Ellen Reid SOUNDWALK is a free, GPS-enabled work of public art that uses music to illuminate the natural environment. Created by Pulitzer Prize-winning composer and sound artist Ellen Reid, the experience is guided by the listener: the path you choose dictates the music you hear, and no two visits will be exactly the same. As you walk, various musical “cells,” as Ms. Reid calls them, are triggered by your location. So each walk results in a different piece. The music is designed to continually evolve as the you progress through the park in real time as opposed to a set playlist. Individual segments last 2 to 16 minutes, but with the whole experience is built on what Reid calls “orbiting soundscapes” and “cascading cycles,” there are almost endless possible variations. The music shifts to reflect changes in your location, the landscape, and famous landmarks and structures. In wooded areas, music is dense and rhythmic, in fields, the music is spacious, custom-tailored to the landscape of your park or public space. Localized sound elements including recorded works by local orchestras, ensembles, choirs, and spoken word can be incorporated into each new version. Ellen Reid SOUNDWALK was co-commissioned by the New York Philharmonic, Saratoga Performing Arts Center, Wolf Trap Foundation for the Performing Arts, Mann Center for thePerforming Arts in association with The Fairmount Park Conservancy, and the Britt Festival Orchestra.
