This thesis aims to establish foundational data for the field of applied musicology, with a focus on research conducted on practical music in Korea. To accomplish this, an analysis was conducted on the current status of doctoral dissertations related to practical music, categorizing them into practical and popular music. The Department of Applied Music in Korean universities was established in 1988. Although a doctoral program was introduced in 2003, research papers on applied music were not prevalent. There are over 1,500 theses and dissertations related to applied music stored in the National Assembly Library, and individual papers are published in various academic journals. However, due to the difficulty in synthesizing these sources comprehensively, the significance lies in examining the current state of research on applied music, focusing on doctoral dissertations, to establish foundational data for the field of applied musicology. The concept of applied music encompasses a wide range of musical cultures, including popular music, jazz, Eastern traditional music, Western classical music, and others, as defined by the educational objectives of universities. It aims to create “music of the 21st century” by integrating various musical genres. In terms of categorization, an examination of university curricula in South Korea reveals over 100 courses classified under this category. The current status of doctoral dissertations on applied music and popular music reveals that there have been 94 papers (from 1992 to 2024) on applied music, conducted at 23 different institutions. Notably, Kyung Hee University and Sangmyung University have produced the highest number of dissertations in this field. As for popular music, there have been 65 papers (from 1994 to 2023), researched at 33 institutions. Kyung Hee University leads in the number of dissertations, followed by Sangmyung University and Sejong University. These papers were categorized and analyzed based on their content, with 35 focusing on historical aspects, 64 on typology, 41 on effects, and 19 on applications, totaling 159 papers. The nature of these papers covers various topics such as the overall history of popular music, expected outcomes through program development, emotional and therapeutic uses of popular music, as well as papers exploring humanities-related subjects like philosophy and aesthetics. However, there is a scarcity of papers specifically focused on aesthetics and art studies.
