FifthCircle vs Politonus III (Ear Training) Usage & Stats

Convert between musical key and musical key signature using the Circle of Fifths. You can convert either from the other. Keys are selected by tapping on the piano keyboard graphic. Key signatures are selected by tapping on the rotate buttons above the musical staff graphic. Tapping on a piano key will select that key and display the major and minor key names and the key signature for that key. Ambiguous cases (C Sharp versus D Flat for example) are resolved by presenting a dialog where you can select your choice. Tapping on the counterclockwise rotate button will move counterclockwise on the Circle of Fifths. For example from the key of C you will rotate left to one flat (Key of F). Another tap will rotate to two flats (Key of B Flat). Tapping on the clockwise rotate button will move clockwise on the Circle of Fifths. From the key of C you will rotate right to one sharp (Key of G). Another tap will rotate to two sharps (Key of D). Regardless of which direction you are moving around the Circle of Fifths, if you continue tapping you will eventually return to where you started. On the Quiz tab you can practice your key signature recognition for both treble and bass clefs. You can also practice note recognition with the Ear Training option.

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.
