Violearn teaches you to read violin sheet music, then listens while you play it. LEARN THE NOTES, IN ORDER A guided path from open strings to the full fingerboard. A note appears on the treble staff; you find it on the violin. Naturals, sharps and flats, one string at a time, so nothing arrives before you are ready for it. PRACTICE THAT TARGETS WHAT YOU MISS Every answer is remembered. The daily review quietly serves you more of the notes you get wrong and fewer of the ones you have already mastered, so ten minutes goes exactly where it is needed. A WHOLE PRACTICE SESSION, GUIDED Tune up, warm up, scales, then real music — in order, with the clock running. Quick Practice starts the session you did last time in one tap. Nine traditional pieces are included, from Hot Cross Buns to Pachelbel's Canon. PLAY, AND BE HEARD Violearn listens to your violin through the microphone and follows you note by note as the music scrolls past. Set how strict it should be: forgiving while you are finding the positions, strict when you are working on intonation. A TUNER THAT MEANS IT A chromatic tuner accurate to the cent, with a tap-to-hear reference for each string. Calibrate to your own instrument so every note is judged against your violin rather than a textbook. WATCH YOURSELF IMPROVE Accuracy for every note on the staff, daily practice streaks, and a "needs work" list that shrinks as you learn. BUILT FOR PRACTISING No account. No setup. Works on iPhone and iPad, in portrait or landscape — prop the iPad on a music stand and read from it. YOUR PRACTICE STAYS ON YOUR DEVICE Recordings are never stored or sent anywhere. The microphone is used only while you are actually playing. Terms of Use: https://sfanale.github.io/violearn-site/terms.html Privacy Policy: https://sfanale.github.io/violearn-site/
