Habitual speaking fundamental frequency (sF0) plays an important role in determining the voice classification, which can be presented differently depending on the vocal fold length and language habits. The purpose of this study, therefore, was to compare the differences in sF0 for voice classification and closed quotient between speaking and singing. Seventeen singers (7 sopranos, 5 tenors, 5 baritones, mean age 25.1 years) with no evidence of vocal folds pathology were participated. sF0 and closed quotient (CQ) both in speaking and in singing (A3-A5 with soprano, A2-A4 with tenor and baritone) were measured using SPEAD program and electroglottography. No significant differences were observed for sF0 between tenor and baritone groups (p> 0.05). However, CQ in singing was significantly different among three groups (p< 0.05), but CQ in speaking was not (p> 0.05). Furthermore, CQ was significantly different with both soprano (p< 0.01) and tenor groups ((P= 0.02) whereas baritone group revealed there is no difference when compared between speaking and singing. No significant differences in sF0 between tenor and baritone participants may result from decision-making for voice classification by experience and should measure sF0 before determining the voice classification.

Western singers voice have been studied in music science since the early 20th century. However, Korean traditional singers voice have not yet been studied scientifically. This study is to find the physiological and acoustic characteristics of Pansori singers voices. Western singers participated for comparative purposes. Ten western singers and ten Pansori singers participated in this study. The subjects spoke and sung seven simple vowels /a, e, i, o, u, c, w/. An analysis of Glottal image was done by Scope View and acoustic characteristics of speech and singing voice were analyzed by CSL. The results are as follows: (1) Glottal gestures of Pansori singers showed asymmetric vocal folds. (2) Singing vowel formants of Pansori singers showed breathiness based on Spectrogram. (3) Music formant of western singers appeared in around 3kHz area, however, Pansori singers formant appeared in low frequency area. Modulation of vibrato showed 6 frequency per sec in case of western singers. Pansori singers showed no deep modulation of vibrato on spectrogram.

소프라노는 여성 소프라노 중 가장 높은 음역 대의 목소리를 구사한다. 소프라노들은 고음을 유지하기 위해 턱 관절 과 얼굴근육이 경직되어 있어 입을 크게 벌리지 못한다. 발음 특성은 발성 시의 입의 크기에 가장 큰 영향을 받으며 좋은 발음 특성일수록 뚜렷한 포만트를 나타낸다. 본 논문에서는 소프라노 가수들의 발음 특성을 확인하기 위해 한국의 소프라노 성악가 A, B, C, D 4명을 선정하여 비교한 결과 소프라노 A의 스펙트럼에서 2kHz 이상에서 까지 뚜렷하고 균일한 포만트가 나타났다. 따라서 소프라노 A의 발음 특성이 가장 우수한 것을 확인할 수 있다.

일반적으로 가창을 위한 호흡법으로는 두 가지를 들 수 있다. 가슴의 횡격막 부분을 사용하는 복식호흡법과 배꼽 밑 부분의 아랫배를 활용한 단전호흡법으로 나눌 수 있다. 일반적으로 윗배를 사용하는 복식 호흡법의 경우 주로 성악 발성에서 사용 하였으며, 아랫배를 활용한 단전호흡법의 경우 창이나 판소리 등의 국악 창법에 많이 사용되었다. 상대적으로 역사가 짧은 대중음악의 경우는 특정한 호흡법이 없고 누구에게 배웠느냐에 따라 호흡하는 방법이 결정되었다. 그러나 매스미디어가 발전함에 따라 대중음악 분야도 발전하게 되었고, 대중가요 가수들을 위한 독창적인 호흡법도 절실히 필요하게 되었다. 따라서 본 연구에서는 가창력을 증진 시킬 수 있는 효과적인 호흡법을 제시해 보고자 한다.

노래를 부르는 가수에게 있어 가장 중요한 부분은 정확한 음정과 박자이다. 그와 더불어 중요한 부분이 바로 발음인데, 노래라고 하는 것이 멜로디와 가사말로 구성되어 있기 때문에 발음이 불명확하면 내용이 전달되지 않기 때문이다. 성악이나 판소리의 경우 사전에 충분한 훈련을 통해 음정, 박자와 더불어 발음부분까지 충분히 숙지하는 경우가 대부분이지만 대중음악부분은 모든 가수들이 충분한 훈련 기간을 거쳐 데뷔하는 경우가 많지 않기 때문에 상당부분 미숙한 것이 사실이다. 그중에 가장 소홀히하는 부분이 발음인데, 노래에 멋을 부린다고 하기엔 발음이 너무 과하거나 왜곡되게 표현되는 부분이 많다. 본 연구에서는 노래를 부를 때의 정확한 발음법과 노래의 느낌을 살릴 수 있는 효과적인 발음법에 관해 연구해 본다.

The Korean pop music people enjoy today is mostly based on the pop music from foreign countries. Therefore, not only is the history very short, but also not much research is done in the Korean pop music field. Especially in terms related with the singing method, in other words the breathing and vocalization of Korean singers, it is difficult to define where it is actually situated. To add a little, it seems as if it is swarming somewhere in the middle of Korean traditional music singing methods and classical music vocalization. As pop music made its way into Korea, Korean singers had to go through many trial and errors to sing the songs of singers that had different physical conditions. Singers getting vocal nodules because of excessive vocalization, was not a surprise at that time. Yongphil Jo, a Korean singer, wanted to overcome his limits and maximize his vocal abilities. He found the answers in Korean traditional music. One of his representative songs, "The lady out the window", is one of Jo's title songs and it is the song that made a turning point in the Korean pop music vocalization. The purpose of this research is to understand the circumstances of Korean pop music through the periodical and musical background of the past and find out why the song (The lady out the window) was such an epochal vocal method at that time. Moreover, this paper covers how the breathing and vocalization is expressed by analyzing the flow, the emotional expressions, and the techniques of "The lady out the window."

