Every swara you bow is really a tiny, super-fast wiggle. Let's discover the secret speed inside your violin string — and meet every swara in the family!
Some things move back and forth really fast. Some move slowly.
A bee's wings flap super fast — that's why you hear a high bzzzz. A big drum skin moves slowly — that's why you hear a low boom.
The number of wiggles in one second has a science name: frequency. We measure it in Hertz (Hz). So 4 Hz means "4 wiggles every second."

💡 Faster wiggle = higher sound. Slower wiggle = lower sound. Slide it and hold the button to hear the violin climb!
👀A real violin string wiggles hundreds of times each second — too fast for our eyes to see! So we slowed the picture down, but the numbers are real.

Low Note, High Note
Both of these are your violin — one is a slow, big wiggle, the other a fast, tiny wiggle. Tap each one!

Slow Wiggle
A low violin note — deep, like an elephant's call.
🐦
Fast Wiggle
A high violin note — bright, like a little bird.
🎻Fun fact: the lowest open string on a violin is the G string (about 196 Hz). The thinnest string sings much higher!

Your Violin String is a Wiggler
When you bow your string, it shivers back and forth — that shiver pushes the air, and the air carries the sound to everyone's ears. 🎻➡️🌬️➡️👂
🎯 When your finger presses the string, only the part between your finger and the bridge wiggles. A shorter wiggling part wiggles faster — so the swara goes higher!
🤚This is exactly what Swara Sthānam means — the right spot on the string for each swara. Finding the spot = finding the right speed!

Sruthi — Your Home Note
Before you play a single song, you pick one note to be your home base. That home note is your Sruthi. In English we call it the tonic or base pitch.
A drone keeps humming your Sruthi the whole time, so your ears never get lost. 🎻 Your Sa is your Sruthi — and every other swara is a faster wiggle built on top of it.

🌟 Move your Sruthi and watch every swara move together — but the pattern stays the same! That's why one song sounds right whether a tall appa or a small child plays it.

The Swara Staircase
Here is the big secret: each swara is just the string wiggling at its own speed, built from your Sruthi. This is the friendly scale Shankarābharaṇam — going up is Ārohaṇam, coming down is Avarohaṇam.
Tap any step to hear it. Watch the Hz climb as you go up! 🎶

The Two Sa Twins (the Octave)
Did you notice there are two Sa's? A lower one and a higher one. They sound like the same swara — like a parent and child singing together. 👩👧
✨ The higher Sa wiggles exactly twice as fast as the lower Sa. Double the speed makes the "same swara, but higher."

🐙 This jump from one Sa to the next is called an octave — from the old word for eight (like an octopus has 8 legs!) — because Sa to the next Sa is the 8th step. In Carnatic music each octave is a Sthāyi.

The Whole Swara Family
So far we used the simple 7. But each swara has different shades — its own special seats on the string, called swarasthānams. For example, Nishadam (Ni) comes in three: Shuddha, Kaishiki, and Kākali!
🪷 Sa and Pa never move — they are the two fixed swaras (achala swaras). The other five — Ri, Ga, Ma, Da, Ni — can shift their seat, so they have variations. Altogether that makes 16 swarasthānams. Tap any one to hear it on the violin!
The 12 Seats (Chromatic Ladder)
All 16 names actually sit in just 12 spots between Sa and the upper Sa — because some swaras are roommates sharing the same seat (those are the green steps). Tap to hear each spot.

🎼 These 12 seats are the building blocks of every raga — and choosing different ones is how we build all 72 Melakarta ragas! That's a whole world to explore in your 72 Melakarta booklet.

Play Your Violin — Which Swara Is It?
Now turn the science into a game! Switch on the listener, bow a swara on your violin, and the page will hear the wiggles and tell you which swara you played — even which variation — and whether you are in tune. 🎯

Everything that makes sound is wiggling back and forth.
