How does the circle of fifths influence the composition and arrangement of music?

The circle of fifths is a tool used in Music Theory to help composers and arrangers understand the relationships between different musical keys. It can influence composition and arrangement by providing a guide for creating chord progressions, modulations, and harmonies that flow smoothly and sound pleasing to the ear. Composers often use the circle of fifths to create a sense of tension and resolution in their music, leading to more cohesive and engaging compositions.
