  We investigated how the action–sound relationships found in electric guitar performance can be used in the design of new instruments. Thirty-one trained guitarists performed a set of basic sound-producing actions (impulsive, sustained, and iterative) and free improvisations on an electric guitar. We performed a statistical analysis of the muscle activation data (EMG) and audio recordings from the experiment. Then we trained a long short-term memory network with nine different configurations to map EMG signal to sound. We found that the preliminary models were able to predict audio energy features of free improvisations on the guitar, based on the dataset of raw EMG from the basic sound-producing actions. The results provide evidence of similarities between body motion and sound in music performance, compatible with embodied music cognition theories. They also show the potential of using machine learning on recorded performance data in the design of new musical instruments.

  QuaverSeries is a live coding language that explores the balance between minimalism and readability in live coding language syntax design. It adopts a parenthesis-free syntax and forms a left-to-right typing flow. It was first implemented with Ohm.js and Tone.js, but in this new branch of QuaverSeries, it is reimplemented with Sema Live Coding Language Ecosystem and focuses on signal modulation. In this performance, the performer will be improvising on sound synthesis and seek to arrive at a self-playing state.
