Chord charts that play along with you

Every chord lights up at the exact moment it's played — no more guessing when to switch, no more scrolling with your pinky mid-song. Just watch, play, and stay in the pocket.

Free to play along, always. Creator plans from $3/month. Built by one guitarist who got tired of bad tabs.

↑ The actual experience — each chord lights up in time, and stays lit so you never lose your place.

“The chords are rarely in the correct position relative to the words — makes it hard to know when to switch.”

Fixed. Every chord is pinned to a moment in the song, down to 0.1 seconds.

“I'm fumbling with the mouse mid-song just to keep my place.”

Fixed. The chart scrolls itself, and your hands stay on your instrument — optimized for phone too. Need a song around the campfire? Done.

“Every site shows different chords — which one is right?”

Fixed. The community votes, comments, and perfects every chart together — making perfect chord charts is the whole point of Chordinates.

A note from Rees, the guy who built this

I had this idea over fifteen years ago. My first versions were made frame-by-frame in Adobe Premiere — each chart took 30 to 40 hours. The musicians I played with loved them, but there was no way I could make more than a handful.

I bought chordinates.com back then and kept paying for it every single year, holding onto the dream that one day I'd figure it out. I tried and failed more times than I can count.

It is honestly a surreal dream to see it live as a real app today.

Chordinates is just me — a musician, a dad teaching his son to play, and someone who refused to give up on an idea. When you join, you're not subscribing to a faceless company. You're helping a real person make the world a little better through music. I read every message: tell me what you think →
