Johann Sebastian Bach composed the church cantata Ach Herr, mich armen Sünder (Ah Lord, poor sinner that I am),[1] BWV 135 in Leipzig for the third Sunday after Trinity and first performed it on 25 June 1724. It is the fourth chorale cantata from his second annual cycle, and is based on the hymn by Cyriakus Schneegass.
