Never touched an instrument?

Start here. Three steps.

You don't need a guru or a ₹60,000 veena to start. The path: pick what fits, make one sound, follow a 5-minute lesson. That's it.

  1. 01

    Pick an instrument

    Vīṇā, vāyalin, veṇu, mṛdaṅgam, ghaṭam — five seconds of tapping to find what fits you.

    Take the 30-second quiz →
  2. 02

    Make your first sound

    No lessons, no setup. Tap one swara on a virtual veena, bow one open string, blow one flute note.

    Open the free tuner →
  3. 03

    Follow a 5-minute lesson

    Karunattu listens. It shows your pitch in cents and gives feedback on your gamaka's rate and depth.

    See how feedback works →

For absolute beginners

Which instrument fits you?

A 30-second quiz for people who've never picked one up before.

  1. 1.How do you picture yourself playing?

  2. 2.Which sound pulls you in?

  3. 3.Are you drawn to melody or rhythm?

  4. 4.What's your starting setup?

The 12-vs-22 argument

Why your DAW can't play
Mōhanam the way your guru sings it.

A 12-TET keyboard has 12 equally-spaced notes per octave. Carnatic music has seven swarasthanas spread over twenty-two śruti positions. Seven of those swaras — the Prati notes — sit between the piano keys. Toggle the view to see them appear.

22 śrutis give every Prati swara a precise position.
Mōhanam, Hindōlam, Sahānā, Behāg — most ragas need them.

Built differently

A blank tuner doesn't know
that R₃ ≡ G₂.
Karunattu does.

Every other music app treats Carnatic as a folder of MIDI presets. We treat it as a system — with grammar, source citations, and tests that catch when a raga's scale gets quietly broken.

Musicology with citations

Every raga, every signature phrase, every grading note is grounded in Sambamoorthy or Subbarama Dīkṣitar's SSP. The 37 corrections we shipped each carry the inline source comment that justified them.

±5¢ pitch precision

Server-side YIN with parabolic interp. Same algorithm as studio tuners. Cross-validated against librosa.pyin on 20 harmonic-tone fixtures; the audio QA sidecar hard-gates any regression.

Carnatic-inspired instrument timbres

Explore voice, vīṇā, violin, flute, nāgasvaram, and mṛdaṅgam timbres shaped for a Carnatic practice experience.

Server-side math, always

The pitch detector, the raga grammar, the synth engines, the mastering chain — all behind `import 'server-only'`. Your browser receives audio bytes and JSON, never algorithms.

Newbie-friendly onboarding

Five first-questions, one instrument quiz, a 5-minute first lesson. The Carnatic tradition is dense; Karunattu is the on-ramp that respects your time.

26 gamakas

The ornaments that make Carnatic Carnatic.

Catalogued from the Saṅgīta Ratnākara and Saṅgīta Pārijāta. Each gamaka is a named pitch gesture with a measured cents curve — not a Western vibrato. The Gamaka Lab has all 26; here are four to start with.

Oscillatory±50¢

Kampita

kampita

A rapid shake between two pitches. The signature ornament of Lalgudi's violin style.

Oscillatory±50¢

Āndōlan

āndōlan

A slow, wide oscillation — gentle, sustained, the vocal gamaka par excellence.

Oscillatory±50¢

Sphurita

sphurita

A very fast, small-amplitude shake on a single pitch. Subtle ornamentation.

Slide±50¢

Jhārā

jhārā

A quick, slightly meandering glide up to the target note. Common in prayōga.

Synthetic Carnatic instrument examples

These examples are generated by Karunattu's instrument models. They illustrate timbre and are not archival recordings or replicas of named artists.

How it's built

Musicology with citations.
Engineering with tests.

Every raga's scale degrees and signature phrase reads from a single source-of-truth grounded in Sambamoorthy's South Indian Music and (where the data needs it) Subbarama Dīkṣitar's Saṅgīta Sampradāya Pradarśinī. A regression test locks the signature-phrase ↔ degree-array consistency so the kind of bug that lets you accidentally teach a wrong Mōhanam can't ship.

FAQ

Common questions.

Can I cancel any time?

Yes. Cancel from your account page in one click. You keep access through the end of the current billing period.

What is on the free tier?

The 22-śruti tuner, the raga catalogue, the composers + instruments dungeons, and a phrase preview. Everything practice- and production-grade lives behind Plus / Pro.

Annual vs monthly on Pro?

Annual is $99.99 / year (save 58%) — best value if you're committed. Monthly is $19.99 if you prefer flexibility. Both unlock the same Pro features; cancel anytime.

Does my subscription work on the iOS app too?

Yes. Web and iOS share one codebase split by SKU flag. Sign in with the same Apple ID and your progress, snapshots, and saved Sa carry over.

Where does the pitch math actually run?

Server-side. Always. Your browser ships audio frames to the API and receives back hz / cents / chroma. The YIN code, the raga grammar, the synth engines, the LUFS mastering — none of it ever lives in your tab.

What about teacher mode?

On the Pro roadmap. Local-batch student-drift aggregation — a teacher can see where each student is consistently flat or sharp without their audio ever leaving the device.

Do you store my recordings?

No. Audio frames are processed per-request and discarded. We keep the pitch trajectories you explicitly save (snapshots), nothing else.

Refund policy?

Both editions are in final preparation — join the waitlist at support@karunattu.com and we'll email you the day billing opens. Standard 7-day refund window applies from launch.
