Analysis of Pitch and Vibrato in Jeongak Daegeum solo - focused on a solo played by Nokseong Kim Seong-jin -

It has been emphasized that acoustic research is necessary to identify Korean music. such acoustic research has been carried out mainly by the scholars of natural science. A pitch measuring programme has recently been developed, which is always available to the musicologists. NCKTPA asked the acoustic research team of New Media Communication attached to Seoul National University to develop a programme to measure pitch of Korean traditional music. It came out in the mane of nopijaegi 1.0 (pitch astimation program 1.0). I wrote this thesis to prove how this programme can be used for the Korean music research. sangyeongsan, cheongseonggok and gyeongpngnyeon played by Kim seong-jin who was the representative taegeum(cross bamboo flute) palyer of the latter 20th century are partially measured and analyzed for the research of pitch and vibrato of Korean traditional music. The following is the result from the research of the very limited subject. In pitch, even some same tones have different pitches according to the pieces. namryeo (湳, c ) has the biggest difference. It is 1051Hz in cheongseonggok, but it is 1087Hz in gyeongpungnyeon. There is a gap of 58cent(about 1/2 half tone) between those two pitches. Yimjong(林, b) shows the smallest difference. Yimjong in sangyeongsan is 468Hz and that in gyeongpungnyeon is 470Hz and the difference is 7cent. We can understand that the real pitch of same tone of the same player can be different from the fact. When we transcribe hwangjong(黃) as Eb, the pitches of the taegeum jeongak is generally higher than temperament whose a is 440Hz. The pitch of jungryeo (㴢, ab ) in gyeongpungnyeon shows the biggest difference, which is 100 cent higher than the temperament. The lowest tone compared to the temperament is namryeo(湳, bb ) in cheongseonggok, which is 7 cent lower than the temperament bb . The interval is also different according to the pieces. The interval of major second is various from 119 cent to 238cent. The interval of minor third is 317-347 cent and it is wider than that of temperament minor third which is 300 cent. The intervals of 4th and 5th or octave are all wider or narrower than the temperament. Two different phenomenon are seen in vibrating tones. Vibrato appears only in the last part when the tone is of long duration. When the tone is of short duration vibrato appears from the beginning. The wave cycle of the former is 306ms and that of the latter is 270ms. The number of vibrations of the former is 3.3 per second, and that of the latter is 3.7 per second. They differ in amplitude, too. The amplitude of the former is 50 cent and the latter has 74 cent of amplitude.
