This composer used thirteen repetitions of a passus duriusculus, or chromatic fourth, in E to evoke Christ’s suffering in one piece’s “Crucifixus” section. That work by this composer, which is often referred to by its key, features a Credo section titled “Symbolum Nicenum.” This composer’s cantata Schweigt stille, plaudert nicht (“sh’vyte SHTILL-uh, PLOW-dert nick’t”) is humorously dubbed the Coffee Cantata. (10[1])An 1829 performance conducted by Felix Mendelssohn revived interest (10[1])in this composer’s St. Matthew Passion. This composer of a Mass in B Minor wrote a collection of 24 preludes and fugues to show off (10[1])a new tuning system. For 10 points, name this German Baroque composer of the Well-Tempered Clavier. ■END■ (10[1])
