The purpose of this study is to review the contents of the Korean traditional music dictionary and suggest matters to be preserved and supplemented when integrating and expanding online dictionaries. Pungryu music was formed as a music that was later stacked in the Joseon Dynasty and was transmitted to the present, resulting in derivative songs during the process of stacking. Therefore, intuitive presentation of appropriate content every time is essential. In the case of ancient scores, the data should be presented directly in accordance with the content to be used as data for the establishment of private transformation and uniqueness. If it is reversed to staff notations, it is necessary to organize the contents of the dictionary so that people around the world can understand the connected music. If it is Korean music that can be reputed as a staff notation, it should be interpretable so that people around the world can understand it. And, if the issues between the two sides, such as the derivative relationship of other music, are still unresolved, it is necessary to organize the relationship between the two songs into a "correlation" rather than a "causation" and reveal their grounds or sources. There are also differences in the data integration method, as each author has a different focus. At this time, it seems desirable to choose a step-by-step and diffusion-type narrative method based on the music contents according to the purpose of the music dictionary. The unified dictionary, which provides objective data and integrates, will also help Korean music to be listed as a UNESCO World Heritage site in the future.
