What is a chromatic tuner?
A chromatic tuner detects any note, not just the strings of one instrument. Instead of choosing a guitar or a violin first, you play a note and the tuner names it and shows whether it is flat, sharp or in tune. That makes it useful for instruments that have no fixed set of strings, and for checking any pitch.
How to use the chromatic tuner
Find a quiet spot
Hold your instrument close to your device and play one note at a time. Pause any music or video first.
Start the tuner
Start the tuner and allow microphone access when your browser asks.
Play one note
Play a single note and let it ring. The tuner shows the note it hears.
Read the result
Flat means the note is too low and sharp means it is too high. Adjust your instrument until the tuner shows the note is in tune.
Adjust slowly
Make small changes and play the note again after each one. Small steps are easier to get exactly right.
Move to the next note
Tune the next string or note the same way. Check them all once more at the end.
12-tone equal temperament (octave 4)
Standard international A4 = 440 Hz concert pitch.
Tips for tuning with a chromatic tuner
Play one note at a time
The tuner reads one pitch at a time. Mute the other strings or play a single note so it does not get confused.
Reduce background noise
Turn off music and fans, and keep other instruments quiet while you tune. Noise can make the reading jump.
Hold the note steadily
Keep the note going for a second or two. A steady, sustained note gives a more stable reading than a very short one.
Warm up first
Wind and brass instruments change pitch as they warm up. Play for a minute before you tune.
Consistent volume
A medium, confident pluck or vocal tone gives the clearest signal and the steadiest reading.
Instruments you can tune
A chromatic tuner works for any instrument that plays a steady pitch, including flute, clarinet, trumpet, trombone, saxophone, mandolin and your voice. For guitar, ukulele, violin, viola, cello, bass guitar and banjo, use the dedicated tuner, which already knows the notes of each string.

Chromatic tuner FAQ

Yes, it detects any note. It shows the pitch that is actually sounding. A B-flat trumpet or clarinet sounds a whole step lower than the written note, and saxophones are transposing instruments too.
