How does the kettle drum make vibrating sounds?

The kettle drum, or timpani, produces sound when the membrane, or drumhead, is struck by a mallet. This impact causes the drumhead to vibrate, generating sound waves. The pitch is determined by the tension and size of the drumhead; tightening it raises the pitch, while loosening it lowers it. The drum's shape also helps amplify the sound, creating the resonant tones associated with kettle drums.
