The ''ranat ek'' ((タイ語:ระนาดเอก), , "alto xylophone") is a Thai musical instrument in the percussion family that consists of 21 wooden bars suspended by cords over a boat-shaped trough resonator and struck by two mallets. It is used as a leading instrument in the piphat ensemble. ''Ranat ek'' bars are typically made from rosewood (''Dalbergia oliveri''; (タイ語:ไม้ชิงชัน); ''mai ching chan'') and they are two types of ranat ek mallets. The hard mallets create the sharp and bright sound, normally used for faster playing. The soft mallets create the mellow and softer tone, used for slower songs. In the Thai xylophone family, there are several similar instrument with bars made from different types of material, such as metal (''ranat ek lek'', ''ranat thum lek'') and glass (''ranat kaeo''). There is another similar Thai xylophone that has a different kind of wooden bar, called “ranat thum”. Its appearance is similar to the ''ranat ek'', but it is lower and wider. It is usually played in accompaniment of a ''ranat ek''. Also, ''ranat ek'' is very similar to the Cambodian xylophone called “roneat ek” .〔(【引用サイトリンク】url=http://www.isaansmile.com/Thai_musical/Project4.7.html )〕 ==History== ''Ranat ek'' was originally an instrument called ''Krap''. A pair of ''krap'' was used to keep the rhythm in ensembles. Later, ''krap'' were put into a series. However the tones when the bars were struck were out of tune. Then it was decided to make a series of ''krap'' on two tracks to support it. After the instrument makers gained some experience and knowledge, the ''krap'' were made in a series of sizes with a track to hold them together making the tone clearer. To make them into a series, a heavy sting was threaded through holes made near the ends of the krap. The krap were placed near each other on this cord and the entire “keyboard” was hung on a supporting stand. Later on, the keyboard was improved using krap and beeswax with lead shavings attached underneath each krap to improve the tone. This whole instrument was called “''ranat''” and the krap which make up the keyboard are called “''luk ranat''”. The whole series of krap or the keyboard is called “''pern''”. At first the keys of ranat were made of two kinds of bamboo, Dendrocalamus Nees (''Dendrocalamus Nees''; Thai: ไผ่ตง; ''phai tong''), and Indian Timber Bamboo (''Bambusa tulda''; Thai: ไผ่บง; ''phai bong''). Later on, different types of hardwood were used, such as rosewood (''Dalbergia oliveri''; (タイ語:ไม้ชิงชัน); ''mai ching chan''), Lakoochaand (''Artocarpus lacucha''; Thai: ไม้มะหาด; ''mai mahat'') or Siamese Rosewood (''Dalbergia cochinchinensis''; Thai: ไม้พะยูง; ''mai pa yung''). Normally Indian timber bamboo is preferred because of its tone. The support of the keyboard is shaped like a Thai riverboat, curving at each end.〔(【引用サイトリンク】url=http://www.thaigoodview.com/library/teachershow/sakaew/sornchai_p/ranad/sec01p04.html )〕 The first Thai instrument ensembles only used one ''ranat'', and this had fewer keys than the ''ranat'' nowadays. More and more keys were added until the ''ranat'' became too large for one stand to hold. So a second ''ranat'' with lower toned keys was created. This was called ranat thum, with the original ''ranat'' with the higher-toned keys being called ''ranat ek''.〔(【引用サイトリンク】url=http://pirun.ku.ac.th/~b5511100242/p2.html )〕 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「ranat ek」の詳細全文を読む スポンサード リンク
