The bones are a musical instrument (more specifically, a folk instrument) which, at the simplest, consists of a pair of animal bones, or pieces of wood or a similar material. Sections of large rib bones and lower leg bones are the most commonly used true bones, although wooden sticks shaped like the earlier true bones are now more often used. If metal spoons are used instead, as is common in the United States, this is called "playing the spoons". The technique probably arrived in the U.S. via Irish and other European immigrants, and has a history stretching back to ancient China, Egypt, Greece, and Rome. They have contributed to many music genres, including 19th century minstrel shows, traditional Irish music, the blues, bluegrass, zydeco, French-Canadian music, and music from Cape Breton in Nova Scotia. The clacking of the loose rib bones produces a much sharper sound than the zydeco washboard or frottoir, which mimics rattling a bone up and down a fixed ribcage. They are typically about 5" to 7" in length, but can be much longer, and they are often curved, roughly resembling miniature barrel staves. Bones can also be flat, for example by the cutting of a yardstick. They are played by holding them between one's fingers, convex surfaces facing one another, and moving one's wrist in such a way that they knock against each other. One method involves placing the bones to either side of the middle finger such that approximately two-thirds of their length extends along the palm while the remainder protrudes above the fingers on the backside of the hand. The hand is held in a loose fist with the bones and the curled fingers roughly parallel to the palm, with the bone closest to the ring finger gently held against the palm by the tip of the ring finger placed on its edge, while the other bone is left free to move in the "hinge" formed by the index and middle fingers as they gently hold it. It is also possible to play the "hinge" on the lower (ring finger) bone while locking the top (index finger) bone against the palm. A player may use a pair of bones in each hand, or just a single pair in one hand. A critical element to playing the bones is not trying to force them to make contact with one another through finger manipulation but allowing their momentum to do the work. By moving the hand back and forth across the chest, with just enough force on the bones to keep them from falling out of the hand, a patient learner can produce a triple click. This "click-it-y" sound is the essential ingredient to playing the bones. A double-click can be produced by the same movement of the hand with the addition of a bit of pressure to the bones to suppress the third click. Once these elemental triple and double figures have been mastered, they can be combined to create complex combinations of rhythmic sounds. The effect is further enhanced by the use of two pairs of bones, one in each hand. A skilled practitioner can produce a wide variety of percussive sounds reminiscent of those made by a tap dancer. The Irish tradition is unique to the island. While North American players are typically two-handed, the Irish tradition finds the vast majority of bones players using only one hand, a distinction in method that has a strong impact on musical articulation.〔Vallely, F. (1999). The Companion to Traditional Irish Music. New York University Press: New York, p. 33-35〕 The comparison of the function of banjo rolls〔Cantwell, Robert (2002). ''Bluegrass Breakdown: The Making of the Old Southern Sound'', p.100. ISBN 0-252-07117-4.〕 with that of bones within an ensemble suggests that stereotypically a subdivided accompaniment pattern is played on the bones. The song "This Old Man" describes bone playing, particularly sheep bone playing (hence paddywhack). ==Sources== 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Bones (instrument)」の詳細全文を読む スポンサード リンク
