Hey Product Hunt! 👋 I built Web Harmonium because I couldn't find a decent harmonium practice tool that actually ran in a browser — every option was either a clunky download or a pale imitation of the real sound. The harmonium is the heartbeat of Indian classical music, bhajans, and qawwali — but if you don't own a physical one, practicing is a real challenge. So I built a virtual version that uses real instrument samples processed through the Web Audio API for authentic tone and reverb. What started as a personal practice tool evolved into something more complete: 🎹 Full Sargam (Sa Re Ga Ma) notation on every key 🎛️ MIDI keyboard support for external controllers 🔊 Studio-quality impulse response reverb 📱 Works on desktop, tablet, and phone — no install needed 🆓 100% free, no sign-up, no intrusive ads https://web-harmonium.com Whether you're a student learning your first raga, a vocalist checking pitch, or a teacher demonstrating scales — Web Harmonium is ready in seconds. Would love to hear from Indian classical music enthusiasts, educators, and world music lovers. What features would make this even more useful for your practice? 🙏
