 There are some cantatas that belong to one of both cycles, but not to the other, for instance the chorale cantata for Trinity 1727 replaces the Trinity cantata of the second cycle composed in 1725.Also, some cantatas traditionally seen as belonging to the chorale cantata cycle are not chorale cantatas in a strict sense, for instance the cantata for the Sunday between New Year and Epiphany added to the chorale cantata cycle in 1727.Neither the second cantata cycle, nor the chorale cantata cycle are complete annual cycles as extant.
