For the successful implementation of the 2015 Revised Music Curriculum, namely a competency-based curriculum, practical methods such as competency-based selection of teaching-learning activities and competency-centered instructional design should be promoted. The study aims to examine the meanings and elements of subject-specific competencies in music represented in the music curriculum and interpret subject-specific competencies in music from a Korea music education perspective to ensure subject-specific competencies based music education. On this ground, it proposes a process of selecting subject-specific competency-based teaching․learning activities for Korean music and presents some of the specific examples of teaching․learning activities. The result of examining the meanings and elements of subject-specific competencies in music indicated that it was difficult to directly apply them to class because they are too general and comprehensive. In particular, research on the meanings and elements of competencies in Korean music education is relatively insufficient, so a Korean music education perspective is needed to interpret the meanings and elements of subject-specific competencies. To interpret competencies from a Korean music education perspective is to reinterpret the meanings indicated by competencies in relation to Korean music To this end, the descriptions of subject-specific competencies in music are divided into means and objectives, and each content is interpreted from a Korean music education perspective. Also, some of the sub-elements of competencies that reflect the characteristics of Korean music are illustrated for detailed interpretation. Based on the interpretation of subject-specific competencies in music from a Korean music education perspective, teaching-learning activities for Korean music are selected to cultivate subject-specific competencies in music. The study proposes that selection of teaching and learning activities is made through a four-step process: “identifying grounds, selecting contents and methods, selecting activities, and analyzing competencies.” Step 1 is to identify the basis of activities in the music curriculum, and step 2 is to select contents and method based on the ground of step 1. Step 3 and 4 are to select teaching learning activities and analyze related competencies based on the interpretation of subject-specific competencies in music from a Korea music education perspective. Cases of teaching- learning activities utilizing the interpretation in this process are presented by each area. Competencies have a connective and integrated nature, so the analysis of competencies regarding the cases of teaching-learning activities for Korean music is done in an integrative manner. In conclusion, the study suggests that when teachers design a lesson for Korean music, they should keep in mind that specific teaching and learning activities are not directed at any particular competency, yet relevant competencies change depending on a teaching and learning method. This paper is expected to improve the quality of Korean music education according to the 2015 Revised Music Curriculum.
