Tuner
A chromatic tuner for any instrument or voice, with string presets and a Sa mode for Indian music.
Tuner reading
Your browser will ask for the microphone. Sound stays in this tab.
Settings
Sing or play your Sa and hold it for two seconds. The tuner picks the nearest note.
In Sa mode the swaras are placed in equal temperament from your Sa, so cents are measured from the equal-tempered position. Swara names are Hindustani (komal and tivra). Turn on Indian terms in the footer to see them in Devanagari too.
About the microphone
- You press Start. Only then does your browser ask to use the microphone. Nothing is asked when the page opens.
- The sound stays here. It is analysed inside this browser tab to find the pitch. It is never recorded, saved or sent anywhere.
- Stop switches it off. Press Stop tuner, or close the page, and the microphone is released.
If the microphone was blocked
Open your browser's settings for this site (often behind the icon to the left of the address) and set Microphone to Allow, then press Start again. On a phone, also check that the browser itself may use the microphone in the phone's settings.
The tuner only works on secure pages (https:// or localhost).
How to use it
- Press Start tuner and allow the microphone.
- Play or sing one steady note, close to the device.
- Tune until the needle is in the centre and the reading says In tune (within 5 cents).
Note names use letters with the octave number (middle C is C4). Black keys show both names, for example C♯/D♭. Pick an instrument to see which string you are nearest to and how far off it is. Need a note to match? Open the drone and pitch pipe.
