In the MASS MoCA portion of this multi-part project, Harmonic Bridge, low sounds roll and drone under the Route 2 overpass half a block from MASS MoCA. Entering the space under the bridge, one becomes aware of a turning eddy of sound in the midst of intersecting streams of traffic. Cars pass by heading north or south on Marshall Street and east or west on the Route 2 bridge, but this linear motion is counterpoised by a rolling humming in the key of C, as calming as the rhythm of ocean waves. Although cars stream by, pedestrians lose the impetus to move forward, momentarily derailed by a cool pool of sound with its mysterious, chant-like hum. Harmonic Bridge presents an aural cross-section of North Adams, a slice of the city in the key of C, comprised of the fundamental note and its overtone series.
