Bach’s sacred cantata, Nach dir, Herr, verlanget mich (BWV 150), was composed for an unknown occasion. The librettist is also unknown. Bach’s original manuscript is lost.
Nonetheless, scholars say that it may be Bach’s first cantata, composed in 1707 in Arnstadt, where he was organist. The scoring is for a small ensemble of two violins, bassoon and continuo, plus four vocal parts.
Johannes Brahms adapted the bass line of the closing chaconne of this cantata for the theme of the finale of his Symphony No. 4. Interestingly, Bach may have borrowed the ground bass line from Pachelbel!
