The audio piece entitled "Spin of a Quarter" begins with the distinct sound of a quarter being spun on a hard, flat table surface. The metallic clink of the coin resonates as it twirls rapidly, creating a soothing, rhythmic hum. The pitch and tempo of the spinning quarter fluctuates as it loses momentum, the spinning sound becoming more irregular and choppy. The audio draws to a close with the final, unique sound of the quarter wobbling to a halt, ending its spin with a resonating clatter.
