About Us

Founded in 2006 by adventurous professional musicians in State College, Pennsylvania, we are five musicians on violin, viola, cello, oboe, and English horn. We perform a wide variety of styles ranging from early music to contemporary and popular music. World premieres and new arrangements keep us fresh. We are available for wedding ceremony music, background music for receptions, private parties, memorials, and more in Central Pennsylvania as a quartet, trio, duo or solo. A highlight in 2015 was a full program with jazz pianist Billy Childs and his band. 

Our Allegría String Quartet with Sally, Mark, Debbie and Jon clicked at our first reading of music by Cole Porter, Haydn, and Coldplay. Trained teaching artists Robyn and Debbie help guide our outreach work in concerts for new audiences. We are all enthusiastic teachers and enjoy sharing our love of music with new listeners of all ages. We like to explore the intersection of music with art, history, world culture, science, math at venues including libraries, parks, museums, hospitals, colleges, senior communities, coffee cafés, and distilleries.

In spring 2019 our Penn's Woods Music 4 Kids and  U were performed at Schlow Library, Bellefonte Children's Garden, Discovery Space, Holt Library, Bellefonte Art Museum, Palmer Art Museum and Millbrook Marsh Nature Centre. We are grateful for grant support from the PA Council on the Arts, the Music Performance Trust Fund, and the Music at Penn's Woods Festival and their generous donors.
