At 100 years old, the Portland Youth Philharmonic is the country’s oldest youth orchestra, with a rich and storied history. In the early 1920s a young classically trained violinist and teacher, Mary V. Dodge, conceived of what would become the Portland Junior Symphony. It formed in earnest after she convinced a renowned Russian conductor to take on the orchestra composed of students that she was teaching in her attic. The Oregon Historical Society is opening an exhibit on the PYP next month, which will chronicle its birth and achievements over the last century. Joining us are Musical Director David Hattner, PYP principal flutist Macy Gong and former PYP musician Tim McCarthy, who now plays with the National Symphony Orchestra.
