FaSoLaMix is a multimedia application designed to teach Sacred Harp singing to both new and experienced singers. The app aims to provide a virtual experience of sitting next to strong singers, allowing users to control the mix of the four vocal parts in high-quality recordings of Sacred Harp songs. Users can isolate specific parts for practice, making it ideal for newcomers learning a particular vocal line or experienced singers enhancing their skills. The app comes with 24 songs of varying difficulty levels, regularly featured at all-day singings and conventions, with additional song packs available for purchase periodically.

FaSoLaMix offers a unique opportunity for singers to improve their skills and enjoy the tradition of Sacred Harp singing, with all proceeds supporting the Sacred Harp Musical Heritage Association.
