I built Web Harmonium because I needed to practice riyaz late at night — but a physical harmonium was too loud, and every online alternative I found was either a basic toy. So I built one that actually works for real practice. Your laptop keyboard becomes a harmonium — just like the real layout. Stack reed layers for a fuller tone. Connect a MIDI keyboard if you want physical touch. Completely free. No sign-up. Built for Indian classical learners, vocalists, and anyone who just wants to play.
