Un Sospiro

“Instrument for live performance on piano and lights.”
MIDI data from the digital piano controls real-time LED visuals based on a particle system with springy underdamped physics. Keys to the left of a division on the keyboard produce sinusoidal low-frequency oscillations that modify the behavior of all particles, while other keys emit new particles following an intuitive mapping between pitch, color, and angle.”

“The chaotic combination of the particle emitters, oscillators, and physics can produce complex and nuanced visuals that are completely under control of the performer. After learning the instrument, a performer may intonate emotion into light and sound simultaneously.”
