Perna found herself drawn to viola performance, and especially chamber music, because of the collaborative and democratic nature of the music-making process.
The Esterhazy Quartet, the string quartet with whom Perna performs chamber music, focuses particularly on work from contemporary living composers. The Esterhazy Quartet established residency at the Berklee College of Music in Boston six years ago, where they experience the magic of the collaborative process while working with the best student composers.
