On a table is an old oscillator, stable at a 479.5 Hz frequency, connected to a speaker and a 480 Hz tuning fork. When the tuning fork is randomly struck by a solenoid, a beating pattern appears. Then the audience hears the friction between the two oscillations, the friction between the electronic and the acoustic, the friction between different periods of the history of sonic research. This humble piece is an homage to sound artist Alvin Lucier who worked extensively with oscillators, and physicist Hermann von Helmholtz who used the tuning forks for sound analysis and who was among the first to theorize on the beating patterns between frequencies.
