Touch-optimized Indian harmonium for iOS & Android.
Practice Sargam notation on the go — no app installation required.
Features
Touch-optimized interface designed for mobile musicians — practice Indian classical music anywhere with your phone or tablet.
Web Harmonium delivers a full seven-octave range rendered through layered reed samples recorded in a concert-hall acoustic environment. Toggle reverb on or off depending on your practice context.
See Sa Re Ga Ma Pa Dha Ni alongside C D E F G A B on every key — simultaneously. The only online harmonium that bridges Indian Sargam and Western notation for every musician.
Powered by the Web Audio API, Web Harmonium processes sound in real time with near-zero latency. No buffering. No lag. Just the harmonium, responding to every touch the way it should.
Plug in any MIDI-compatible keyboard and play with the expressiveness of physical keys. Velocity-sensitive input, multi-device support, and real-time device selection — no additional drivers needed.
Shift your harmonium up or down in semitones instantly. Playing with a vocalist in a different key? One click — done. No retuning, no setup.
A real harmonium vibrates multiple reeds per note. Web Harmonium replicates this through a reed layering system — combining multiple sample recordings per key to preserve the warm, full-bodied tone.

Ragas
Practice authentic Ragas anywhere with Web Harmonium Mobile. Built-in guides for four essential Hindustani classical Ragas — optimized for mobile learning.
One of the most widely taught Ragas and often the first learned by students of Indian classical music. Built on the Kalyan Thaat, it features a raised (tivra) Ma — the defining note that gives Yaman its distinctive, longing quality.
Characteristic: Ma♯ (F#) — the tivra Madhyam that defines Yaman
One of the oldest and most sacred Ragas, Bhairav evokes the stillness of dawn. It features komal Re and komal Dha, creating a deeply meditative interval structure central to temple music and classical khayal compositions.
Characteristic: Komal Re (C#) + Komal Dha (G#) — the morning austere quality
Raga Kafi belongs to the Kafi Thaat and is closely associated with seasonal folk and thumri traditions. Its komal Ga and komal Ni give it a warm, bittersweet quality, often used in light classical compositions and film music.
Characteristic: Komal Ga (D#) + Komal Ni (A#) — bittersweet warmth
Malkauns is a pentatonic Raga — it uses only five notes — yet produces one of the most powerful and otherworldly moods in all of Indian music. It omits Re and Pa entirely, giving it an austere, hypnotic gravity that challenges and rewards advanced players.
Characteristic: Pentatonic — no Re (D) or Pa (G), creating haunting spaciousness
Techniques
Learn authentic Indian classical music techniques on your mobile device — practice Meend, Gamak, and more anywhere.
A smooth, continuous glide from one note to another. In harmonium playing, Meend is simulated through rapid grace notes — a skill that defines the difference between a student and a performer.
A rapid, vigorous oscillation between two adjacent notes, creating a shimmering, urgent sound. Gamak is common in Dhrupad and instrumental compositions demanding power and energy.
A brief, ornamental touch of an adjacent note before landing on the principal note. Kan notes are the punctuation marks of Indian classical phrasing — subtle, but unmistakable when absent.
A gentle, slow oscillation on a specific note — typically komal swaras like komal Ga in Raga Bhairav. Andolan is not a decoration but a structural characteristic of certain Ragas.
