Symphony

Steak sizzling on a grill at Pat's King of Steaks. A chorus of birdsong at the Philadelphia Zoo. These are just a few of the hundreds of sounds composer Tod Machover collected from people who live here for a unique musical profile being performed by The Philadelphia Orchestra on April 5, 6, and 7 at the Kimmel Center in Philadelphia.

The symphony, as we know it today, underwent major changes from the end of the 18th to the late 19th century. As WRTI’s Susan Lewis reports, two symphonies from two composers in Vienna during that time illustrate the range of the form.
