CHAPTER 40. Johann Sebastian Bach: Vocal Music in Leipzig.
Johann Sebastian Bach:
Vocal Music in Leipzig
Bach moved to Leipzig in 1723 where he remained until his death in 1750. There he assumed the position of cantor (director of church music) at St. Thomas Church. Among his duties, those of organist, music teacher, and musical director in four churches in the city.
The typical structure of choral melodies is AAB. In the case of the choral Wachtet auf, the musical structure consists of seven phrases unfolding in a pattern AAB, specifically A (1,2,3), A (1,2,3), B (4,5,6,7).
Choral cantata: a sacred vocal genre that employs the text and melody of a preexisting Lutheran choral in all or several of its movements. In Bach’s choral cantata Wachtet auf, ruft uns die Stimme (BWV 140), the choral tune appears in the first, fourth and seventh movement.
