Read full description

Konnakol is a practice app for the South Indian rhythmic solfège tradition — reciting patterns of syllables (sollu) over a tala (rhythmic cycle), the foundation of Carnatic rhythm. LESSONS 22 guided lessons build from "what is a tala" to genuine advanced cross-rhythms: every gati (tisra, misra, sankirna...), talas beyond the basic cycle, "second speed" density, and a preview of the tihai cadence — including lessons that let you hear a phrase drift across a steady beat instead of just subdividing it faster. PRACTICE A configurable tala/nadai metronome with independent phrase length, so you can recite a pattern that resets every beat, or one that runs continuously across the beat grid for real polyrhythmic practice. EXPLORER Build your own jati combinations and audition them in a loop — a sandbox for exploring korvai-style phrases. REAL VOICE, REAL TABLA, REAL DRONE Syllables are recited with real recorded voice samples, not synthesized speech. Switch to a tabla voice for a different color, or layer in an ambient tambura drone — each with its own volume control. HAND POSITIONS Watch the tala's clap, wave, and finger-count hand positions animate in sync with the beat, so you can learn the physical gestures alongside the syllables. Works entirely offline. No account, no ads, no data collection, no permissions requested. FEATURES • 22 progressive lessons, from basic tala counting to advanced cross-rhythms • Adi Talam, Rupakam, Misra Chapu, and Khanda Chapu, with adjustable nadai and phrase length • Real recorded syllable samples (not synthesized speech), with natural pitch/volume variation and subtle reverb • Animated hand positions (clap/wave/finger count) that follow the beat, just like a live performance • Switch between recited voice and a tabla voice for the same syllables • Ambient tambura drone for authentic accompaniment • Independent volume control for click, voice, tabla, and drone • Practice tools for exploring any tala/nadai/phrase-length combination freely NEW: AUv3 PLUGIN Konnakol now ships with its own Audio Unit (AUv3) instrument, so you can run its tala engine directly inside GarageBand, Logic Pro, AUM, and other AU hosts: • Tempo sync with your host's transport, or set your own • Real MIDI output — record the performance onto a Software Instrument track • Local preview button to audition before recording • One-tap randomizer for tala, nadai, phrase length, and voice • The same animated hand-position guide, built into the plugin's own panel Whether you're a music student learning rhythm fundamentals, a percussionist studying Carnatic music, or a producer looking for an unusual rhythmic texture, Konnakol brings this centuries-old tradition to your practice room — and now to your DAW.
