Single Finger Mode is a piece for a pianist and a computer playing together on one piano. The piece is composed algorithmically, which allows the computer to rate the accuracy of the live-performance compared to the score. With each note it computes a highscore and uses it to generate an accompaniment to the notes played by the performer. The more accurate the computer considers the performance, the more it will be tamed and adjust to the music played. The less accurate the computer considers the performance, the more will it come to live on its own: It likes tonal chords and consonances very much and is always in for a little fun.

Recorded live on 06.07.2021 at Pina Bausch Theater, Essen. Performed by Ying Yu (piano).
