                   A DRUM IS A percussion instrument that
                    consists of a drumhead, made of skin or
                    plastic, stretched over one or both ends of
                    a hollow vessel (the body shell). Drums
                    are played in most parts of the world and
                   are made in a number of different shapes
                   and sizes. They can be divided into three               Tension rod

       (e.g., congas). Drums are usually sounded by
       striking the drumhead with the hands or with
       beaters, such as a hard-headed stick. The              Hi-hat

       drumhead vibrates, and its vibrations
       are amplified by the hollow body shell.
       The snare drum has wires—known
       as snares—stretched across the lower
       drumhead; the snares vibrate against
       the lower drumhead when the drum is
                                               Snare
       played. Most drums, such as congas,     drum
       do not have a definite pitch and can play
       only rhythms (see pp. 516-517). Other drums,
       such as timpani, have a definite pitch and can
       play melody, harmony, and rhythms. They can be
       tuned by adjusting the tension of the drumhead.
       Different types of drum can be combined together
       with other percussion instruments to form a drum
       set. The basic components of the drum set are
       bass drum, tom-toms, floor tom (tenor drum),
       snare drum, and cymbals.
