about

This project explores simple ratios and the attentional span of our listening experience as it denotes all rhythmic levels (beats, pulse and meter) at once, encompassing rhythmic entrainment, pitch perception and colour saliency, and their interplay.
As my biggest interest is based in musical cognition and our perception of stimuli, mainly, how do we hear rhythm and pitched intervals? and how can I use these notions and aesthetics for artistic expression and exploration?
The inspiration for the piece comes from the Rhythmicon, which was originally commissioned to Henry Cowell from Léon Theremin, in an effort to create an electronic device which uses various simple and compound divisors which spit out pulses of tones at regular intervals, based on the simple mathematic ratios of the Euclidean Mathematica.

Basing the rhythmic divisions on the ratios of Euclidean math, creating the first “harmonic rhythm scale” was where I started my exploration, further accelerating the wavelength ratios into the pitch domain, as well as logarithmically extending them upwards, in order to reach the visible light spectrum of colour.
I was fascinated with the beats played one atop the other, similar to the overtone series, as the exclusion of a salient beat marker, and inter onset intervals, becomes increasingly smaller.

The basic underlying physical principles of rhythm, pitched intervals and colour overlap greatly
because both music and color are manifestations of wave phenomena.
In particular, commonalities exist with respect to the production, transmission, and detection of sound and light. Some wave phenomena are relatively easy to demonstrate for sound but not for light, and vice versa.

In this composition, the chromatic scale extending from 432Hz is explored; The beat ratios is equivalent to the ratio between the two pitched “bleeps”, as well as the ratio between the two colour gradients.

This project is an extension of my fascination of creating audio-visual relationships based on physics and science, including our perceptual models of cognition.
