Practice studios for every Carnatic instrument.
5 practice studios live · 2 more on the way.
Each practice studio is built around the specific physics of one instrument — the bowed string feels different from the struck membrane, the breath embouchure is its own thing. Pick the one you actually want to learn. Not sure? The quiz below takes 30 seconds.
Vīṇā
IntermediateThe queen of Carnatic instruments. Plucked, fretted, deeply meditative.
Open practice →
Vāyalin

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.

Pick an instrument
Vīṇā, vāyalin, veṇu, mṛdaṅgam, ghaṭam — five seconds of tapping to find what fits you.
Take the 30-second quiz → - 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 → - 03
Follow a 5-minute lesson
Karunattu listens. It shows you where your pitch is in cents, and compares your gamaka to a reference master.

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.
Reference-calibrated timbres
Voice (MSS), Vīṇā (Chitti Babu), Violin (Lalgudi), Flute (Mali), Nāgasvaram (Chinna Moulana), Mṛdaṅgam (Umayalpuram Sivaraman). Spectrum-regression tests lock the match within ±2 dB per octave.
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.
One app, three tiers
Free anonymous, Plus Sādhaka, Pro Kalākar. Your teacher on your phone, your studio in your browser, your progress in your account. Sa follows you.

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.
Kampita
kampita
A rapid shake between two pitches. The signature ornament of Lalgudi's violin style.
Āndōlan
āndōlan
A slow, wide oscillation — gentle, sustained, the vocal gamaka par excellence.
Sphurita
sphurita
A very fast, small-amplitude shake on a single pitch. Subtle ornamentation.
Jhārā
jhārā
A quick, slightly meandering glide up to the target note. Common in prayōga.
Instrument synth calibrated to
- Lalgudi G. Jayaraman— violin
- M. S. Subbulakshmi— voice
- T. R. Mahalingam— flute
- Chitti Babu— vīṇā
- Sheik Chinna Moulana— nāgasvaram
- Umayalpuram K. Sivaraman— mṛdaṅgam
Spectrum-regression tests lock every synth within ±2 dB per octave of the reference.
Featured
Six ragas to start with.
Every raga ships with ārōhaṇa, avarōhaṇa, signature phrase, mood and a primary-source citation. The catalogue has 79 more.
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.
