Listen to Haydn symphony No. 12 and say what was interesting about the sonata cycle. What should people listen for, and why should people listen to it. Only needs to be a paragraph or two.

Surprise Symphony, byname of Symphony No. 94 in G Major, orchestralwork by Austrian composer Joseph Haydn, so named for the “surprise”—a startlingly loud chord—that interrupts the otherwise soft and gentle flow of the second movement. The distinctive feature did not appear in the original score. Rather, it was added by the composer on a whim for the piece’s London premiere on March 23, 1792, and was retained in later performances.
