Rabab Tuner: Instrument-specific tuning and raga practice on Android
Detects subtle frequencies for melody, drone, and sympathetic Rabab strings and converts hummed phrases into fret-specific notation, all on-device. Developed by Key for Business Pty Ltd for Android, the app pairs a precision pitch engine with a practice suite and an adaptive headstock UI. It bundles a metronome, raga-focused scale trainer, and an instrument health check, so students, players, and luthiers get targeted practice tools and maintenance guidance without account sign‑in.
The app targets the Rabab and its unique string layout
Rabab Tuner is built around the Afghan Rabab’s architecture: it recognises melody strings (Katay, Bam, Zer), drone strings (Shahtar), and up to fifteen sympathetic strings. The interface redraws an on-screen headstock and pegboard to match five- or six-peg instruments, which makes tuning and string identification match your physical instrument rather than forcing a generic chromatic view.
Works entirely on-device and respects privacy
The app runs audio analysis locally, so tuning and transcription don’t require network access; the developer explicitly states there are no user accounts, no ads, and no tracking. You can record a short phrase for the Song to Notes preview and keep that work on your device, with an optional internet use limited to a weather Forecast feature rather than core functions.
The interface and workflow focus on practice and maintenance
You navigate between tuning modes, the practice room, and Instrument Health Check; the practice suite includes a metronome, listening trainer, and raga scale exercises named for Bilawal, Kafi, Bhairavi and others. The health check monitors resonance and sustain over time to suggest when strings need attention, which adds a maintenance workflow useful to players and luthiers.
Transcription accuracy and targeted training for traditional repertoire
The Song to Notes tool transcribes hummed or recorded audio into sargam or Western notation and identifies the string and fret to play each note, which supports learning and repertory transfer. The developer reports the pitch engine is tuned to the Rabab’s harmonic profile, and community feedback notes accurate results and a clean, ad-free experience for niche players.
A practical gateway for Rabab learners and craftspeople
If you play or repair the Afghan Rabab and want a focused, privacy-first mobile companion, this app makes traditional practice and upkeep approachable on a device. It suits students who need raga drills and performers who want targeted tuning; luthiers get measurable sustain data. If you prefer a general-purpose chromatic tuner, this specialised approach may be narrower than necessary.
