Description
Quinterval is an interactive circle of fifths including the display of the corresponding scales.
A key in the circle can be selected either by touching the tonic or by turning the slider in the middle. The circle displays both the respective major and parallel minor scales. The display ranges from F-flat major (D-flat minor) to G-sharp major (E-sharp minor). A second slider can be used to move the visible circle section accordingly.
The note names can be set between german, english or italian notation.
The lower area shows the related major scale with its key signature. The first step and the sixth step with the corresponding minor scale are highlighted. The notes can be displayed with G-Clef, C-Clef or F-Clef. The accidentals can also be displayed before the individual notes.
Additional functionality is available as an InApp purchase:
- Display the notes of the parallel minor scale
- Display triads with their chord names
- Playback notes by tapping on them

Ratings and Reviews
Looks useful
How does this work?
Could use some in-app instructions & explanations.
Great app
This is a great app for learning the circle of fifths/fourths in music theory. Each position on the wheel also shows each note of the major scale in that key. The only issue is that there appears to be a bug on the Gb position of the circle. Sometimes it shows up as Gb, other times as F#. This position seems to have a mind of its own. Tapping the position sometimes changes it back and forth, other times it doesn't. There was no way to provide feedback to the developer but it is otherwise a very useful app.
Key signatures
This circle of fifths is incomplete. It does not contain all possible key signatures. It would be an excellent app if it had all the key signatures.
