Chromatic tuner
In chromatic mode the tuner doesn't look for strings. It names any note it hears, to the cent. Use it for wind instruments, voice, harp, zither or any custom tuning.

How to tune
- Press “Start tuning” and allow the microphone. The sound stays in your browser and is never uploaded.
- Warm up a wind instrument for a few minutes first: a cold instrument plays flat.
- When singing, hold one long, steady note without vibrato so the needle settles.
- If your group doesn't tune to A = 440 Hz, change the reference (415–466 Hz).
- When the needle sits in the green middle zone (±3 cents), the string is in tune. Anything within 5 cents sounds in tune to the ear.

Frequently asked questions
What is a chromatic tuner?
A tuner that recognizes all 12 semitones, not just the strings of one instrument. It shows the nearest note and how far off you are in cents (1 semitone = 100 cents).
Does it work for transposing instruments (B♭ clarinet, E♭ sax)?
It shows the concert pitch you actually play. On a B♭ clarinet the displayed note is a whole step below the written note: your written C shows as B♭.
How accurate is it?
About ±1–2 cents on a clean, sustained note. It depends on your microphone and background noise. Anything within ±5 cents sounds in tune to the ear.
