Which are the only drums that have a pitch and therefore capable of playing melodies?

The only drums that have a pitch and are therefore capable of playing melodies are the Timpani. Timpani are a set of tuned drums that are often used in orchestras and marching bands. They are made of a metal bowl with a skin stretched over the top, and they are tuned by adjusting the tension of the skin. Timpani are capable of playing a wide range of pitches, and they are often used to play melodies, accompaniment, and special effects.
