Web Harmonium is an online harmonium you can play directly in your browser on any Mac. This guide walks you through setting up your laptop harmonium on macOS — from first play to MIDI setup — so you can play harmonium online without downloading anything.

Connecting MIDI Hardware to Web Harmonium

While Web Harmonium supports typing via QWERTY, for the serious practitioner, a MIDI keyboard is essential. MacOS Core Audio provides near-zero latency, which is critical for the rhythmic “bellows” movement of Hindustani classical music on Web Harmonium.

Pro Tip: Airflow Simulation

Use the modulation wheel on your MIDI controller to simulate the opening and closing of the harmonium bellows. This adds dynamic volume shifts that define the instrument's soul.

Web Harmonium Keyboard Mapping & Tactility

Mapping your Mac's QWERTY keyboard to the Web Harmonium Sargam scale allows for laptop harmonium practice even without hardware. We suggest the following standard mapping for a balanced hand position:

ASa (Lower)
SRe
DGa
FMa

Optimizing Web Harmonium Audio Latency

MacOS handles audio differently than Windows. To ensure your Web Harmonium notes trigger instantly, you must configure your buffer size for optimal online harmonium performance.

Common Issues

No sound on Safari?expand_more
Safari requires a user interaction (like a click) before audio can play. Ensure you click the "Start Session" button on the Web Harmonium interface to initialize the AudioContext.
Stuck notes (MIDI Hang)expand_more
If a note continues to play after releasing the key, use the "Panic" button in the Top Right of the tool or press the Spacebar twice quickly.
