Orchestras everywhere love to talk about their commitment to music education. But the Pittsburgh Symphony Orchestra has taken the unusual step of adopting a specific school where the music program was in danger. Last year, Wilkinsburg High School didn’t even have enough instruments for the kids who had signed up for band. Then the PSO, which already had a relationship with the school, showed up and played a benefit concert, raising $17,000 for the music program. The orchestra is repeating the benefit this year, with the aim of solidifying music as a core component of the school’s curriculum.
