The 12 vocal works on this new double CD with L'arpa festante follow without exception the type of the choral cantata "per omnes versus", i.e. a type in which (almost) all the verses of a chorale poem are set to music, and represent a representative cross-section of the most diverse composers. This genre is to be distinguished from a cantata with chorale, which is characterised by a mixture of different texts. It is also distinguished from the historically older chorale motet, which does without obbligato instruments, and from the chorale concerto, which is often through-composed. The "heyday" of the chorale cantata "per omnes versus" mentioned at the beginning lies in the period after the Thirty Years' War until shortly after 1700. After that, the chorale - including the chorale poem - loses its importance; it is only with Johann Sebastian Bach that the chorale is given a new, pre-eminent position in the church music of his time, albeit under changed stylistic conditions.
