J. S. Bach (1685-1750)

Ich lasse dich nicht, du segnest mich denn

BWV Anh. 159

Motet for 2 choirs

The composer of this motet is unnamed in the original score, which was copied by Johann Sebastian Bach and his pupil Philipp David Kräuter about 1712/1713 in Weimar. Johann Sebastian Bach collected this manuscript in his "Alt-Bachisches Archiv", a collection of musical works of his predecessors. In the 19th century it was attributed to his uncle Johann Christoph Bach. Present-day musicologists lean towards Johann Sebastian's authorship instead. They definitely consider that Johann Sebastian Bach is at least the author of the 2nd part (bars 84-116) or of the complete motet. The final chorale, a chorale harmonization by Johann Sebastian Bach (BWV 421), is probably an addition by Johann Gottfried Schicht, the editor of the first printing (Leipzig 1802).
