Abstract

The characteristics of the vibrato of danso, one of the wind instruments in Korean traditional music, have not been studied much. In this study, the characteristics of the vibrato of danso were analyzed using monotones and musical performances. In particular, intonation, vibrato rate, and vibrato extent were measured as a function of time, and their average values for each vibrato tone were also calculated. The results for vibrato rate showed that the vibrato tended to start slowly and then increase very quickly and significantly and the average values for each tone were observed to have a very wide range, which shows that the characteristics of the vibrato of danso are different from those in Western music. In addition, monotones and musical performances showed some different results in vibrato rate and vibrato extent. There have not been many studies that have quantified the intonation, vibrato rate, and vibrato extent in Korean traditional musical instruments, and this is especially true in the case of danso. The results in this study can be used as basic data on danso vibrato. For example, they can be used as reference materials in education, danso virtual instruments, and danso applications.

국악의 관악기 중 하나인 단소의 요성, 즉 비브라토의 특성은 연구가 많이 되지 않은 분야이다. 본 연구에서는 단음 및 연주곡 음원을 이용하여 단소 비브라토의 특성을 분석하였다. 이를 위해 비브라토음들에 대해 시간에 따른 intonation, vibrato rate, vibrato extent 값을 측정하였고, 비브라토음별로 평균치도 산출하였다. Vibrato rate 결과에서는 비브라토의 속도가 느리게 시작된 후 빠르고 크게 속도가 증가하는 경향을 보였으며, 음별 평균치들은 매우 넓은 범위를 가지는 것으로 관측되었는데, 이상의 결과는 서양 음악과 차이가 있음을 보여준다. 또한, 단음과 연주곡은 vibrato rate와 vibrato extent 결과에서 다소 차이를 보이는 것으로 나타났다. 국악기에서 비브라토의 intonation, vibrato rate, vibrato extent의 결과를 수치화하여 제시한 연구는 많지 않았으며, 단소의 경우는 더욱 그러하다. 본 연구에서 제시한 결과는 단소 비브라토에 대한 기초 자료로써 활용될 수 있을 것이다. 예를 들어, 단소의 비브라토와 관련된 교육이나 단소 가상 악기, 단소 어플리케이션 등에서 참고 자료로 활용이 가능할 것으로 기대된다.
