Metronaut combines interactive sheet music, professional accompaniments and AI Feedback that listens to your playing. Rooted in research at IRCAM in Paris, Metronaut brings technology used in performances with leading orchestras worldwide to your everyday practice. YOUR INSTRUMENT, YOUR SCORE Explore over 20,000 high-quality sheet music titles, with new repertoire added regularly. Play pieces written for other instruments, too. Metronaut automatically adapts the sheet music to your instrument’s clef and range. Adjust the key, octave, clef or tuning reference; the accompaniment adapts while preserving its sound quality. HEAR WHAT TO IMPROVE WITH AI Feedback See how accurately you play, directly on your sheet music. Get instant visual feedback on pitch and rhythm, a performance rating from 0 to 100, and XP to track your progress. AI Feedback works with every piece and instrument, including acoustic piano and guitar. Use your microphone or connect a digital MIDI instrument. Get feedback even while playing along with accompaniment — no headphones needed. FOUR MODES, YOUR WAY TO PRACTICE • Listen — Get to know the piece and hear your part before you play. • Sight-read — Take your time. The cursor advances when you play the right note or chord, without accompaniment. • Practice — Build accuracy at a steady tempo, with accompaniment when available. Start slowly and increase the speed as you improve. • Interpret (AI Tempo) — Accompaniment that follows your lead, adapting to your tempo in real time for expressive phrasing. Use AI Feedback alongside Sight-read, Practice or Interpret (AI Tempo). RECORD AND REPLAY WITH YOUR SHEET MUSIC Record audio or video and replay your performance in sync with your sheet music. Teachers can assign pieces and playlists, then exchange recordings privately with students between lessons. Share your performances with the Metronaut community, too.
