Circle of Fifths

Chromatic Circle

Click one of these buttons to transpose down or up one half step.

These two discs can be used to tranpose keys. On the left is a circle of fifths within a circle of fifths. On the right is a chromatic circle within a chromatic circle. Click the + button to transcribe to the next higher key (a half step up) or the - button to transcribe to the next lower key. Notice that the inner circle of fifths will tick over five spaces. The inner chromatic circle will tick over one place. Then substitute the chords in the outer ring for the chords in the inner ring. e.g. Click + twice and see the trasposition from C to D.
