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 assumes Sa = C by default; change the root with the Transpose control on the web harmonium if you sing in another scale.
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 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.
Frequently asked questions
What note is Sa on a harmonium?
By default this tuner treats Sa as C (middle C, MIDI 60). Sa is a movable reference, so many singers set it to C, D, F, or F# to suit their voice. Pick the key that feels comfortable, then keep every other Sargam note relative to it.
How accurate is this online harmonium tuner?
The tuner reports your pitch in cents (hundredths of a semitone) in real time. It is precise enough for vocal intonation and for checking whether a harmonium reed is drifting flat or sharp, as long as you play one clear note at a time in a quiet room.
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.
