It is interesting to have a look into the basic structure of some of these instruments as it reflects a great deal on the musical ingenuity of the folks.
 

Kamayacha is an extremely elegant instrument of the professional singing community of Mangniars all over Marwar. It has a large circular belly covered with parchment, a peg system and a finger board. It has three main strings of gut, besides nine suppletory and four sympathetic steel strings all passing through a broad bridge. The long wooden curved bow of horse-tail hair moving on all the strings is characteristic of this instrument. Used by all singing communities, specially in Marwar but mainly by those belonging to the Langas.








 

 The rawanhatta consists of half a coconut-shell resonator covered with membrane, bound to it with the help of cotton cords, a two feet long bamboo stick fixed to the resonator with two main strings, one of horse-tail and other of steel. In addition to these are sympathetic steel strings varying between three to thirteen, passing over a bridge and them directly to the wooden pegs fixed to the sides of the stick. It is played with a curved bow of horse-tail hair drawn across the strings with rhythmic jerks, the small brass bells attached to it providing the jingling stress on beats. It is held by the left hand, the resonator resting on the left side of the chest. The dexterity lies in playing each successive note clear and detached and synchronising it with singing, changing the rhythm and displacing the normal beats and accents as and when required by the musical situation.



 

Bankia is a trumpet-like brass instrument with an oblong loop-type tube body, a saucer-shaped opening and an integrated mouthpiece through which air is blown in powerfully. It is used with the dhol, mainly by the musicians on all auspicious and festive occasions. Its sound gives a welcome boost to the tempo of the drummer, stirs up and stimulates the singers, provides a refreshing fillip to the dancers, and generally strengthens the overall effect of the musical activity.









 

A favourite of the Langas is the morchang, a wrought-iron instrumetent, much akin to the Jews harp, which produces twanging sounds. Held between the teeth, the left hand keeping it is position, it is played with right-hand fingers plucking the projected tongue, the sound being reinforced by air blown from the mouth of the player. The instrument is capable of producing a variety of notes and weaving a large range of rhythmic patterns.

 

 

A slender instrument used particularly at the time of weddings, is sahnai. A double-beating reed instrument consisting of a single piece wooden tube with a opening and a metal mouthpiece, it is played as an accompaniment to nagara.
