Instead of hitting the drumhead with a stick, he rhythmically slides a damp cloth along the wooden rod, creating the instrument's unmistakable deep, pulsing sound. The cupa cupa, also known as the putipù, consists of a cylindrical resonating chamber covered by a tightly stretched membrane with a wooden rod passing through its center. As the damp cloth grips and slides along the rod, friction causes it to vibrate, transferring those vibrations to the membrane and producing the drum's characteristic low-frequency tones. The cupa cupa has been part of Southern Italian folk traditions for generations, especially during festivals and celebrations. Its unusual friction-based design demonstrates how simple materials and mechanical vibration can create a rich musical sound unlike that of conventional percussion instruments.
