Play along the score
Count-in, metronome, then the score follows you. Each note takes its colour as you play it; at the end, a score for pitch, rhythm and duration, and the heard deviation under every note to work on.
Play in tune,
in time. Solutfa listens.
Solutfa listens to your instrument through the microphone — designed for instruments played one note at a time — and colours every note of the score as you play it: green, orange or red. You see at once what is in tune and what is not.

What Solutfa does
See your progress
Your practice days, your scores going up, and above all what to work on: the tricky passages coloured on the score, the notes you play sharp or flat, the tempo you can hold. By day, week or month.
Tuner and metronome
A tuner to the cent, with an adjustable reference (A 440, 442…), and a metronome with count-in, subdivisions and a loop on a section.
Share with your teacher
One link is enough: the score, or your take with its recording and colours, shows up in your teacher's app — kept apart from their own takes.
Your scores
A library of well-known pieces in treble, alto and bass clef, drum exercises 𝄥, MusicXML and MEI import, an editor to write your own — by keyboard, microphone or MIDI — and scanning of printed sheet music.
Play with an accompaniment
Add a piano or orchestra recording: it sets the tempo, slows down for practice, and your playing is scored in time with it.
For teachers
- One piece, one link. Or a QR code to scan in the lesson: your pupils open it straight away, no account needed.
- Hear their practice. From their account, a pupil sends you their take: you hear it, and see its colours and the heard deviation under every note to work on.
- Write the exercise. With the editor or by scanning a printed page, in treble, alto or bass clef, then send it.
Your whole practice kit, in your pocket
Our commitments
- Free. Everything described here is, with no time limit.
- No account. The app starts right away. An optional, free account backs up your takes.
- Solutfa Plus, if you want more. A free account backs up 60 minutes of takes and scans 5 sheets a day; Solutfa Plus raises that to 20 hours and 50 sheets, and brings your history to all your devices: €3.99 per month or €39.99 per year, cancel at any time. You get it from My account, where you also manage your account, game consents and data.
- Your recordings serve you only. The analysis runs in the browser; without an account nothing leaves the phone except what you export or share; with an account your takes are saved for you alone, never listened to nor exploited, and a bin is always next to them.
- Designed for instruments played one note at a time. Calibrated on real viola takes; violin, cello, flute, clarinet, trumpet and horn tried out on recorded notes; voice, saxophone and double bass being tested. Piano: melodies and chords (up to 4 notes) on a single staff, from a MIDI keyboard — tried out on a virtual student, not yet on a real keyboard. Drums 𝄥: rhythm judged on the microphone, tried out on recorded hits; the drum you hit judged over MIDI, tried out on a virtual student, not yet on a real module. MIDI needs Chrome on Android, or Chrome, Edge or Firefox on a computer (not Safari, iPhone or iPad). Adjustable tolerances.
- In your language. An interface made of musicians' symbols, explained in English, French or Spanish where it helps; note names (Do Re Mi, C D E…) are a separate setting.
- Hosted in Europe, no ads, no trackers.
