가곡의 골격음과 핵음 분석

Abstract

In this article, the relationship between the component tones and tonal system in kagok was discussed. Specifically, it analyzes the main and nuclear tones of ujo and kyemyŏnjo not only focusing on the instrument playing or song but on the entire ensemble. As a result, it turns out that the main tones of ujo kagok are ‘㑀’, ‘㑖’, ‘㑣’, ‘㑲’, ‘黃’, ‘太’, ‘仲’, ‘林’, ‘潢’, and the nuclear tones are ‘㑣’ and ‘太’. The main notes of kyemyŏnjo kagok are ‘㑖’, ‘㑣’, ‘黃’, ‘仲’, ‘林’, ‘潢’, and the nuclear tones are ‘㑣’ and ‘仲’. Accordingly, it can be argued that kagok forms its structure centering on two nuclear tones. Since notes in an octave relationship in kagok do not have the same weight in music, this research confirms that it is necessary to analyze the octave relationship separately when analyzing the component tones. The reason why the analysis of skeletal and core notes is important is it tells the musical flow as well as content development of the kagok ensemble beyond the discussion of the tonal system. In the kagok ensemble, the main and nuclear tones are shared by the song and instrument group, and each part forms a heterophony by operating non-main tones more freely and variably.
