Contrapunctus vs Musicca

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.

Musicca is a free music-learning platform for students, educators, and musicians, available on the web and mobile devices. Exercises cover notes, rhythms, intervals, chords, scales, key signatures, instruments, and genres. Learners can also use virtual piano and guitar tools, a metronome, tuner, chord finder, and scale finder. Points, medals, stars, streaks, and weekly leaderboards add game elements to practice. An account is needed to save exercise progress; registration is available by email, Google, or Facebook. Teachers can create classes to manage students and follow their progress. Musicca says logged-in users do not see ads, while advertising helps keep the service free. Users can disable the leaderboard. For enrolled students, names, email addresses, and exercise progress are shared with their teacher. The service has no app, but its website works on mobile with an internet connection. It offers no offline access or live feedback during practice. Musicca was founded in Denmark in 2019 by Lasse Grubbe. Help articles and company contact are available for support.
