The cantata BWV 155 is distinguished by its particularly chamber music-like character and instrumentation. After the introductory Accompagnato recitative, in which the soprano is expressively declaiming above an organ point on D, in the duet of the alto and tenor that follows the virtuosically written bassoon part is striking. The soprano aria "Wirf, mein Herze" ("Throw yourself, my heart") is marked with intensity by the gesture of a constant dotted rhythm.
