Abstract:

Algorithmic Power Ballads is a performance for Saxophone and autonomous improvisor, with an optional third performer who can use the web interface to hand-write note sequences, and adjust synthesis parameters. The performance system explores shifting power dynamics between acoustic, algorithmic and autonomous performers through modifying the amount of control and agency they have over the sound over the duration of the performance. A higher-level algorithm how strongly the machine listening algorithms, which analyse the saxophone input, influence the rhythmic and melodic patterns generated by the system. The autonomous improvisor is trained on power ballad melodies prior to the performance and in lieu of influence from the saxophonist and live coder strays towards melodic phrases from this musical style. The piece is written in javascript and WebAudio API and uses MMLL a browser-based machine listening library.
