Nach dir, Herr, verlanget mich, BWV 150 [SEP] History and text
The cantata is, as John Eliot Gardiner notes, "generally accepted to be Bach's very first church cantata." Gardiner conducted in 2000 the Bach Cantata Pilgrimage and performed the cantata in the church for which it was then probably composed, at Bach's time called "Neue Kirche" (new church), now the Johann-Sebastian-Bach-Kirche. The libretto alternates between biblical verses and free contemporary poetry, which is common in Bach's later cantatas, but rare among his early cantatas. The text of movements 2, 4, and 6 are selected psalm verses, . The author of the poetry is unknown. On the basis of the text, it has been suggested that the work was written for a penitential service.
