#1 Intelligent Music Practice Tool — trusted by ABRSM, Buffet Crampon and Pleyel, and millions of practicing musicians and teachers worldwide.
Play, teach and progress, in lessons or at home. 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.
TOOLS TO MAKE EVERY SESSION COUNT
• Practice offline with downloaded pieces, even without an internet connection.
• Repeat difficult passages with loops and a metronome.
• Add annotations, highlights and musical markings.
• Tune your instrument with the built-in tuner.
• Stay in sync with automatic Bluetooth audio delay compensation.
• Read comfortably with zoom, scrolling and page-turn options.
• Print sheet music where available.
• Practice piano one hand at a time on supported pieces, while Metronaut plays the other.

Downloaded it for a bit and it looks like it is a great app to practice! If you fall into the main category that the app falls to. Most pieces are classical, which is fine, unless you fall into a nonclassical instrument. Plus some people don’t want to really play classical. For example I downloaded this app and as a Sax player in my school’s jazz band, I want to play some jazz. Unfortunately I couldn’t find one single piece like that.This app has a whole lot of potential that I hope they expand on eventually. Imagine if they could have lessons for your instrument with it. They could have little classes where they could teach improv for example.Great app, Just aint for me.
I won’t pay to play!

WARNING: If this review is over 2 months old, DO NOT continue reading. The things in this review might have already been fixed in an update. Therefore, the review is then completely useless. Please click out right now and find a review that is less than 2 months old, and read that. Thanks! So I downloaded Metronaut for learning purposes. I take private lessons for the flute, and wanted to up my game for exams. I hopped into the app and tapped on one of the community posts. I listened to Ave Maria for a bit, and thought that it was really cool that you could share your learning on here! And then I clicked out of it and it kicked me out of the app, which was super annoying, and then I thought, let’s do some practicing! So I tapped on Japanese flute method lesson 1, and it loaded some pieces for me to play. I chose the first one, Lightly Row, and then noticed that I couldn’t play the full song without paying for the premium. I thought, whatever, it’s probably just for this one song. But no. You have to pay for premium to play the full version for EVERY SONG. YOU GET 2 BARS OF MUSIC, AND ONE THAT’S HALF FADED! I’M VERY DISAPPOINTED!!! Please fix this. I also play piano, so I find it annoying that I cannot select 2 instruments. Please make it only premium for select songs, like very popular pop or rock songs, not ALL OF THEM! What if there’s a 3 year old violinist who wants to play full songs? This is truly unacceptable. Please fix all of this!
A bit crusty ig
ALL are precious in His sight.
The app design is very smooth 👏 and I was surprised that there are actual known songs, though I’d like to see more. This app is supposed to help me stay on beat right? I don’t think it did, it just messed me up. A lot of the songs I tried I know by heart and the audios matched, but when I tried to sing with the tempo and following the notes, it didn’t come out right. I’m not a professional (you can probably tell by my lack of musical terms) but this was much harder than when I sing with a real accompanist. Also, I don’t understand what notes I’m even supposed to be singing with this? It has all the notes but the person singing stops at certain points. Then when I recorded myself and listened back, the accompaniment was way louder than my voice. And adjusting the solo - accompaniment audio (to the solo side) just made the accompaniment sound very distorted and even louder. I only had the free version but I think the free version experience should be good enough to make me want to buy the subscription. The sessions cut out at very awkward spots. Mid word. or sometimes the singing parts start near the end of the session then I sing for 1 second lol. Anyway, it has potential but yeah there’s a lot of things that just made me say “okay im done”. And an IDEA maybe you could allow the user to scan their own sheet music and the it just plays piano or something in the background so I can practice the pieces I actually need to be practicing. Well, thanks for reading my super confusing review. <3
Developer Response
Thanks for your superbe thorough and detailed review! 🙏 Did you try the Smart feature in the Tempo? It will make the accompaniment adapt to you as you sing! 😇 Also: regarding the recording distortion: use either a headphone or even external speakers (any would work!). The play along track, when loud, enters the mic and distorts everything.Given your efforts, we would love to offer you a 30 day Free Premium access to dig things further! Just contact us from the App mentioning this message and we’ll vibe glad to make you going.
Almost good but not quite

I had high hopes for this app, and wanted to try it out to see if it would be helpful for my students, and also see if it would be helpful in my own practice. For me personally, I knew right away that it wouldn’t be all that helpful since it only has a few solo pieces for my instrument (horn). It would be more helpful if it had orchestral excerpts and etudes, and some less standard solo works as well. For a little while I thought it might still be good for my students but it turned out to be just not that great after trying it out with a few pieces. My main complaints are: when the metronome feature is turned on, it is slightly off from the accompaniment that is playing, as is the highlighted bar. Occasionally the accompaniment just completely froze on one note, like it wasn’t picking up my playing correctly. I also noticed it would pause when it picked up the sound from me emptying my horn in the rests. And anytime there was a tempo change it simply did not work well at all. If those were improved, it might be helpful for younger players, and if there was more repertoire it might be better for me.
