A chorale cantata is a church cantata based on a chorale—in this context a Lutheran chorale. It is principally from the German Baroque era. The organizing principle is the words and music of a Lutheran hymn. Usually a chorale cantata includes multiple movements or parts. Most chorale cantatas were written between approximately 1650 and 1750. By far the most famous are by Johann Sebastian Bach, especially the cantatas composed in his second annual cycle of cantatas, started in Leipzig in 1724.
