How to read the circle of fifths and understand its significance in music theory?

The circle of fifths is a visual tool used in Music Theory to show the relationship between different keys and their corresponding major and minor scales. It helps musicians understand key signatures, chord progressions, and modulation. To read the circle of fifths, start at the top with the key of C major and move clockwise to find the key signatures with increasing sharps or flats. The circle of fifths is significant because it helps musicians identify key relationships, chord progressions, and create harmonically pleasing music compositions.
