If this description seems vague, it is because percussion instruments employ an extraordinary variety of methods to produce sound. The simplest percussion instrument is a pair of clapping hands, while the most complex require extensive mechanical workings.
In general, percussion instruments can be grouped into pitched and unpitched classes. Pitched percussion instruments sounds specific pitches and are therefore able to play melodies and harmonies, while unpitched are used only to sound rhythms.
Pitched Class
Piano
The piano is the most common percussion instrument. Indeed, it is usually classed by itself, for—unlike other percussion instruments—it is played by specialists who perform an enormous repertoire of solo music that has been created for the piano over the past three hundred years. What identifies the piano as a percussion instrument is its method of producing sound. When a player depresses a key on the piano, it causes a hammer to strike a metal string, the vibrations of which produce sound within the wooden body of the instrument. The keyboard is laid out in a way that gives the player access to every pitch of the chromatic scale, while the mechanical action allows performers to control the dynamic level and sustain of each note.
The piano is closely related to other keyboard instruments that are discussed in this book, including the harpsichord and organ. These are described in the context of specific examples.
Mallet Percussion
Most of the pitched percussion instruments are laid out like a piano keyboard, but produce sound when the player strikes a key with a mallet. This in turn causes a metal tube positioned below the key to vibrate and produce sound. The marimba has wooden keys and a large range. Its timbre is mellow and resonant. The xylophone looks similar to the marimba, but it has a smaller range and produces a more articulated and piercing sound. The glockenspiel is smaller still and has metal keys that produce a bell-like sound.
Timpani
The timpani have a long history in the orchestra, and they are arguably the most important instrument in the percussion section. The timpani constitute a set of three to five drums with large copper bowls and taut resonating heads. Each drum is tuned to sound a specific pitch. Although the timpanist seldom plays melodies, the drums are often used to reinforce the harmonic structure of the music.
Unpitched Class
The list of unpitched percussion instruments is nearly endless. One of the most common is the snare drum, which has two taut resonating heads, the lower of which is strung with metal beads that produce a rattling sound. The player uses two sticks to perform rhythms on the upper head. Also common is the bass drum, which likewise has two heads and is played with a large, soft mallet. Various gongs and cymbals are made out of metal and either struck with a mallet or crashed together.
