The assignment compares the first performances and characteristics of J.S. Bach's Cantata No. 140 Wachet Auf and G.F. Handel's Messiah, two famous pieces of music. Both were performed for the first time in the 18th century, with Messiah being revised by Mozart. The comparison highlights similarities such as the use of SATB choir and solo, violins, viola, oboes, and continuo, while also noting differences like the number of movements (53 in Messiah vs. 7 in Wachet Auf) and the types of instruments used.
