Description

Method of manufacturing Korean traditional musical instrument daegeum and daegeum manufactured thereby The present invention relates to the daegeum, a transverse wind instrument and a proud traditional instrument of the Republic of Korea, and more specifically, to a method of manufacturing a daegeum using wood other than bamboo. The daegeum is a traditional Korean musical instrument with a history of approximately 1,300 years. It is the largest and has the most unique structure compared to other transverse wind instruments in the world, and it is a proud traditional instrument whose structure has remained unchanged for over a thousand years. Traditionally, bamboo was used as the primary material for manufacturing the daegeum. Among these, a special type of bamboo called Ssangoljuk was used; because Ssangoljuk grows densely, it was the optimal material for making the instrument, as the inner diameter could be drilled uniformly using drilling machines. However, double-jointed bamboo is not commonly found, and even when found, it must undergo a maturation process of at least five years to harden enough to be used for making musical instruments. Recently, it has become difficult to obtain double-jointed bamboo in Korea, and the supply has reached a state of depletion, leading to a situation where it is harvested from Japan and imported. However, even though the bamboo grown in Japan is double-jointed, there is a problem in that the wood is not hard and is brittle due to differences in climate and environment compared to Korea. To address these issues, Korean Registered Patent No. 10-0298678, regarding a method for manufacturing a daegeum, proposed a conventional method in which bamboo strips were cut into planks, bonded to form square timbers, and then machined to form a hollow cylindrical daegeum body. However, this method still had the limitation of requiring the use of bamboo, and there was a problem in that bonding and processing were not easy due to the characteristics of bamboo. In addition, as another method, the daegeum was manufactured using an injection molding process with synthetic resin, but it had the disadvantage of not being able to produce the deep sound characteristic of bamboo. Figure 1 is a drawing illustrating a bamboo daegeum manufactured in a conventional manner. FIG. 2 is a diagram illustrating the flowchart of a method for manufacturing a large metal drum according to one embodiment of the present invention. FIG. 3 is a drawing for explaining a method for manufacturing a large metal plate according to one embodiment of the present invention. FIG. 4 is a drawing illustrating a daegeum manufactured by a daegeum manufacturing method according to one embodiment of the present invention. Specific embodiments of the present invention will be described in detail below with reference to the drawings. However, the concept of the present invention is not limited to the presented embodiments. Those skilled in the art who understand the concept of the present invention may easily propose other inventions that are inferior or other embodiments included within the scope of the concept of the present invention by adding, changing, or deleting other components within the same scope of the concept, and such are also to be considered to be included within the scope of the concept of the present invention. Additionally, the terms used in this invention are used merely to describe specific embodiments and are not intended to limit the invention. Singular expressions include plural expressions unless the context clearly indicates otherwise. Throughout the specification of this invention, the term 'comprising' any component means that, unless specifically stated otherwise, it does not exclude other components but may include additional components. Figure 1 is a drawing illustrating a bamboo daegeum manufactured in a conventional manner. The conventional method of manufacturing the daegeum involves collecting double-jointed bamboo that is about 4 cm thick and at least 3 years old during the winter, drying the collected bamboo, roasting it over a fire to remove the sap, and heating the bent parts to fix them in a mold to straighten them out, thereby manufacturing the daegeum tube. Next, a straight hole is drilled through the inside of the double-jointed bamboo, followed by the drilling of holes in the order of the mouthpiece, seven-star hole, finger hole, and sound hole. At this stage, each hole is initially drilled small, and then finely adjusted in size using a carving knife. Next, after all the holes are drilled, the bamboo is coated with red paint to prevent internal corrosion, the bamboo tube is wrapped with nylon thread to prevent the bamboo from splitting, and finally, a membrane called a "cheong" is attached to the holes and covered with a "cheong cover" to manufacture the daegeum. This conventional method of manufacturing the daegeum has the disadvantage that not only is it difficult to harvest double
