Welcome to Sidosi, the de facto modern home of Solresol, the universal musical language! The goal of Sidosi is to be a comprehensive, up-to-date, and most importantly permanent resource for learning Solresol. Sidosi currently hosts an active forum community, a community-edited Solresol wiki/knowledge base, a large list and archive of Solresol resources, and a basic Solresol translator.
