Philadelphia Youth Orchestra

The Philadelphia Youth Orchestra (PYO) is an American youth orchestra that is located in Philadelphia, Pennsylvania. The orchestra's current music director is Louis Scaglione.

Regarded as one of the best youth orchestras in the United States, this orchestra works with a "companion ensemble," the Philadelphia Young Artists Orchestra (PYAO), the lower version of PYO, which was established in 1996, and Bravo Brass, a brass ensemble that was founded in 2003.

In 2007, another group, Philadelphia Region Youth String Music, (PRYSM), was added to the program as a string music education ensemble. In 2016, a new companion ensemble, the (YMDO), or Young Musicians Debut Orchestra, was introduced.
