A buddy and I—both music school grads—were frustrated that most music theory apps were either overly basic, dry, or just not that fun. So we built the one we always wished existed: Treble.

Treble is a mobile app that teaches music theory through interactive lessons, quizzes, and ear training games. Whether you're brushing up on Nashville Numbers, trying to recognize intervals by ear, or diving into chords and harmonic analysis, we designed it to be engaging for beginners and seasoned musicians alike.

Features:

- Bite-sized lessons on scales, rhythm, chords, and more - Interactive quizzes and mini-games to reinforce learning - Addictive ear training that actually sticks - Streak tracking

We just launched on the App Store, and would love feedback from fellow musicians, learners, or curious hackers. It took longer to build than we thought, but we’re proud of where it landed—and have a long roadmap ahead.
