Interval Matrix Pro

Interval Matrix Pro - Visual Music Theory for Guitar, Piano, Bass & More
Stop memorizing shapes. Start seeing music.

Interval Matrix Pro is a powerful visual music theory app for guitar, piano, bass, and multi-instrument musicians. Instantly see scales, chords, modes, and intervals across instruments using a unique color-based system that makes music theory intuitive, fast, and musical.

Instead of dense theory books or memorized box patterns, Interval Matrix Pro uses a high-contrast 12-color interval matrix that reveals the geometry of music in real time.

Your eyes navigate.
Your ears create.
