Circle Of Fifths

• 
• In music theory, the circle of fifths is the relationship among the 12 tones of the chromatic scale, their corresponding key signatures, and the associated major and minor keys.
• In classical music from Western culture, a fifth is the interval from the first to the last of five consecutive notes in a diatonic scale. The perfect fifth (often abbreviated P5) spans seven semitones and for example the interval from C to G is a perfect fifth, as the note G lies seven semitones above C.
• Starting at any pitch, ascending by the interval of an equal tempered fifth, one passes all twelve tones clockwise, to return to the beginning pitch.
• Legenda: Circle of fifths showing sharps and flat in each 12 keys.
