Tone Circle

Explore musical tones and chords visually and using your fingers. Find out the names of various chords - from simple to advanced. Play with the tones and understand the relationships in a simple yet powerful way.

The Tone Circle app shows the tones from a single octave in a circle as it is natural to our hearing. You can select some tones and manipulate them via various multi-touch gestures. This way you can visualize the tones that belong to various intervals, chords, or scales and which tones change and which stay in chord progressions.

How to use it:

- drag a selected tone and drop it on some other position to move it
- drag a selected tone away also to unselect it
- transpose the whole chord by pinching and rotating it with two fingers
