Composer George Lewis designed Voyager to make music even when its human partner stopped. It could respond, oppose or carry on independently: the computer’s decisions became musical material the performer had to consider.[1]
In his 2000 account, the orchestra had 64 virtual players producing digital note commands, regrouped into ensembles every five to seven seconds. Each group could take cues from one human, two or neither. There was no leader’s pedal or veto button; communication happened through sound.[1]
For Lewis, that plurality embodied African-American improvisational practice. Software could carry a musical culture’s assumptions about how voices coexist.[1]
Teaching it to hear a gesture
During Lewis’s 2021–22 residency at the Royal Northern College of Music, his collaborators trained a recogniser on musical gestures chosen in advance. It added cues Voyager’s existing listeners found hard to identify.[2]
The result became Forager, a work for five players and an interactive pianist, premiered in Manchester on 25 November 2022. In Lewis’s explanation, the new component searches a live performance for recognisable gestures to which the larger piano system can respond.[2]
Better listening broadened the material available to an independent musical partner.[2]
