Contrapunctus is a free web platform for music theory, composition, and counterpoint study. Its real-time editor shows Roman-numeral and chord analysis while users write, and identifies part-writing errors and non-chord tones. Compositions can use multiple voices, major, minor, or modal contexts, and sampled-instrument playback. The platform includes an interactive edition of Fux’s Gradus ad Parnassum, with species-counterpoint lessons, an AI tutor, and English and Latin text. Community members can create and solve exercises, share solutions, vote, and earn points toward a 15-rank ladder. Educators can create classes, assign lessons, review submissions, and track scores and class averages in a gradebook. Accounts use email or Google, with projects and activity synchronized across devices. Plain and compressed MusicXML can be imported, but MusicXML or MIDI export is not yet shipped. Some imported details may be simplified or dropped, and tutor free-form questions are limited to 25 per account per rolling hour.
