## What is Politonus II (Ear Training)?

Politonus II is a music ear training tool that uses machine learning to adapt exercises based on user progress in identifying intervals, triads, and seventh chords. It utilizes a visual interface where musical elements are represented as spheres that transition from 'Unfamiliar' to 'Proficient' as users improve. The app focuses on 'reverse ear training' where users must identify specific musical structures hidden within a sequence of three spheres.
