This work sists halfway between Bach’s motets, and his cantatas. It is a one-movement work based on a chorale cantus firmus. We think it is a funeral work dating from 1737, and used in 1740 at the funeral of the Governor of Leipzig, Count Joachim Friedrich von Flemming.
It exists in two versions – one with wind and no strings, using cornetts, trombones (sackbuts), organ, and two ‘litui’ which are thought to be a J-shaped Roman(-inspired) trumpet/horn instrument. The second is for the litui with strings, continuo, and optional oboes and bassoon.
