Kettle drums Timpani (also known as kettledrums) are musical instruments in the percussion family. A type of drum, they consist of a skin called a head stretched over a large bowl traditionally made of copper.... They are played by striking the head with a specialized drum stick called a timpani stick or timpani mallet. Unlike most drums, they are capable of producing an actual pitch when struck, and can be tuned, often with the use of a pedal mechanism to control each drum's range of notes. Timpani evolved from military drums http://en.wikipedia.org/wiki/Timpani
