Unlike most musicians in the Philadelphia Orchestra, Angela Zator Nelson of Media does not play one instrument such as the violin or cello. Instead, as a percussionist, she is adept at playing an array of instruments, even though her primary one is the timpani.Drums, cymbals, xylophone, vibraphone, marimba, glockenspiel, tambourine, cymbals and castanets are all in the repertoire of the Delco percussionist.
