Sa Finder

A free one-screen tool for finding and saving your Sa — the home note the rest of your practice is built on — for singers at any level. No sign-up, runs in the browser. Pick a shruthi, hear a tanpura drone, and save the one your voice settles in. Use this Sa across the other Labs tools.

How to use Sa Finder

1. Step through the shruthi options and hear each tanpura drone.
2. Hum or sing along to find the one that feels effortless.
3. Save your Sa — the other Labs music tools will read it from local storage.

Frequently asked questions

What is "your Sa"?

Sa is your home note — the tonic your voice (or instrument) settles into without strain. Every other note in Carnatic music is relative to this one.

How do I pick the right Sa?

Cycle through the drones and hum along. The right Sa is the one you can sustain for a long breath without pushing the voice up or down.

Where is my Sa saved?

Locally in your browser via localStorage. The other Labs music tools read this value so you don’t have to set it again.
