Pyxis Piano Quartet

Founded in 2009, Pyxis Piano Quartet – a vibrant musical presence in the mid-Atlantic region – has become known for compelling, engaging and informative performances. Their concerts feature chamber music works from the sonata, duo, and trio repertoire as well as traditional and contemporary masterpieces for piano quartet. This season opens their second decade as artists-in-residence at the Delaware Art Museum and part of the Performance Series.

Pyxis has been heard to great acclaim along the East Coast in concerts from Virginia to Pennsylvania. Music critic Christine Facciolo writes that “balance, superb intonation and sensitive interpretation characterized [their] performance.” This season they will also appear in Market Street Music’s Festival Concerts Series (in Wilmington) and at The Woodlands, a historic mansion in West Philadelphia.

Recent performance highlights have included return engagements at the German Society of Pennsylvania (Philadelphia); the Newark (DE) Free Library; “Celebrate the Arts” series at Doylestown Presbyterian Church (PA);  the Kent Chamber Music Series (MD); Saint Monica’s Church (Berwyn, PA); and Smyrna Opera House (DE). The ensemble also made debut appearances in the Cultural Center at the Havre de Grace Opera House (MD) and the Annie M. Gaul Concert Series at St. John’s (Hain’s) Church (Wernersville, PA). Other notable performances include the Delaware Symphony’s Champagne Chamber Series at the Hotel duPont Gold Ballroom; Concerts on the Square at Holy Trinity Church Rittenhouse (Philadelphia); a benefit for the Harmony for Peace Foundation; and recitals as featured artists at the Delaware Chamber Music Festival and at Villanova University.

Pyxis believes in the importance of the music of our time and has collaborated with regional composers including Ingrid Arauco, Chuck Holdeman, and David Schelat. The ensemble’s violinist Luigi Mazzocchi has arranged works for Pyxis, which also delights in working with esteemed musical guest artists. Past guests have included artist faculty members from the University of Delaware, James Madison University, Pennsylvania School of the Arts, and the College of New Jersey, as well as members of the Philadelphia Orchestra, Metropolitan Opera Orchestra, Chamber Orchestra of Philadelphia, Pennsylvania Ballet Orchestra, Arkansas Symphony, Delaware Symphony, Relâche Ensemble, Serafin String Quartet, and Copeland String Quartet.

The musicians of Pyxis are committed educators. As private instructors they have a significant impact on their community, reaching over 80 students on a weekly basis. The ensemble has performed and coached sectionals and chamber music for the Delaware Orchestral and Chamber Music Institute and the American String Teachers’ Association Festival in Washington Township, NJ. They also have presented educational concerts at the Delaware Art Museum, Wilmington Montessori School, Saint Monica’s School, and in southern Delaware under the auspices of Coastal Concerts, Inc.

The group takes its name from the Pyxis constellation, also known as the Mariners’ Compass, whose symbol is the compass rose. The points of the compass rose represent the new artistic directions that the group explores together while recognizing the differing backgrounds and experiences of its four musicians.
