Politonus III Ear Training 4+

Politonus III will create a series of “reverse ear training” exercises in which you must change the music being played into the requested scale.
This is one of the best ear training exercises you can do to improve your ability to recognize scales and modes.

Each half-moon controls a degree in the scale. Click on a moon to toggle between two possible states which will change said degree by a half-step. There will be one to three moons depending on the current level.
You will not know which degree each moon is controlling, nor which state makes the pitch higher/lower.
You must use your ears to figure it out. The sound for the requested scale is represented by the squares below the name of the scale.

Politonus III uses machine learning to create the next ear training challenge based on your progress. It will automatically detect when you are ready to move to the next level.

You will be working on all the modes from the three main source scales:
Ionian: Ionian, Dorian, Phrygian, Lydian, Mixolydian, Aeolian, Locrian

Melodic Minor: Melodic Minor, Dorian b2, Lydian #5, Lydian b7, Mixolydian b13, Locrian natural 9, Altered

Harmonic Minor: Harmonic Minor, Locrian natural 13, Ionian #5, Dorian #4, Mixolydian b9b13, Lydian #9, Altered Dominant o7
