Uncertain circle is an interactive live performance piece by Keith Armstrong and Andrew Brown. The performance involves a live performer interacting with digital video and synthesizer sound.
Visually, Uncertain Circle mixes digitised video with live silhouettes from the Mandala Virtual reality system. Interaction between the live performer, his digital surrogate and video images of the performer and surrogate integrate into a collage of virtual relationships.
Uncertain circle deals with these relationships as symbolic of real and potential relationships between humans and the virtual worlds and virtual inhabitants they create. At another level it is about the technological and biological selves within us and their interrelationship and mutual control.
The score contains various music sequences linked to video segments, as the video segments are triggered the appropriate music is also played. The order of music and video segments in sections during creation was at times random while mostly preset.
This flexibility presents an interesting challenge both compositionally and technically. Many of the musical segments are written so that they can be played in any order and even overlap without serious harmonic or rhythmic clashes. The technical side of performing randomly selected and concurrently sounding musical sequences was performed by a computer music program called MAX. The composer programmed MAX (a computer language) to achieve the desired outcome and specific extensions to Macromind Director were written in C to link the music and video triggers from the Mandala live performance. In pieces like Uncertain Circle which incorporate live and computer-based performance, writing programs to achieve interaction becomes an inherent part of the compositional process.
