The Kong Mon is different from the Thai Kong in that the framework is of a crescent shape with the ends standing upright. The framework is usually carved and decorated with beautiful glazed reflectors. The method of tying the gongs (Luk Kong) to the framework and the method of playing the instrument are also unique. The Kong Mon is played in the Pii Pat Mon ensemble.
         The Kong Mon has 3 main component parts.
         1. The framework (Raan Kong) is made of 3 pieces of hard wood, i.e. the head, the end and the middle parts. Each part is hollowed out to function as a sound box and assembled together. The outer part of the framework is usually carved, gilded and decorated with glazed reflectors. One end of the crescent framework, on the left hand side of the player, is usually carved to represent the head of a mythical half bird-half man creature called Ginnon, and this end of the framework is called Na Pra. The other end of the framework is carved to represent the tail of the Ginnon. Under the Na Pra and the tail end are fixed with one hoop each for inserting the wooden beam when transporting the instrument. Under the middle part of the framework is a stand made of wood, similar to the stand of the Ranad (Tao Ranad).
         2. The gongs (Luk Kong): There are 15 gongs in the Kong Mon Wong-yai. The gongs are made of molded or beaten metal, in the same methods as the gongs of the Thai Kong. However, the metal may be thinner. A mixture of lead filing and wax is fixed to the underside of each gong to tune the gong into the desired pitch. The gongs are tied to the framework in order of pitches starting from left to right, i.e. starting from Fa, then Sol (skip one pitch), then Ti, Do, Re (skip one pitch), then Fa, Sol, La, Ti, Do, Re, Me, Fa, Sol, and La on the furthest right.
         The missing pitches from this method of tying the gongs are called “Lum” (pit), which is the important identity that produces the beautiful musical sounds and accents when playing the instrument.
         3. The playing sticks of the Kong Mon Wong-yai are made of hard wood turned into a long cylindrical shape, about 25 centimeters long. The head is bound with rope and covered with a piece of cloth.
