Its structure combines rigorous counterpoint with textual interpretation, featuring an unusual bass-led chorale fantasia. The work later influenced thematic material in Bach's Christmas Oratorio.
This aria from Bach's cantata BWV 135 exemplifies his dramatic choral writing during the Leipzig period. Featuring vigorous string motifs and a commanding bass solo, the music depicts the expulsion of evil forces through jagged melodic contours spanning nearly three octaves. The cantata belongs to Bach's second chorale cycle, showcasing his fusion of sacred text with Italian concerto elements. The original scoring included cornett and trombone to reinforce theological symbolism.
Bach's cantata BWV 135 represents the pinnacle of Lutheran church music, featuring a remarkable chorale fantasia where the bass carries the cantus firmus instead of the traditional soprano. The opening movement contrasts delicate instrumental trios with powerful vocal polyphony, dramatically broadening the tempo on the words "that I may live forever." Bach would later reuse this same melody in his Christmas Oratorio and St Matthew Passion, demonstrating its significance in his compositional output.
