Tidal is used by a diverse and vibrant community of musicians for composition, improvisation and exploration of algorithmic music. Check out the Tidal Blog or submit your own blog post. Learn about the Tidal community.

Tidal Cycles allows you to make patterns with code. It includes language for describing flexible (e.g. polyphonic, polyrhythmic, generative) sequences of sounds, notes, parameters, and all kind of information.
