Church cantatas of Bach's third to fifth year in Leipzig

[4] Together with his assistants he provided performance material for at least 18 of these cantatas, for which the Leipzig premieres are known, from Purification (2 February) to Trinity XIII (15 September) 1726.

Through an erroneous attribution to the former the cantata Denn du wirst meine Seele nicht in der Hölle lassen, JLB 21, is also known by a BWV number.

Historians of music studying the cycle have noted a greater use of solo organ parts, speculated to have been played by Bach or his son [WHICH ONE?

The librettos of the church cantatas presented for the first time in Leipzig during Bach's third to fifth year in that city have a diverse origin.

[28] In 1728 many of the librettos of cantatas associated with Bach's third to fifth year in Leipzig were grouped in a single publication by Christoph Birkmann.

[30] The period covered by the booklet included the feasts of St. John and Visitation: The musical settings of these librettos as performed in Leipzig on these days have not been recovered.

Recent recovery of a copy of Birkmann's 1728 libretto cycle seems to suggest Welt, behalte du das Deine and Ich kann mich besser nicht versorgen for the first and the second Sunday after Easter respectively.

The 18 cantatas by Johann Ludwig Bach that were performed in Leipzig from Purification to Trinity XIII 1726 had a libretto from this cycle, as well as seven of the cantatas composed by Johann Sebastian Bach which were presented for the first time from Ascension to Trinity XIV 1726.

[4] Further cantatas with a libretto from the Meiningen cycle may have been presented in Leipzig in 1726, for instance on the fourth and the ninth Sundays after Trinity.
