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. ... the capital letters represent the corresponding major keys. the lowercase letters represent the corresponding minor keys.
The circle of fifths is a way to visualize the twelve musical keys and put them in a convenient order. It's used in music to help remember the notes that make up each key and group similar keys based on the notes that they share.
The circle of 5ths is an arrangement of the 12 notes of the musical alphabet in a circle. ... At the top of the circle we begin on the note C. As you go clockwise around the circle, the notes move in perfect 5ths. A perfect fifth above C is G, and G is the next note on the circle going clockwise.
The circle of fifths is a useful method for organizing key signatures and the progression of sharps and flats. The progression of sharps and flats follows the circle. We begin at the top of the circle with C major (zero sharps and zero flats).
