How did the Baroque vocal-instrumental concerto influence the German cantata?

The Baroque vocal-instrumental concerto significantly influenced the development of the German cantata by providing a foundational model for combining vocal soloists, choirs, and instruments.12

The vocal-instrumental concerto, which emerged in the late 16th and early 17th centuries, was characterized by the concertato style—a principle of contrast between different groups of performers, such as soloists versus choirs or vocalists versus instrumentalists. German composers, such as Michael Praetorius and Heinrich Schütz, adopted these Italian techniques for Lutheran religious music.231

A key aspect of this influence was the fusion of these concertato techniques with the Protestant chorale, or hymn. By incorporating the chorale into works that already utilized the concerto's massive sound oppositions and subjective soloistic intensity, German composers created a direct ancestor to the church cantata. As the vocal-instrumental concerto evolved, it eventually gave way to the cantata by the mid-17th century, though the cantatas of composers like J.S. Bach continued to reflect the structural and stylistic echoes of the earlier concerto tradition.12
