Samantha Wittchen is a Philadelphia-based performing harpist, teacher, and arranger. She is most adept at showcasing the harp’s versatility by using it in contexts where it is least expected. You may just as easily find her playing at a Beatles tribute show at Johnny Brenda’s, with a robot at Philly Tech Week, or in the orchestra for The Nutcracker. She loves creating opportunities for people to experience the unique beauty of the instrument in a fun, welcoming environment.

Samantha has performed with the Allentown Symphony, the Lehigh Valley Chamber Orchestra (LVCO), the Pottstown Symphony, the Schuylkill Symphony and the Northeastern Pennsylvania Philharmonic. She has also performed in studio orchestras for such recording artists as McCoy Tyner, Olivia Newton-John and Connie Francis, as well as popular touring shows like Video Games Live and A Salute to Vienna. She also appeared in the 2009 movie Law-Abiding Citizen, starring Jamie Foxx.

Samantha studied harp performance at the Eastman School of Music in Rochester, NY and then at the University of Virginia while completing a degree in mechanical engineering. Since 2005, she has been the professional associate for harp at the University of Pennsylvania, and in 2015, she launched Philly
Music Lab (PML) with violinist Alexandra Cutler-Fetkewicz. Through a mix of community building and music contracting, PML specializes in connecting diverse, cross-genre musicians to new audiences and each other with the goals of promoting and supporting high-quality live music throughout the Philadelphia region.
