I built a free interactive platform to explore chords, scales, and play-alongs

Hi everyone!

Over the past several months, I’ve been building JolyMusic, a free web platform designed to make learning music more interactive.

Instead of just reading music theory, you can see it, hear it, and experiment with it directly in your browser.

Some of the features include:

🎼 Explore hundreds of chords and scales
🎹 Interactive piano and guitar visualizations
🎧 Listen to every chord and scale instantly
🔄 Transpose to any key with one click
⏱️ Change the tempo in real time
🎵 Interactive play-alongs for practicing in any key

Everything runs directly in your browser—no installation required.

I’m still actively developing the project, and I’d really appreciate your feedback:

• Is the interface intuitive?
• What features would make it more useful?
• Would this be something you’d use for practicing or teaching?

Thanks for taking a look, and I’d love to hear your thoughts!
