A morsing (also mukharshanku, mourching, morching or morchang, Rajasthani: मोरचंग, Tamil: நாமுழவு அல்லது முகச்சங்கு,Malayalam : ''മുഖർശംഖ്'', English: Jaw Harp) is a wind percussion instrument, mainly used in Rajasthan, in the Carnatic music of South India and in Sindh (Pakistan). It can be categorized under lamellophones, which is in the category of plucked idiophones. It consists of a metal ring in the shape of a horseshoe with two parallel forks which form the frame, and a metal tongue in the middle, between the forks, fixed to the ring at one end and free to vibrate at the other. The metal tongue is bent at the free end in a plane perpendicular to the circular ring so that it can be struck and is made to vibrate. This bent part is called the trigger. An instrument with a history of 1500 years, its exact origin in India is not well documented. In the tradition of the Indian gurukul system of teaching, thus folk tales are a secondary source of its history. In India it is found mainly in South India, Rajasthan and also in some parts of Assam. It is also sometimes used while playing Rabindrasangeet in Bengal and in Assamese folk songs. In South India, it features in Carnatic concerts and percussion ensembles. It is said to be the percursor to subsequent instruments such as the harmonica and the harmonium. In Rajasthan it is called ''morchang'' and is used as a percussion instrument in ''lok geet'' (folk music). It was often used in Hindi cinema by music directors like R.D. Burman and S.D.Burman, and has resurfaced in the twentieth century, with street performers like Varun Zinje playing it in a renewed style. ==Playing technique== The morsing is placed between the teeth and held firmly in the hand and is struck using the other hand to produce sound. Movement of the player's tongue, variations of the throat and blowing and sucking of air through the instrument produces different sounds or overtones. Thus some players use it as a form of practising pranayama. Others speak into the instruments while playing, thus giving it the effect of a light haunting echo. The morsing is firmly held in the hand, the frame or the ring between the palm and the fingers usually in the left hand. Care should be taken to see that the middle part or the metal tongue is not being touched when held idle. Then the upper of the two parallel forks is gently pressed against the front upper teeth; the lower fork, against the front lower teeth, so that the metal tongue will not contact the teeth when it moves. The trigger is plucked with the tip of the index finger. Sound is produced due to the vibration of the metal tongue of the morsing in the mouth and the throat cavity. Movement of the player's tongue with constant plucking can produce very fast patterns of sound. By constricting the space in the mouth and throat many variations of sound can be produced. While traditionally made of iron, variants can be made from wood, bone, and even plastic and credit cards. 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「morsing」の詳細全文を読む スポンサード リンク
