단음을 기반으로 한 해금 농현의 특성 분석에 대한 연구

Abstract

Vibrato, called nonghyeon or nongeum , is one of the typical performance
 techniques frequently used in gugak (Korean traditional music). There have
 been studies that analyzed the characteristics of vibrato of vocal and wind
 instruments in the field of gugak . However, there are not many studies that
 objectively analyzed the characteristics of vibrato of haegeum, one of the
 representative Korean traditional string instruments. This study examines the
 characteristics of haegeum vibrato, using strong, medium, and soft monotones
 of haegeum from the digital sound sources provided by the National Gugak
 Center. It analyzes 42 haegeum monotones specifically in terms of intonation,
 vibrato rate, and vibrato extent.
 As a result, the vibrato speed in haegeum is around 4 Hz (four times per
 second), which is generally lower than that in Western music. The vibrato
 extent ranges from 60 cents to 153 cents on average per note, which covers a
 somewhat larger range compared to that in Western music. In addition, there
 are some discussions regarding the tendency for the vibrato rate to increase,
 which appeared at the end of some vibratos, and the results of the vibrato
 extent according to strong, medium, and soft playing in monotones.
 This study is significant in that it has provided basic data on the
 characteristics of the haegeum vibrato, but also has a limitation of analyzing
 only monotones played by a single performer. It is hoped that future research
 will be conducted to analyze the characteristics of haegeum vibrato on various
 pieces performed by multiple performers.
