A chromatic tuner that listens through your mic and shows the nearest note with cents precision. Standard GDAE tuning with reference tones for each string. Works for fiddle too.
Bow strokes often give a cleaner signal than plucking. Start with the A string and work outward.
Click the button below and allow microphone access. The tuner begins detecting immediately. Bow or pluck one string at a time.
Draw a steady bow stroke on one string, away from the bridge but not too far toward the scroll. A smooth, even bow speed gives the cleanest fundamental for the detector to read.
If the display shows the right letter, adjust the peg or fine-tuner until the needle centres on green. Within two or three cents is more than close enough for any ensemble or recording.
G is the hardest to read because its overtones are strong relative to the fundamental. Bow slightly faster and stay near the nut. If the octave jumps, bow with less weight.
Standard violin tuning is GDAE in perfect fifths. The A string at 440 Hz is the standard concert pitch reference.
| String | Note | Frequency |
|---|---|---|
| G (4th) | G3 | 196.00 Hz |
| D (3rd) | D4 | 293.66 Hz |
| A (2nd) | A4 | 440.00 Hz |
| E (1st) | E5 | 659.25 Hz |

Tuning is step one. Here is what players and producers reach for next.
Yes, and bowing usually gives a cleaner, more stable signal than pizzicato. Draw a slow, even bow stroke on one string while watching the display settle.
Yes. Viola strings are CGDA (C3, G3, D4, A4). Use the Chromatic Tuner and tune each string to its target note, or tune your C string by ear against the G reference tone here.
Fiddle and violin are the same instrument with the same standard GDAE tuning. This page works identically for both.
No. The tuner runs entirely in your browser. Mic audio is processed locally and never uploaded or stored.
