TOTTERING STEPS by MINORU SATO & ASUNA

A
“Natural Fluctuation By 8 Entangled Tones From 4 Keyboards And 4 Resonators”
Equipment:
Casio SA-5, keyboard tone_1
Casio DJ-1, keyboard tone_2
Casio SK-1, keyboard tone_3
Yamaha reface YC, Keyboard tone_4
Air column resonator_1
Air column resonator_2
Helmholtz resonator_1
Helmholtz resonator_2

Apparent peak frequencies:
220hz constant resonance, caused by Helmholtz resonators
330hz entangled resonance, beating on around 0.98s
498hz entangled resonance, slowly beating on around 270s caused between air column resonators and keyboards
530hz entangled resonance, slowly beating on around 110s caused between air column resonators and keyboards
660hz entangled resonance, rhythmic pattern by beating on around 1.90s

B
“Giuseppe Tartini Entangled Sleng Teng”
Combination tones from the following sound sources:
Korg synthesizer playing Sleng Teng by varied speed
Air column resonator_1
Air column resonator_2
Helmholtz resonator_1
Helmholtz resonator_2
Extracted resonance frequencies — 494hz, 679hz, 1352hz, 2600hz, 4800hz — from a combination of acoustics caused between keyboard and resonators
1290hz sine wave

"Sato and Asuna are Japanese musicians both working on production of electronic music from keyboard instruments and non-specifically musical scores. Their two pieces remind me, in parts, of a futuristic and broken cuckoo clock, and also of being aussalted by a fluorescent desk lamp. " Byron Coley, The Wire (2019)
