Long Waves And Random Pulses by Annie Gosfield published on 2017-01-12T03:08:53Z Composed by Annie Gosfield (2012, 13 minutes, for violin and tape) Recorded by Pauline Kim Harris at Harvestworks in 2016 Commissioned by Gaudeamus Muziekweek Long Waves and Random Pulses is a duet for violin and jammed radio signals. I composed and researched the piece at the American Academy in Berlin, using original recordings of jamming sounds that were used to block radio transmissions in Italy, Germany, and the Soviet Union in World War II. The violin merges and emerges, shifting from music, to noise, to pure signal while fading in and out of the sounds of intentional radio interference. The electronic backing track includes a repeated six-note figure that was drawn from original recordings of an Italian radio jamming device, a buzzing pitched pulse from a German jamming device, a quote from J. S. Bach’s Chaconne in D Minor as it could have been heard in a jammed broadcast, and many extended techniques that evoke the sounds of these otherworldly radio signals. The violin part alternates between virtuosic and textural playing, shifting between notes and noise. As for the title, Long Waves refers to the long wave radio frequencies that many of these interrupted signals were broadcast on. Random Pulses represents a method of radio jamming that uses a random pulse noise to override the program broadcast on the target radio frequency.
