What Is Web Harmonium?
Web Harmonium is a free online harmonium keyboard that runs entirely in your web browser. Built for Indian classical music practice, it features authentic harmonium sounds. The keyboard covers the seven Sargam notes — Sa Re Ga Ma Pa Dha Ni — across multiple octaves, with both natural (Shuddh) and altered (Vikrit) variants.
The instrument uses the Web Audio API with high-quality samples recorded from real Indian harmoniums. You can also connect an external MIDI keyboard for a more realistic playing experience. Audio processing includes studio-quality reverb — creating a warm, resonant sound on any device.
Whether you're a student exploring Sargam notation for the first time, a teacher demonstrating ragas, or a hobbyist practicing bhajans and devotional songs, Web Harmonium gives you a complete, readily-available instrument at your fingertips. Free to use, and supported on every modern browser and device.
