“Improvising Machine 7325: Inside My Trumpet, Again” places the audience inside a trumpet, exploring the instrument’s interior sonic world through an immersive human–machine improvisation system.

The work is built from an extensive sample library captured by placing microphones deep within the instrument. These samples document the mechanical sounds and actions of trumpet performance without the instrument being played traditionally—collections of the sound of valves descending, springs releasing, air being compressed and released by slides, valve caps loosening, spit-valve gurgles, and a range of non-tonal lip, air, and tongue sounds produced through the mouthpiece and leadpipe.

Twenty-eight autonomous virtual agents (“robots”) that I authored in Max/MSP and host in Ableton Live inhabit a 360-degree ambisonic field surrounding the audience. Each agent draws from its own subset of the sample library and listens to the live trumpet performance in real time. Their behaviors fluctuate between responsiveness and indifference, generating shifting environments that range from highly chaotic to unexpectedly calm.

As a result, the improvising performer becomes entangled with a machine ensemble that both reflects and subverts the human gestures, creating a continuously changing dialogue between human and technological agents.
