Instrument Building + Performance Practice

Instrument building and performance form an ongoing part of my practice. This work moves between electronics, sculpture, sound, and live performance, using the design and calibration of instruments as a way of thinking materially. Rather than treating an instrument as a fixed tool, I approach it as a system that develops its own tendencies through tuning, use, instability, and repetition.

The instruments are built through a process that combines circuit design, prototyping, testing, and sculptural decision-making. Their form is not separate from their behaviour: enclosure, interface, tactility, fragility, and gesture all shape how sound emerges. In performance, these systems become a way of working with uncertainty, drift, and relation between body, machine, signal, and environment.

This strand of the work includes solo improvised electronics, live audiovisual performance, and collaborative projects such as SPIT. Across these contexts, I am interested in how a custom-built instrument can carry memory, bias, resistance, and character, and how performance becomes a way of exposing those qualities in real time.

Instrument Builds

Hybrid FM Synth

A hybrid FM synth combining analog VCOs and VCA with an Arduino-controlled envelope generator and stretchy control interfaces.

The instrument is currently in a breadboarded, hot-glue phase. Ongoing experiments are focused on replacing pots with alternative variable resistors, developing wearable CV generators, and working out how these control systems can become more tactile, unstable, and performative.

The build also extends into hand-made sculptural patch cables, treating connection and signal routing as part of the instrument’s physical language rather than just utility.
