CYCLES OF HEALING


A five-channel composition developed during a residency at the Centre for System Modelling and Quantitative Biomedicine, University of Birmingham (Jan. 2020–21). The composition will be showcased both physically, at Centrala Birmingham in early 2021, and digitally, via an online exhibition. A series of online talks will accompany the shows.

Cycles of Healing is an evolving composition for five voices based on the research ‘Dynamic responses of stress hormones and inflammatory mediators following heart sugery’ by Daniel Galvi, Eder Zavala, Jamie Walker, Ben Gibbison (October, 2020).

The composition is generated in real time and evolves in a recursive trend. Each of the five voices behave independently, however, the behaviour of one affects the others. Consequently, the system slowly moves from states of instability (or inflammation) to states of harmony (or healing). The result is a self-sustaining compositional organism, whose continous cycles of instability and harmony structure the piece.

The graphic score illustrates the relationship between each voice. The hormones ACTH and Cortisol make up the harmonic axis of the piece, oscillating at 110hz. The outer triangle (Speakers Array) is made up of the inflammatory mediators TNF-α and IL6 and an Inflammation voice. During the period of a cycle, the outer triangle moves from dissonance towards consonance with the harmonic axis.
