About This Instrument

Web Harmonium is a free, ad-free web harmonium — an Indian harmonium that runs entirely in your browser using the Web Audio API. Play it with a laptop keyboard, a touchscreen, or a MIDI controller.

The instrument has been a cornerstone of Hindustani classical music, bhajan, kirtan, and Bollywood playback for over a century. This virtual version brings that tradition online: tune to any key, switch octaves, add reverb, and practise with Sargam notation — all without installing an app.

The goal is simple: keep the harmonium one tap away, and let the rest of the site provide the song notes, raga guides, and practice tools that surround it.
