Circle of 5ths Virtuoso app for iPhone and iPad

This edition deals with twelve sharps and flats.

The number 12 is a special number in music, possibly the perfect number. In enharmonic keys, twelve numbers make the circle in the abstract that generates an interesting number sequence of 12, 10, 8, 6, 4, 2, 0, -2, -4, -6, -8, -10, -12 in symmetrical shape. This is useful for understanding the circle of fifths and other related issues. Thus, fully comprehending these enharmonic key signatures is important.
