 Bach structured the cantata in six movements, four movements of alternating arias and recitatives, then the voices united in a duet and finally a closing chorale. He scored the intimate dialogue for soprano and bass soloist, a four-part choir only in the chorale, and a Baroque instrumental ensemble of oboe (Ob), two violins (Vl), viola (Va) and basso continuo. The duration is given as 22 minutes.
