Circle of Fifths

The order of the notes B - E - A - D - G - C - F (or F - C - G - D - A - E - B) is represented by the circle of fifths. It can also be called a circle of fourths as the distance of two consequent notes is either a fifth or a fourth depending on whether we are counting intervals upwards or downwards.

A circle of fifths with note names proceeding counter-clockwise is seen below. The notes inside the blue circle are root notes: others are altered notes based on the root notes.

In the innermost circle, we can see lowered note names for keys with flat signs (Bb-Eb-Ab and so on). In the outermost circle, we can see the respective raised note names for keys with sharp signs.

The lines (F-B and F sharp-B) describe transferring from one "orbit" to another to keep the perfect fifths. The diatonic circle may build on the harmonic notes of a key, for example: I – IV – VII – III – VI – II –V – I.
