Web Harmonium
A free browser harmonium for Indian music learners
What it does
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.

Hi Hacker News, I've created Chord Nebula, a simple web-based game designed to help users learn and practice piano chords, basic progressions, and harmony fundamentals. The game integrates with MIDI keyboards, allowing you to play chords in real-time and receive immediate feedback based on the key you choose. GitHub Repository: https://github.com/yottanami/chord_nebula Live Demo: https://chords.yottanami.com Requirements: To use Chord Nebula, you'll need a MIDI keyboard connected to your computer. Current Status: Chord Nebula is still a simple project. I'm…
- APA platform for remote piano lessons based on the Web MIDI API2024 · keyboardconnect.com · ▲224
I'm building a video conferencing app designed to facilitate better remote piano lessons. My hope is to solve a lot of the challenges piano tutors and new students deal with when taking lessons through Skype/Zoom. It leverages WebRTC's data transmission to send media, MIDI state, and (eventually) send sheet music files and other musical data. I'm surprised with how well the MVP has worked and would love to hear any feedback or suggestions!

- JIJust intonation keyboard – play music without knowing music2023 · ad8e.pages.dev · ▲331
This is a keyboard in just intonation. It can play the notes a piano can. The big difference from a piano is that all the notes become consonant. At least, when you want to play a dissonant chord, you are clearly opting in to it because it's clear which notes are dissonant to each other. You won't bump into a dissonant note by mistake. You can play without knowing any music theory. Hit arbitrary notes with the rhythm you want, and the pitches will work. Not understanding the buttons is fine. Even rolling your elbow around your keyboard is fine. If you are a musician and press the wrong key…

Hey HN, Henry here from Cactus. We open-sourced Needle, a 26M parameter function-calling (tool use) model. It runs at 6000 tok/s prefill and 1200 tok/s decode on consumer devices. We were always frustrated by the little effort made towards building agentic models that run on budget phones, so we conducted investigations that led to an observation: agentic experiences are built upon tool calling, and massive models are overkill for it. Tool calling is fundamentally retrieval-and-assembly (match query to tool name, extract argument values, emit JSON), not reasoning. Cross-attention…
