'Calder's Violin' is a composition for violin and automatic piano. The music is algorithmically generated, including the violin part which is notated live as the piece progresses. The general textures and references of the music are intended to be predictable, but detail is new each time: an attempt to emulate in the medium of electronically generated music the 'mystifyingly exquisite variation' of performance on traditional, acoustic instruments. Some of the material for Calder's Violin has been previously developed for the on-going dance and music project 'Triggered'.

The piece is still being developed with regard to other instruments and enhancements in both SuperCollider and INScore enhancements. The 2022 Marseilles version features a more developed 'translation' algorithm to aid performance on different instruments.

The piece is primarily composed in the music programming environment, SuperCollider.

This piece uses the software INScore and Guido significantly, both currently being developed by the Grame Computer Music Research Lab.
