From Intervals to Chords: Your Instinctive Piano Companion

A smarter and more intuitive way to explore harmony, built for musicians, students, and curious learners who want to visualize and understand chords in real time.

Instinctive Chords shows you the chord you’re playing instantly. Play notes on a MIDI keyboard and see the chord name update in real time, so you can quickly confirm what you’re actually playing. No guessing, no theory gymnastics.

If you want to go deeper, the app also shows the intervals and note relationships inside each chord, helping you understand why it works, not just what it’s called.
