## What is Politonus III (Ear Training)?

Politonus III will help you improve your ability to identify scales and modes from the most important source-scales:
Ionian (Major), Melodic Minor, Harmonic Minor.

This app uses machine learning to create the next exercise based on your progress. Politonus III will create a series of “reverse ear training” exercises in which you must change the music being played into the requested scale. Each half moon controls a degree in the scale. Tap on a moon to toggle between two possible states which will change that 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 scales and modes included the app are:
Ionian (major) and all its modes: Dorian, Phrygian, Lydian , Mixolydian , Aeolian , Locrian
Melodic minor (and all its modes): Dorian b2, Lydian #5, Lydian b7, Mixolydian b13, Locrian n9, Altered
Harmonic minor (and all its modes): Locrian n13, Ionian #5, Dorian #4, Mixolydian b9 b13, Lydian #9, Altered Dominant o7

Your goal is to move all these modes from the unfamiliar zone into the proficient zone. Politonus III will help you achieve your goal in no time.
The Politonus apps were designed by musicians for musicians.

### 1/5 — Fix bugs

*2025-07-29*

July 29 2025 bug erasing all progress every time still not fixed

### 1/5 — Doesn’t work on iPad

*2024-06-09*

Only displays one moon, always in the center regardless of which degree of the scale it is supposed to be affecting. Also, quitting the app doesn’t stop the music playing: you either have to delete the app or shut off the iPad.

### 1/5 — Sound doesn’t work

*2021-01-28*

Was great for about 3 days, then the sound just stopped working. Even after deleting the app (along with my progress) the sound does not work.

### 4/5 — Sound is now fixed

*2020-09-18*

Good value

### 1/5 — No sound

*2020-07-04*

Great concept, excellent for building your ear for modal jazz. However, the app has a bug that doesn’t let it play any sounds.

### 1/5 — Sound doesn't work

*2019-12-18*

Sound doesn't work and I don't see any easy tech support. I'd love to use this and revise my rating.

### 2/5 — Good app until sound stopped working

*2019-10-28*

I was really enjoying this app until the sound stopped working in it about two weeks ago.

### 4/5 — Good and nice but a little thing missing.

*2019-07-26*

This app is nice and very interesting but not pedagogical enough for beginners like me.
For this reason and to improve it would be good to be able to play notes of the keys to listen and better understand... and would be easier when you do not have a keyboard next to yourself.
Thanks for your work.
