How to Play

This guide covers everything you need to get started with this web harmonium — from basic keyboard codes to advanced raga exploration.

Quick start

Tap the unlock button on the Play page first (or just press any harmonium key — the sound unlocks automatically). After that, use the visible keys on mobile, the mapped laptop keys on desktop, or a connected MIDI keyboard in a browser that supports WebMIDI.

Keyboard codes

The harmonium keyboard maps to your QWERTY layout: e = Sa (C4), r = Re, t = Ga, y = Ma, u = Pa, i = Dha, o = Ni, p = upper Sa. Number keys play the komal/tivra variants (black keys). Each harmonium key shows both the Western note name and the Sargam syllable.

Controls

Volume, transpose, octave, and reverb all update the virtual harmonium immediately and stay saved in local storage for the next visit. Use transpose to shift the harmonium tuning — for example, set transpose to +2 to play in D instead of C.
