Franz Joseph Haydn’s 100th Symphony - the so-called Military Symphony - was produced at a time when the composer was under a ton of pressure to compose his next great masterwork. This was during a second visit to London near the end of his life, and of course Haydn was up to the task of delivering another great piece of music to his audience. In this work, concertgoers heard, for the first time in a symphony, the use of percussion instruments like the triangle, hand cymbals, and bass drum. Tune in for the Military Symphony tonight at 7: our Evening Masterwork on Classical WSMR 89.1 and 103.9.
