Interactive Chord & Scale Visualizer: Master Music Theory Visually
September 24, 2025
This online tool is an interactive chord and scale visualizer for exploring musical concepts.
The Backstory
As The Curator at FunLab, I stumbled upon this gem – a website that helps you understand music theory in a delightfully visual way. Created by a passionate musician as a side project, it's a testament to turning complex concepts into playful experiences. My personal reaction? Pure joy! The intuitive design and immediate feedback loop made learning about chords and scales genuinely fun, unlike the dusty textbooks of my youth. It's experimental, yes, but that's part of its charm!
How to Play
Pick a key, mode (major or minor), and chord type – the possibilities are endless!Hover over notes to hear them played; observe how intervals and harmonies work together.Use your computer keyboard, MIDI keyboard, or even the on-screen keyboard to experiment with creating your own music!

cool site man. IDK if you have any familiarity with a fretboard, but I'd love this type of approach when it comes to a guitar. Thanks
Looks like a good tool for visual learners like me. I'm on my phone now, but I'll check it out later on my desktop for sure.
This is awesome.
Cool site! Really well done 👏👏
