Scores by Jeff Kaiser

Most of the following scores use a hybrid notation that combines traditional and graphic elements. Several of the scores are for large ensemble: 132350 and 13 Themes for a Triskaidekaphobic are modular and the form is improvised by the conductor. Other scores are more through-composed, but all contain elements of improvisation: one is for large ensemble and choir (The Alchemical Mass), one for choir and electronics (The Answer to Job), one for solo marimba and electronics (9503 , plus a variation for voice and electronics, 9503 Maryknoll), one for quintet (Glasses—four themes based on the shapes of drinking glasses), and Wise Toupée for clarinet and electronics. All of the works including electronics use custom digital signal processing and ambisonic software I author in Max.

Included are my Improvising Machine series (for improvising machine and indeterminate instruments) that have been written for my friends, including clarinetist Elisabeth Stimpert, pianist Albert Kim, trumpet player Alan Wenger, and horn player Gabriel Trottier. These works all use a machine improvisation algorithm that listens to —and sometimes ignores—the human performer. One performance is currently available on video (Gabriel Trottier) here: https://youtu.be/XZCxWvBp49k

Most of my software is available free and linked in the menu at the top of the page. This machine improvisation software (KaiGen-I) has been developed as both a Max patch and Max for Live plugin for use in Ableton Live) will be available soon for free for your own use, or with the score and Ableton sessions for performance.

All scores available in high resolution PDFs for performance.
