The Music System Visualizer lets you explore multiple tuning systems inside one visual and sonic interface.
You can load one or two systems, inspect their interval positions on a wheel or inline view, compare degrees, play themes, hear chords, and measure areas of closeness, beating, or tension.
The page is designed as a comparative listening lab, connecting interval structure, perception, beating, harmonic stability, degree combinations, and instrument color.
It is useful for studying the gap between 12-TET, just intonation, historical temperaments, or custom systems while keeping immediate visual and auditory feedback.
