Bell Boeing V-22 OspreyVariants
A bell /ˈbɛl/ () is a directly struck idiophone percussion instrument. Most bells have the shape of a hollow cup that when struck vibrates in a single strong strike tone, with its sides forming an efficient resonator. The strike may be made by an internal "clapper" or "uvula", an external hammer, or—in small bells—by a small loose sphere enclosed within the body of the bell (jingle bell). Bells are usually cast from bell metal (a type of bronze) for its resonant properties, but can also be made from other hard materials. This depends on the function. Some small bells such as ornamental bells or cowbells can be made from cast or pressed metal, glass or ceramic, but large bells such as a church, clock and tower bells are normally cast from bell metal. Bells intended to be heard over a wide area can range from a single bell hung in a turret or bell-gable, to a musical ensemble such as an English ring of bells, a carillon or a Russian zvon which are tuned to a common sca ...

Struck Idiophone
Struck idiophones is one of the categories of idiophones (that is, any musical instrument that creates sound primarily by the instrument as a whole vibrating—without the use of Strings (music), strings or Acoustic membrane, membranes) that are found in the Hornbostel-Sachs system of musical instrument classification. Struck idiophones are categorised as 11 in the Hornbostel-Sachs system. There are two main categories of struck idiophones, directly (111) and indirectly (112) struck. According to Curt Sachs, Sachs, Directly struck (111) Directly struck idiophones produce sound resulting from a direct action of the performer as opposed to the indirectly struck idiophones. The player strikes the instrument with a direct action, either by hand or by mechanical intermediate devices, beaters, keyboards, or by pulling ropes, etc. It is definitive that the player can apply clearly defined individual strokes and that the instrument itself is equipped for this kind of percussion.

Bell Tower
A bell tower is a tower that contains one or more bells, or that is designed to hold bells even if it has none. Such a tower commonly serves as part of a Christian church, and will contain church bells, but there are also many secular bell towers, often part of a municipal building, an educational establishment, or a tower built specifically to house a carillon. Church bell towers often incorporate clocks, and secular towers usually do, as a public service. The term campanile (, also , ), from the Italian ''campanile'', which in turn derives from ''campana'', meaning "bell", is synonymous with ''bell tower''; though in English usage campanile tends to be used to refer to a free standing bell tower. A bell tower may also in some traditions be called a belfry, though this term may also refer specifically to the substructure that houses the bells and the ringers rather than the complete tower. The tallest free-standing bell tower in the world, high, is the Mortegliano Bell To ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bianzhong
''Bianzhong'' () () is an ancient China, ancient Chinese List of traditional Chinese musical instruments, musical instrument consisting of a set of bronze bells, played melodically. China is the earliest country to manufacture and use musical chimes. They are also called chime bells. These sets of chime bells were used as polyphonic musical instruments and some of these bells have been dated at between 2,000 and 3,600 years old. They were hung in a wooden frame and struck with a mallet. Using a wooden hammer and a rod to beat the bronze bell can make different pitch. Along with the stone chimes called ''bianqing'', they were an important instrument in China's ritual and court music going back to ancient times. Several sets of ''bianzhong'' were imported to the Korean court during the Song dynasty. Pronounced in Korean as ''pyeonjong'', the instrument became an important part in Korea's ritual and court music and is still in use. In Vietnam, the instrument, which was used in ceremo ...
