This paper presents WELLE, a web-based music environment for blind people, and describes its development, design, notation syntax and first experiences. WELLE is intended to serve as a collaborative, performative and educational tool to quickly create and record musical ideas. It is pattern-oriented, based on textual notation and focuses on accessibility, playful interaction and ease of use.
WELLE was developed as part of the research project Tangible Signals and will also serve as a platform for the integration of upcoming new interfaces.
