Walther sets three verses of this chorale. The first verse is for manuals only. The cantus firmus is in the soprano played by the right hand along with an additional accompanying alto voice. The left hand maintains a constant flow of 16th notes throughout.
The second verse is also for manuals only with the cantus firmus in the soprano. The flow of 16th notes also is present here, but switches back and forth between the alto and bass lines.
The third verse is for manuals and pedal with the cantus firmus in the pedal.
