Johann Sebastian Bach's 'O Lamm Gottes unschuldig (IV), BWV 1085' is a chorale cantata that was composed in the early 18th century. The piece is based on the hymn 'O Lamm Gottes unschuldig' by Nikolaus Decius, which was written in the 16th century. The cantata was likely composed during Bach's time as the court organist in Weimar, between 1708 and 1717. The cantata is divided into six movements, each of which is based on a different verse of the hymn. The first movement is a chorale fantasia, in which the choir sings the first verse of the hymn while the orchestra provides a complex and intricate accompaniment. The second movement is a duet for soprano and alto, in which the two voices intertwine and complement each other in a beautiful and delicate manner. The third movement is a recitative for bass, in which the soloist reflects on the sacrifice of Christ and the redemption that it brings. The fourth movement is a chorale setting of the third verse of the hymn, in which the choir sings the melody in unison while the orchestra provides a simple and understated accompaniment. The fifth movement is a duet for tenor and bass, in which the two voices engage in a lively and playful dialogue. The final movement is a chorale setting of the sixth verse of the hymn, in which the choir sings the melody in unison while the orchestra provides a majestic and triumphant accompaniment. Overall, 'O Lamm Gottes unschuldig (IV), BWV 1085' is a beautiful and complex work that showcases Bach's mastery of both choral and instrumental music. The piece is characterized by its intricate counterpoint, rich harmonies, and expressive melodies, and it remains a beloved work in the choral repertoire to this day.
