Sargam Tuner
Free Online Harmonium Tuner
Choose your Sa, then sing or play one note into your microphone. See its Sargam name, Western note, and cents above or below pitch. No app or signup; microphone audio is processed on your device.
Tap Start to begin listening.
Default Sa = C. Change Sa above to match your voice or drone; this changes the Sargam labels, not the detected Western pitch. Reference tuning: A4 = 440 Hz. Keep this tuner tab visible while listening; switching away stops the microphone.
What is a Sargam tuner?
A Sargam tuner listens to a note and tells you both its Western pitch (like C, D, or E) and the matching Sargam syllable (Sa, Re, Ga…). This free harmonium tuner runs in your browser using your microphone, so you can check vocal intonation or harmonium reeds without installing an app. It defaults to Sa = C. Use the Sa selector on this page if you sing in another scale; the harmonium’s Transpose control is separate.
How to tune your harmonium or voice
Tap Start listening and play one harmonium reed, or sing a steady note. Watch the cents meter: a needle to the left means the note is flat, to the right means sharp, and centred means in tune. For vocal practice, hold Sa against the online shruti box in another tab drone and use the tuner to confirm you are landing on the right pitch. To learn how each syllable maps to a key, see the harmonium notes and Sargam guide.
A repeatable three-note tuning check
- Hold Sa for two seconds and read the stable middle of the note.
- Move to Pa, wait for the display to settle, and notice whether the note consistently leans sharp or flat.
- Return to Sa without looking at the meter, then check the display. This tests the ear as well as the instrument.
Repeat the sequence three times at the same volume. A consistent small difference is more meaningful than one perfect reading followed by two unstable ones.
Why the tuner needle keeps moving
A voice changes pitch slightly during the attack, vibrato, breath, and release. A harmonium reed can also produce overtones that make the first reading jump. Use one steady vowel, move closer to the microphone in a quiet room, and judge the centre of the held note. Do not chase every movement by tightening the throat or changing bellows pressure.
Frequently asked questions
What note is Sa on a harmonium?
Sa is your chosen reference note. This tuner defaults to C; choose any of the twelve notes in the Sa selector to match your voice or drone. Sargam labels follow that choice while Western note names stay unchanged.
How accurate is this online harmonium tuner?
The tuner estimates the pitch of one steady note and shows its deviation in cents from A4 = 440 Hz equal temperament. Microphone quality, background noise, and overtones can affect the reading. Use it as a practice aid; it does not measure chords or certify instrument calibration.
Can I use the Sargam tuner for singing practice?
Yes. Sing a sustained vowel into the microphone and the tuner shows the Sargam syllable plus how many cents you are off. Combine it with the shruti box drone and a phrase from the harmonium song notes to train your ear and your pitch together.
