Armoris Quartet


The Armoris Quartet is a classical string ensemble with four high school musicians from the Pittsburgh Youth Symphony Orchestra (PYSO). The group earned the 23-24 Montgomery Fellowship Award with sponsorships from Chamber Music Pittsburgh and coachings with the Pittsburgh Symphony Orchestra violinist Jeremy Black. Though the group formed recently in the summer of 2023, they still featured on the WQED-FM Radio and highlighted numerous Gala performances. Through PYSO, they led their respective sections under Maestro Jacob Joyce and took part in the orchestra’s international tour to Portugal. Later this Spring, they will work in collaboration with the Pittsburgh Ballet School on Jessie Montgomery’s Strum and will also feature in the annual Tiffany Concert Series in April.
