Erschallet, ihr Lieder BWV 172

Erschallet, ihr Lieder (BWV 172) is one of those early Bach cantatas which were often revived at Leipzig. The first performance of this work was given in Weimar 1714. Although only a few instrumental parts from this performance are extant, it may be assumed that at that time the cantata already had the form familiar to us from its first Leipzig revival. It was given in C major (church pitch, corresponding to D major in chamber pitch), and the first number was intended to be repeated at the end of the work.
