Vereinigte Zwietracht der wechselnden Saiten (United
discord of quivering strings), BWV 207,[a] is a secular
cantata composed by Johann Sebastian Bach and first
performed on 11 December 1726 in Leipzig.
Bach composed this cantata to celebrate the appointment
of Gottlieb Kortte as professor of Roman Law at Leipzig
University. The librettist of the work is unknown: it
may have been Picander, who had been providing libretti
for Bach from at least the previous year when they
collaborated on another academic cantata Zerreißet,
zersprenget, zertrümmert die Gruft, BWV 205.
Bach incorporated music from his first Brandenburg
Concerto, which was composed years earlier. The third
movement of the concerto is used for the opening chorus
with trumpets replacing the concerto's horns and some
of the instrumental music given to the choir.
There is a related work Auf, schmetternde Töne der
muntern Trompeten, BWV 207a.
The cantata features four solo singers: Glück
(soprano), Dankbarkeit (alto), Fleiß (tenor), and Ehre
(bass). It is also scored for four-part choir, three
trumpets, timpani, two flutes, two oboes d'amore,
taille, two violins, viola, and basso continuo.
