"Throughout my teaching career, I hauled an entire library of scale books, chord dictionaries, theory manuals, and handwritten charts between schools and student homes. Eventually I asked: Why isn't all of this in one place? That question became Interval Matrix Pro."
Explore Western modes, melodic minor harmonies, harmonic minor, whole-tone, diminished, plus 20 authentic Indian classical Ragas (Bhairav, Todi, Yaman, Marva) and microtonal intervals.
Supports 4, 5, 6, 7, and 8-string guitars, 4-6 string bass, 88-key piano keyboard, violin, viola, cello, double bass, banjo, mandolin, dulcimer, ukulele, and sitar. Build custom tunings on demand.
Stop memorizing blind box patterns. The Matrix assigns consistent colors to interval degrees (Roots, 3rds, 5ths, 7ths, extensions) so you instantly recognize harmonic tension and stability in any key.
Define custom string counts, alter tunings instantly (Drop D, DADGAD, Open Tunings, Baritone), and isolate specific intervals to eliminate fretboard blind spots forever.
