In 2012, I designed a visual score/animation comparing rival pitches 432 Hz and 440 Hz part of a multimedia presentation, titled “Pitch Battles” at Machine Project in Los Angeles and California State University in Monterey Bay. The animation, titled “Digital Macrame” will be projected on the Manhattan Bridge Anchorage in conjunction with “DUMBO Glow” this Thursday December 19th and Friday the 20th from 5-9pm and curated by Leo Kuelbs and John Ensor Parker. The animation is set to Wagner’s Das Rheingold Act 1: Prelude and pitch-altered by Chris Kallmyer.
More about the original multi-media performance:
In overlapping performances, Colin Dickey, Nicole Antebi and Chris Kallmyer will explore the difference between two rival pitches, 440 Hz and 432 Hz: Colin Dickey will trace the history of the war for correct musical tuning, a debate that’s raged for two centuries and has involved the Nazis, French government, BBC, Lyndon Larouche, and new age practitioners. Responding to the phenomenon of radial pattern formation by sound frequencies or Cymatics, Nicole Antebi will accompany the talk and performance with a video tinkering with the shape of sound. Additionally, Chris Kallmyer will accompany the talk sonically, creating an multi-channel environment of competing tonal systems and real-time examples of pitch-altered recordings of Wagner, sine tones, and live instruments.
