This study presents a sonification tool – SonifyFOLK – designed for intuitive access by musicians and dancers in their sonic explorations of movements in dance performances. It is implemented as a web-based application to facilitate accessible audio parameter mapping of movement data for non-experts, and applied and evaluated with Swedish folk musicians and dancers in their exploration of sonifying dance. SonifyFOLK is based on the WebAudioXML Sonification Toolkit and is designed within a group of artists and engineers using artistic goals as drivers for the sound design. The design addresses challenges of providing an accessible interface for mapping movement data to audio parameters, managing multi-dimensional data and creating audio mapping templates for a contextually grounded sound design. The evaluation documents a diversity of sonification outcomes, reflections by participants that imply curiosity for further work on sonification, as well as the importance of the immediacy of the both visual and acoustic feedback of parameter choices.
