Sur Tuner: Swara & Tanpura

Sur Tuner is a precision Indian Classical Music pitch visualizer and authentic Tanpura drone companion, crafted specifically for vocalists and instrumentalists. Whether you are doing your daily vocal riyaz or tuning an instrument, Sur Tuner replaces clumsy chromatic guitar tuners with a beautiful, geometrically aligned circular Swara dial rooted in the Indian musical tradition. Experience studio-grade pitch estimation and continuous acoustic Tanpura accompaniment—100% offline, zero latency, and completely ad-free. ━━━━━━━━━━━━━━━━━━━━━━━━━━━━ WHY SUR TUNER? ━━━━━━━━━━━━━━━━━━━━━━━━━━━━ Standard western chromatic tuners display frequencies against western 12-TET equal temperament and pitch names (C, D, E) that don't reflect the relative tonic system (Adhara Shadja) of Indian classical music. Sur Tuner calculates pitch relative to your selected Sa (Tonic), accurately mapping frequencies to Indian Swaras (Sa, Re, Ga, Ma, Pa, Dha, Ni) with microtonal Cent precision based on natural ratios and 22 Shrutis. ━━━━━━━━━━━━━━━━━━━━━━━━━━━━ KEY FEATURES ━━━━━━━━━━━━━━━━━━━━━━━━━━━━ ✦ REAL-TIME CIRCULAR SWARA DIAL Watch your voice or instrument align with the circular pitch gauge in real time. Features an ultra-smooth, responsive needle that pinpoints your pitch accuracy instantly. ✦ CONTINUOUS REAL TANPURA DRONE Enjoy a seamless, warm, resonant acoustic Tanpura drone loop (Pancham Sa-Pa tuning) across all 12 pitch scales (C, C#, D, D#, E, F, F#, G, G#, A, A#, B / Safed & Kali). Perfect for undisturbed riyaz and meditation. ✦ BILINGUAL SWARA NOMENCLATURE Toggle seamlessly between Devanagari script (सा, रे, रे, ग, ग, म, तीव्र म, प, ध, ध, नि, नि) and English transliteration (Sa, Re, Ga, Ma, Pa, Dha, Ni) with a single tap. ✦ MICROTONAL INTONATION & CENT METER See your exact intonation deviation in cents (-50 to +50 cents) with intuitive color feedback: • Green: In perfect tune (Sur) • Amber/Red: Flat (Komal) or Sharp (Teevra) ✦ SAPTAK (OCTAVE) INDICATOR Automatically detects and displays the correct octave range: • Mandra Saptak (Lower Octave) • Madhya Saptak (Middle Octave) • Taar Saptak (Higher Octave) ✦ PITCH STABILITY RIBBON Analyze pitch consistency and steady-note holding with the live pitch stability ribbon.
