text: Since 1975, it has usually been assumed that Bach's St Matthew Passion was first performed on Good Friday 11 April 1727, although its first performance may have been as late as Good Friday 1729, as older sources assert. The performance took place in the St. Thomas Church (Thomaskirche) in Leipzig. Bach had been Thomaskantor (i.e., Cantor, and responsible for the music in the church) since 1723. In this version the Passion was written for two choruses and orchestras. Choir I consists of a soprano in ripieno voice, a soprano solo, an alto solo, a tenor solo, SATB chorus, two traversos, two oboes, two oboes d'amore, two oboes da caccia, lute, strings (two violin sections, violas and cellos), and continuo (at least organ). Choir II consists of SATB voices, violin I, violin II, viola, viola da gamba, cello, two traversos, two oboes (d'amore) and possibly continuo.
  Funeral cantata for Köthen (BWV 1143, previously 244a)
  Klagt, Kinder, klagt es aller Welt, BWV 244a, a cantata of which only the text is extant, was performed 24 March 1729 in Köthen at a memorial service held some months after the death of Leopold, Prince of Anhalt-Köthen. The music of the cantata consisted largely of music adapted from the St Matthew Passion.
