Aria 'Erbarme Dich, mein Gott'

he St Matthew Passion (German: Mattheus-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 chapters 26 and 27 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 classical sacred music. The original Latin title Passio Domini nostri J.C. secundum Evangelistam Matthum translates to "The Passion of our Lord Jesus Christ according to the Evangelist Matthew Originally for alto voice, violin solo and string orchestra. The arias are in da capo format (ternary form). "Erbarme dich", for alto, and "Mache dich, mein Herze, rein", for bass, are examples of such arias in Part Two of the oratorio. In these movements the singers are accompanied by one or a few solo instruments and continuo, occasionally completed by other instrument groups of the orchestra.
