Chorale motet
The chorale motet was a type of musical composition in mostly Protestant parts of Europe, principally Germany, and mainly during the 16th century. It involved setting a chorale melody and text as a motet.
Stylistically chorale motets were similar at first to motets composed in Catholic countries, and made use of the full range of techniques of Franco-Flemish polyphony. In the earlier period, the chorale was typically used as a cantus firmus, fairly easy to hear, with other lines either weaving in and out contrapuntally around it, or following along in the same rhythm in an entirely homophonic style. Later in the century, especially around 1600, the successive verses of the chorale were used to begin imitative sections in a fugal style. Shortly after 1600 the form began to disappear, overtaken by newer forms based on Italian (especially Venetian) models: the chorale concerto, and later the chorale cantata. The chorale cantata was to become the most substantial of the descendants of the chorale motet, and eventually culminated in the work of J.S. Bach.
