A performance by Doug Perkins of Spatial Network for Percussion in Spaulding Auditorium at Dartmouth College. The score for this piece is generated by a Processing application and is never the same twice.
Program notes from the concert:
Spatial Network for Percussion
The performer of Spatial Network for Percussion is accompanied on stage by a computer. The computer uses a topological map to generate paths across the performer's instrument. These paths are displayed on the screen as an ever-changing musical score. Structure emerges from a hierarchical tree of constraints applied to both the path generation algorithm and performative parameters such as volume, striking implement, etc. No two performances are the same.
Confining performers to a fixed set of movements eliminates the possibility of choice and encourages a radically limited relationship with their musical instruments and audience. Instead, Spatial Network for Percussion encourages the performer to develop a flexible set of relational strategies that become the subject of the piece.
