As well as the Mass in B minor, there are four further, shorter mass compositions by Bach, the so-called Lutheran or Kyrie-Gloria masses. Despite their high musical qualities, they are often overshadowed by other church works by Bach. With their six-movement structure (up to the "Cum sancto spiritu") they had their specific liturgical position in church services of the time of Bach. The masses largely comprise parodies, with the original music mainly taken from cantatas which Bach sometimes considerably reworked in his well-known style according to the new context of the work. Ulrich Leisinger has edited the four works for Carus in new critical editions.
