We present the first combined use of the electromyogram (EMG) andmechanomyogram (MMG), two biosignals that result from muscular activity, forinteractive music applications. We exploit differences between these twosignals, as reported in the biomedical literature, to create bi-modalsonification and sound synthesis mappings that allow performers to distinguishthe two components in a single complex arm gesture. We study non-expertplayers’ ability to articulate the different modalities. Results show thatpurposely designed gestures and mapping techniques enable novices to rapidlylearn to independently control the two biosignals.