Background and Objectives: The purpose of this study is to investigate the change of vocal tract length according to the level of the pitch by the singers. Materials and Methods: Fifteen tenors were asked to produce successive /a/ sound in G4(382Hz) for the head register, C3(131Hz) for the chest register and usual speaking sound. The control group consisted of 15 males of an similar age who are not professional singers. The length of vocal tract was calculated by applying the formula of Fn=(2n-1) c/4L(F : formant frequency, c : the speed of sound in the vocal tract(350m/sec), L : length of vocal tract, $n=1,2,3,4,{\ldots}{\infty}$). Results: In singer's group, there showed no significant statistical difference of length among head and chest register and usual speaking sound. However in the control group, there showed statistically significant difference of length. Comparison of the absolute difference in the length of vocal tract by changing level of pitch in phonation, between the control group and the singers group. Changing from G4 phonation to C3 phonation and C3 phonation to usual speaking sound showed statistically difference of vocal tract length was less in the singers group than the control group. Conclusion: The change of vocal tract length, in either speaking or singing, was less in singers than the control group. We could assume that the singers maintain their larynx position constantly throughout the pitch range when phonation.

Background and Objectives : Training of breath support and laryngeal muscles control are important components in the development of the singing voice. The purpose of this study is to compare characteristics of respiratory and phonatory control on pitch, loudness, register change with untrained males and trained male singers. Materials and Methods : The 11 untrained males and 11 trained male singers participated. Closed Quotient(CQ), fundamental frequency (fo) and relative volume contribution of the rib cage (in percentage rib cage, % RC) and relative volume contribution of abdomen (in percentage abdomen, % AB) were measured during various pitch, loudness, register tasks using /a/ vowel phonation : Legato, staccato with C3-D3-E3-F3-G3 notes and crescendo and decrescendo with C3 note as well as modal register with C3 and falsetto register with C4 note using an integrated analysis system of Respiration, EGG and Voice. Results : (1) When pitch increased with legato task, loudness also increased in untrained male group but maintained in trained male singers. CQ was also increased both untrained and trained male singers but it was not significantly different ($p>.05$). The abdomen contribution to lung volume were significantly predominant both in inhalation and exhalation in trained males singers ($p<.05$). (2) When pitch increased with staccato task, CQ was not significantly different in untrained but significantly different in trained male singers. The respiratory function of male singers were characterized by significantly predominant abdomen contribution to lung volume in exhalation except for inhalation ($p<.05$) (3) When loudness increased with crescendo, fo was significantly increased with increasing CQ in untrained males but fo was relatively consistent with increasing CQ in trained male singers. The respiratory function of male singers were characterized by significantly predominant abdomen contribution to lung volume in exhalation except for inhalation ($p<.05$). (4) Most male singers were able to change register from modal to falsetto register, but untrained males were not. Thus, CQ was significantly different between modal and falsetto register in trained male singers ($p<.05$). The respiratory function of male singers were characterized by significantly predominant abdomen contribution to lung volume in exhalation except for inhalation ($p<.05$). Conclusion : Male singers were superior to untrained males in coordination of respiratory and phonatory control on pitch, loudness, register change. Implication are offered regarding how the results might be applied to the voice therapy as well as singing training.

The purpose of this study is to understand the characteristics of contemporary vocalization and songs in order to learn various vocal methods in musical vocal classes and apply them to students. Musical vocalization methods change and evolve according to the demands of the times. Today, the characteristics of contemporary musicals cannot be limited to anyone genre, and the genre of music as well as the style of work are derived from several genres and coexist. 'The Girl in 14G,' the subject of this study, is a song that appeared in the album of Kristin Chenoweth, a famous American musical actress who uses various vocal techniques. Jeanine Tesori composed this song with various vocal techniques such as Classical, Jazz, Belting, and Mixed Voice to express New York's representative music genres of Broadway Musical, Metropolitan Opera and East Village Jazz. The development of the song consists of a difficult process in which one actor has to act across three different characters in three musical styles and singing methods. Singing 'The Girl in 14G' requires a lot of effort and practice as it is necessary to acquire various vocal techniques, which makes it a good text for students and actors in the educational perspective. As a result, this study confirmed that this song is a representative piece with a solid musical and dramatic composition and is a good example that shows the convergence characteristics of contemporary musical vocal techniques.

This study attempted to investigate vocal characteristics and differences in gender and voice classification among classical singers. Twenty-three female singers (M = 23.1 yrs, SD = 3.6 yrs, average 6.3 yrs singing experience, all classified as sopranos) and twenty male singers (M = 25.2 yrs, SD= 3.6 yrs, average 6. 3 yrs singing experience, 8 tenors, 12 baritones) were recruited to participate in the present study. Speaking fundamental frequency (FO), closed quotient (CQ), MPT (Maximum Phonation Time), breathing types, maximum inspiratory pressure (MIP), maximum expiratory pressure (MEP), and singers' formants were measured. In addition, vibratory patterns were observed using stroboscopy. Sfo, singing CQ, breathing types, formant frequency in singers' formants, MIP, MEP, and MPT were significantly different from gender to gender. Generally, singers' formants were observed in male singers and also the pattern of singers' formants was different between tenors and baritones. Lower singing CQ values were observed than speaking CQ values in the female singers (P<.001). Furthermore, MEP, MIP, and singing CQ were significantly lower for female singers than for males singers (P<.001). MPT and speaking FO, however, were not significantly different between tenors and baritones.
