Chorus Global is a free, community-oriented platform providing music education tools for teachers, students, musicians, and community educators everywhere. We are not a corporation. We are not funded by advertising. We are built on the belief that tools should be free and communities should be honest with each other.
If you choose to Stay Connected, we collect your name and email address. That is all. We do not collect browsing data, device information, or behavioral data. Every tool is fully functional without any account.
By joining the Chorus Global community you are consenting to hear from us about: new tools and features, causes we support including our connected work with humanist schools and community organizations internationally, partners we trust who align with our values, and opportunities to be part of what this becomes.
We will never sell your data. We will never share your email with third parties for their own marketing. We will never spam you. Every email has a clear opt-out. Leave anytime.
Chorus Global is a launching point for a broader community that includes music educators, mutual aid practitioners, community organizers, and people connected to international education and food security work. By joining you are not just signing up for a tool — you are joining a chorus.

who got tired of watching the hungry pay the house.
Chorus Global started as a simple idea: every tool that musicians need to learn, practice, and release their work should be free. Not free-with-a-catch. Not free-until-you-need-the-real-thing. Free.
The platform was built in Maine by an Army veteran and autodidact who taught himself from a 1976 Encyclopedia Britannica — and who has spent years watching the music industry extract value from people who have none to spare. The tools here exist to undermine that extraction, systematically and permanently.
Chorus Global has deep roots in music education internationally, including connections to humanist schools and community programs in Kasese, Uganda. The platform is designed to work offline, on low-bandwidth connections, and on donated hardware — because the world's best musicians are not always the world's most resourced.
This is not a startup. There are no investors. There is no exit strategy. Chorus Global is infrastructure — built to outlast any single person's involvement and to remain free regardless of what the industry does next.
Every tool here was built with care, tested against real use cases, and designed to respect the person using it. No data is collected. No behavior is tracked. No email is required. Your work is yours.
If Chorus Global has helped you — with a lesson, a release, a song, a performance — we ask only one thing: pass it forward. Tell another musician. Use the tools. Make something.
Every tool on Chorus Global is built around the same principles: free to use, private by design, and yours to keep.
Nothing is tracked. We do not use analytics, advertising pixels, or behavioral tracking of any kind. We do not know which tools you use, how long you use them, or what you create with them. Your creative process is not our data.
Nothing requires an account. Every tool works fully without signing in. The Stay Connected option exists for people who want to hear from us — it is never a requirement to access anything.
Your saved sessions stay on your device. Tools like the Release Builder can save your work locally using your browser's built-in storage. This means your data never leaves your machine and is never transmitted to any server. The tradeoff is that saved sessions are device-specific — if you switch from your phone to your laptop, your saved data does not follow you. Clearing your browser data will also clear any saved sessions. We think this is the right tradeoff: genuine privacy over seamless sync.
The tools work offline. After your first visit, Chorus Global installs as a Progressive Web App and caches its tools locally. Most tools — chord finder, tuner, metronome, piano, scale reference, Release Builder, and more — work without any internet connection. The Song Packager requires a one-time download of browser-side processing tools (~31MB), which are then cached for offline use. The World Music Map and Sheet Music Library require a connection to load map tiles and external scores.
The code is open. Chorus Global is licensed under the GNU Affero General Public License v3.0. Anyone can read, share, and build on it — but no one can take it, modify it, and sell it without releasing their changes under the same license. The full license is included with every deployment. We believe tools should be free and that freedom should be legally protected.
This site supports browser translation. Chorus Global is written in English but is designed to be used everywhere. If your browser offers to translate the page — Chrome, Edge, and Safari all do this automatically — accept it. The tools work fully in translation. We do not block or override your browser's translation feature.
What we cannot guarantee. Browser storage can be cleared by the user, the browser, or the operating system — especially on mobile devices with storage pressure. We recommend keeping your own copies of important work. Chorus Global is maintained by a small team and offered without warranty. If something breaks, tell us.
Chorus Global runs on care and stubbornness. If you want to help keep it alive and growing, a voluntary contribution means more tools, better offline support, and expanded reach into under-resourced communities.
