That Stays Bright

Learn to Perform

Master intervals, chords, and progressions with integrated ear training. Learn to identify keys, play along with songs, and improvise. Each lesson you complete lights up a star.

Stars Fade Over Time

Just like real knowledge, your stars dim if you don't practice. This shows you what you actually remember vs. what's slipped away.

ABOUT

Hi, I'm Carrie!

I've wanted to learn music theory for years. To hear a song and know what's happening, to jam along without fumbling, and to improvise and actually sound like I know what I'm doing.I tried different apps, but they were either boring, too narrow, or taught theory I couldn't actually use when I sat down to play.So I decided to build something myself.Foolight is named after my dad. Foo (福) means blessing, good fortune. He passed away in October 2025.My dad was brilliant, but due to circumstances, he never got the chance to achieve what he was capable of. It pained me, and that's why I care about education - I want to help people reach their potential.If you've been looking for practical music theory - theory you can actually use to perform - I'm building it.Launching February 2026. I'd love to have you join the waitlist.— Carrie
