Detects every note across the full musical range — C, C#, D, D# and all 12 notes — with a cents-accurate needle and frequency readout. No fixed tuning, no setup, just play.
Play one note at a time and watch the display. Any instrument, any tuning, any pitch.
The tuner begins listening immediately. You do not need to select a tuning — the chromatic engine detects whatever note you play and finds the nearest pitch automatically.
Sustain the note clearly while the display settles. Bowed, plucked and blown notes all work. The detector needs the fundamental to come through, so avoid dampening or muting the sound immediately.
The large display shows the nearest note (C, C#, D and so on). The cents reading shows how far off you are. Zero cents is perfectly in tune; negative means flat, positive means sharp.
Adjust your pitch — tighten or loosen the peg, move the tuning slide, or adjust your embouchure — until the needle sits in the middle and turns green. That note is in tune.
Standard concert pitch at A=440 Hz. Each note is a semitone apart — a factor of 2^(1/12) from the last.
| Note | Freq (A=440) | Note | Freq (A=440) |
|---|---|---|---|
| C4 | 261.63 Hz | C#4 / D♭4 | 277.18 Hz |
| D4 | 293.66 Hz | D#4 / E♭4 | 311.13 Hz |
| E4 | 329.63 Hz | F4 | 349.23 Hz |
| F#4 / G♭4 | 369.99 Hz | G4 | 392.00 Hz |
| G#4 / A♭4 | 415.30 Hz | A4 | 440.00 Hz |

A chromatic tuner is the swiss army knife. Here are the specialised tools for specific instruments.
A chromatic tuner detects all 12 notes of the Western scale — C, C#, D, D#, E, F, F#, G, G#, A, A# and B — rather than only fixed string pitches. It works for any instrument in any tuning.
Yes. Guitar, bass, violin, ukulele, mandolin, banjo, wind instruments, brass — any instrument that produces a sustained pitch. The tuner detects the nearest note and shows the cents deviation.
Cents measure how far off you are from the nearest semitone. Zero is perfectly in tune. +50 cents means you are halfway between this note and the note above; -50 means halfway below. Within ±5 cents is accurate for any recording or performance.
The tuner detects pitches from around 25 Hz to 4500 Hz, covering bass guitar low-B through well above a violin's highest open string.
