Hear violin sheet music, then check your tuning
Musaica is a free online sheet music reader. Upload a PDF or photo of a violin part, choose the Violin voice, and it plays the recognised score on a sampled violin with a cursor following each note. Because the violin has no frets, the most useful part for many players is what comes next: playing the passage yourself while the microphone intonation check shows whether each note is sharp, flat or in tune.
How violin notation works
Violin music is written in the treble clef at concert pitch: the violin is not a transposing instrument, so the note on the page is the note you hear. The open strings are G3, D4, A4 and E5. The lowest note is the open G; the top of the range is around E7 for advanced players, so high passages use ledger lines or an 8va sign.
| Marking | Meaning | In playback |
|---|---|---|
| ⊓ and V above notes | Down-bow and up-bow | Not reproduced |
| Curved slur over several notes | Play them in one bow | Notes sound for their written values |
| 0–4 above a note | Open string or finger number | Not played |
| Two notes on one stem | Double stop | Both notes sound together |
| pizz. / arco | Pluck / return to the bow | Not reproduced; the bowed sound continues |
| Diamond-shaped notehead | Harmonic | May sound at the written rather than the sounding pitch |
The violin voice is a set of recorded bowed notes. It gives you the pitch, length and colour of each note, but not vibrato, bow strokes such as spiccato, or slides between positions.
Using the intonation check
Turn on the microphone, start playback and play along. For each note the check compares the pitch you play with the written note and shows the result on a tuner gauge and a pitch trace. At the end of a session you get a report showing which notes you tend to play sharp or flat, so you can see patterns rather than isolated slips.
- Practise slowly. Set the passage to 50–70% speed. The check needs a stable note to judge, and slow practice is where intonation is fixed anyway.
- Read the report as a map. If every C natural on the A string comes out sharp, your second finger is drifting toward C sharp; if high-position notes run flat, your hand frame may be closing up.
- Loop the worst bar. Select it, loop it and play until the gauge settles in the centre, then widen the loop.
- Use it as a tuner. While playback is stopped the check behaves like a tuner, which is handy for tuning open strings before you start.
The target is equal temperament, the tuning of a piano. Many string players adjust some notes slightly, for example raising leading notes or matching open strings, so a few cents of difference is normal. Aim for consistency first. The check ignores octaves, so a note played in the wrong octave is still judged on its name.
Other ways playback helps
- Hear an unfamiliar part before a lesson or rehearsal, especially orchestral second-violin parts that make little sense alone.
- Lock in rhythm with the rhythm counter ("1 e & a", bars or circle) and the metronome.
- Work up tempo with the 10%–200% speed control: learn a passage slowly, then raise the speed a few percent at a time.
What to expect from recognition
A single violin part on a clean page usually recognises well. Things to check against the page: grace notes, which often fail; small cue notes, which may be played as if they were your part; multi-bar rests; and very high passages with many ledger lines. If you upload a violin-and-piano score, the whole score plays in the instrument you pick, so for practising your own line the solo part alone is clearer. Our scanning guide covers how to get a sharp image from a phone.
Free, honestly. Uploading and playing scores is free and ad-supported. Without an account you get an instant preview; a free account (we email you a sign-in link, no password) unlocks the full score and saves it to your library. The paid plan, Musaica Basic ($5.99/month), removes ads and adds Smart Playback, Band Mode, MusicXML export and HD audio renders.
How to practise a violin part with intonation feedback
- Upload your part. Drop a PDF or photo of the violin part, ideally the solo part rather than the full score.
- Listen with the Violin voice. Choose Violin and play the passage through while following the cursor.
- Turn on the microphone and play along. Slow the passage down, loop it and watch the tuner gauge and pitch trace as you play.
- Read the report. At the end of the session, see which notes ran sharp or flat and loop those bars again.
Frequently asked questions
Can Musaica tell me if I am playing the violin in tune?
Yes. The microphone intonation check compares each note you play with the written note, shows it on a tuner gauge and pitch trace, and gives you a report of which notes tend to be sharp or flat.
Does the violin playback include vibrato or bowings?
No. It uses recorded violin notes, so you hear the pitches, rhythm and colour of the instrument, but not vibrato, bow strokes or slides.
Is violin music written at the pitch it sounds?
Yes. The violin is a non-transposing instrument written in treble clef, so the written note is the note you hear.
Can I slow down a violin part to practise?
Yes. Play any passage from 10% to 200% speed and loop any range of bars.
Why does the check say a note is a few cents off when it sounds fine?
The target is equal temperament. String players often adjust notes slightly by ear, so small differences are normal. Look for consistent patterns rather than single readings.
