Bringing Classical Counterpoint Rules to Live Guitar in Real Time

Contrapunk delivers real-time harmonic accompaniment based on centuries-old counterpoint rules, achieving sub-10ms latency suitable for live performance. Built in Rust and deployed as free, open-source software accessible through any browser, it makes sophisticated classical harmony principles available to all musicians. The project demonstrates how systems programming and music theory can combine to preserve and democratize fundamental principles of Western musical tradition.
