play in dialogue, and the score presents a symmetrical structure. The scoring of the two groups of singers and players is identical, and each ensemble has four soloists for the arias. On the stage one often sees two equal groups of singers, and an orchestra likewise divided exactly into two. The Evangelist and Jesus are often the only exceptions to this impressive symmetry.
