Violin Tuner & Intonation

Tune your violin and improve your intonation with live pitch feedback, fingerboard exploration, ear training, and a built-in metronome.

See and refine your intonation
Live pitch feedback shows whether each note is sharp, flat, or centered. Adjust the A4 reference to match your instrument or ensemble.

Practice scales with a clear target
Guided practice in Pro follows major and minor scales, arpeggios, and combined exercises. Choose your key, octave range, direction, and rounds. Play at your own pace or follow a set tempo with an optional count-in.

Hear notes and explore the fingerboard
Connect written notes with fingerboard positions, explore double stops, and train your ear by finding the notes you hear. Preview notes with sampled bowed or pizzicato violin sounds, or a synthesized reference tone.

Review and repeat
Capture pitch samples, review intonation note by note, and repeat an exercise with the same setup. Takes store pitch data only; microphone audio is not saved.

Keep a steady pulse
Use the built-in metronome with accents, subdivisions, Tap Tempo, Tempo Trainer, and Quiet Count.
