4 stepper motors, 3D-printed PETG, Arduino board, electronic circuit.

Four stepper motors, typically used in digital fabrication to control precise movements, are used here as musical instruments. Programmed to rotate at specific frequencies, their rotation produces a quadraphonic mechanical choir. Each motor varies independently within a scale inspired by Gregorian chant. Together, they perform a machine improvisation, an endless generative chorus.
