Politonus II will help you improve your ability to identify intervals, triads and sevenths, in no time, by using machine learning to create the next exercise based on your progress. Every music interval, triad and seventh chord is represented by a sphere. As you improve your ear training skills, the spheres will move from the Unfamiliar area towards the Proficient area. Politonus II will create a series of “reverse ear training” exercises in which you must find the requested interval, triad or seventh hidden inside one of three spheres. The spheres will play in sequence. As soon as you know where the requested interval is, “double-tap” on the correct sphere to submit your answer. Politonus II include all intervals, triads and seventh chords. The different levels include: Melodic Intervals / Same Root Harmonic Intevrals / Same Root Melodic Intervals / Different Roots Harmonic Intervals / Different Roots Melodic Triads / Same Root Harmonic Triads / Same Root Melodic Triads / Different Roots Harmonic Triads / Different Roots Melodic Seventh Chords / Same Root Harmonic Seventh Chords / Same Root Melodic Seventh Chords / Different Roots Harmonic Seventh Chords / Different Roots
