The Walden School was co-founded in 1972 by David Hogan, Pamela Layman Quist, and Lynn Taylor Hebden following the death of Grace Newsom Cushman, the founder of the Junior Conservatory Camp (also commonly referred to as the "JCC").
In the Walden School's Musicianship Course students simultaneously learn singing, playing, writing, and improvising music.
More advanced classes take an open-ended approach, in that students are encouraged to compose any style they please while simultaneously receiving guidance from their composition teacher on orchestration and notation techniques.
The lab uses Apple Power Mac computers, each supplied with Digidesign Mbox hardware and Reaper software.
The Faculty Commissioning Project offers opportunities for collaborating with resident musicians and premiering new works.
