It is arranged in a circular fashion, with the major and minor key signatures listed in a clockwise direction, and the distance between adjacent key signatures representing a perfect fifth interval. The Circle of Fifths is useful for determining the key of a piece of music and for making smooth and natural transitions between key signatures in composition and arrangement.
