About
Hi — I'm Mike. I'm a software engineer and I play piano for fun. I built GlyphScore because I couldn't find a single free tool that did everything I wanted in one place: open a file, play it, adjust it, print it — Guitar Pro and MusicXML, with real per-track playback, a mixer, tempo and looping, and both notation and tablature, right in the browser.
So I made it, and it's free. No account, no setup, no catch — open a file and you're going in seconds. Your scores stay on your device; nothing is ever uploaded.
If GlyphScore is useful to you, you can buy me a coffee — completely optional, and it helps keep the project going. Either way, I hope it helps you make music.
— Mike
Good to know
- What is GlyphScore?
- GlyphScore is a free, browser-only viewer and player for Guitar Pro and MusicXML scores. Open a file and you get notation and tablature, real per-track playback, a mixer, tempo control, and A–B looping — no backend, no account, no install.
- Which file formats does it support?
- Guitar Pro 3 through 8 (.gp3–.gp5, .gpx, .gp) and MusicXML (.musicxml, .xml, .mxl).
- Is it really free?
- Yes — completely free, with no account and no sign-up. If it's useful to you, you can buy me a coffee, but that's entirely optional.
- Do my files get uploaded anywhere?
- No. Parsing, rendering with AlphaTab, and audio playback all happen in your browser. Your files never leave your device — there's no server to send them to.
