There are various genres of musical pieces in Korean vocal music. However, the current elementary music curriculum has limitedly selected some pieces from the genres of folk songs and pansori for in-class use. The genre of japga, a representative of the Gyeonggi-province music, is not covered in the elementary school music textbooks. In the case of long-japga, it is considered a highly difficult piece to learn. On the other hand, Hwimori-japga is deemed appropriate to in-class singing activities and lessons in elementary schools since it has humorous lyrics, simple melodies, repetitious rhythms and beats, and reasonable vocal ranges. This study identified the problems of the current elementary music education through the analysis of the 2015 revised elementary school music textbooks. As a solution, it suggested teaching plans for the singing education of Korean music using ‘Bawi taryeong,’ ‘Bidan taryeong,’ and ‘Maengkkongi taryeong’ from Hwimori-japga. This utilization was developed to meet the criteria of the activities areas required in the 2015 revised elementary school music curriculum. Even if the amount of Korean music has been secured in the textbook, people’s perception of Korean music cannot be improved when the textbook always covers the same repertoire of educational content without any systematic structure. In that sense, it is urgent to develop Korean music songs for in-class use, and it is hoped that this study will be helpful.
