How to Play the Harmonium Online in Three Steps
The sequence is intentionally simple — get playing first, customize only when needed.

Open and Play
The instrument is live the moment the page loads. Press any mapped key or click a key on screen.
02
Set Your Tonic
Use Transpose and Octave controls to lock the harmonium into the right key center for your voice or raga.
03
Shape Your Sound
Blend reed layers and add reverb only when you want more depth. MIDI mode is there for longer sessions.
