The clarinet is a woodwind instrument played with a single reed. Clarinets come in various sizes, with various pitch ranges. Though there are more than a dozen various modern clarinet types, the most common ones used in orchestras and bands are the B flat and A clarinets. The bass clarinet, which is much bigger than the general and has an upwardly curved bell, is also frequently utilized in modern bands and orchestras. The general clarinet contains five parts—the mouthpiece, the barrel or tuning socket, the upper or lefthand joint, lower or right hand joint, and the bell. A thin, flattened, particularly shaped piece of cane called a reed must be inserted in the mouthpiece before the device can be played. Different notes are produced as the player moves his arms over metal keys which open and close air holes in the clarinet's body. An tool corresponding to the clarinet—a cylindrical cane tube played with a cane reed—was in use in Egypt as early as 3000 B. C. Instruments of this type were used across the Near East into modern times, and other clarinet prototypes were played in Spain, parts of Eastern Europe, and in Sardinia. A folk device found in Wales throughout the eighteenth century, called the hompipe or pibgorn, was very similar to Greek and Middle Eastern cane single reed instruments, but it was made up of bone or of elder wood.
