Claves ((:'klaβes),〔(Online Spanish Phonetic Transcription Converter )—Free Online Tool to convert Spanish Text to IPA Phonetic Transcription〕 Anglicized pronunciation: ) are a percussion instrument (idiophone), consisting of a pair of short (about , thick dowels. Traditionally they are made of wood, typically rosewood, ebony or grenadilla. In modern times they are also made of fibreglass or plastics. When struck they produce a bright clicking noise. Claves are sometimes hollow and carved in the middle to amplify the sound. Claves are very important in Cuban music, such as the son and guaguancó. They are often used to play a repeating rhythmic figure throughout a piece, known as ''clave'', a ''key pattern'' (or ''guide-pattern, timeline patter, phrasing referent'','' bell pattern'') that is also found in African music and Brazilian music.〔Godfried T. Toussaint, “A mathematical analysis of African, Brazilian, and Cuban clave rhythms,” ''Proceedings of BRIDGES: Mathematical Connections in Art, Music and Science'', Towson University, Towson, MD, July 27–29, 2002, pp. 157–168.〕 Among the better known rock recordings featuring claves are the Beatles' recording "And I Love Her," and "Magic Bus" by the Who. Steve Reich's ''Music for Pieces of Wood'' is written for five pairs of claves.〔Steve Reich, ''Writings about Music'', New York University Press, 1974.〕 The Cuban Overture of George Gershwin includes claves. ==Technique== The basic principle when playing claves is to allow at least one of them to resonate. The usual technique is to hold one lightly with the thumb and fingertips of the non-dominant hand, with the palm up. This forms the hand into a resonating chamber for the clave. Holding the clave on top of finger nails makes the sound more clear. The other is held by the dominant hand at one end with a firmer grip, much like how one normally holds a drumstick. With the end of this clave, the player strikes the resting clave in the center. Traditionally, the striking clave is called ''el macho'' ("the male") and the resting clave is called ''la hembra'' ("the female"). This terminology is used even when the claves are identical. A roll can be achieved on the claves by holding one clave between the thumb and first two fingers, and then alternating pressure between the two fingers to move the clave back and forth. This clave is then placed against the resonating clave to produce a roll.〔Karl Peinkofer and Fritz Tannigel, Handbook of Percussion Instruments, (Mainz, Germany: Schott, 1976), 142.〕 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「claves」の詳細全文を読む スポンサード リンク
