## Description

Tonality Visualizer is an interactive polar-pitch map that displays musical notes on a rotating disk.
You can connect a MIDI keyboard or open a MIDI file — every note appears in real time.
The app helps you see harmony, motion, and chord relationships, even without formal music theory.

Main Features
•MIDI Input: visualize notes directly from your keyboard or MIDI device.
•MIDI File Playback / Trainer Mode: play or practice chord by chord.
•Live Sound Option: enable/disable the built-in synth for input playback.
•Physics-based Disk Rotation: the disk moves naturally according to musical torque.
•Simple UI: switch between water-fixed / disk-fixed anchors, toggle UI visibility, bilingual JP/EN.

Perfect for music learners, creators, and anyone who wants to “see” sound.
