Whether respiratory muscle training is of benefit to the singing students is controversial. The purpose of the study is to investigate pulmonary function and the maximal inspiratory(MIP) and expiratory pressure(MET), and maximum phonation time in five female singing students before and after the specially programmed respiratory muscle training during 2 months. All singing students had average 4.8 years of formal classical voice training. Respiratory muscle training machine (Ultrabreath) was used to train respiratory muscle. Pulmonary function test data on simple pulmonary function, flow volume curve, static lung volumes are obtained from Vmax 6200. The MIP and MEP were measured using Spirovis, and the MPT were measured using hand-held stopwatch. Any pulmonary function test variables are not changed after respiratory muscle training. However, MIP and MEP were significantly increased between before and after respiratory muscle training. MPT increased significantly after training, compared to the pre-trained. MIP, MEP, and MPT after training in female singing students were 26%, 25% and 33% higher than those before training. The result indicated that the specially programmed respiratory muscle training is beneficial to improve respiratory muscle strength and vocal function without an increment in pulmonary function.

MIP was significantly increased in singers, compared to the untrained group. MIP in patients showed decreasing tendency compared to the untrained group, but were significantly lower than that in singers. MEP in singers was higher than that in the untrained group. MPT increased significantly in singers, but diminished in patients compared to the untrained group. MIP, MEP, and MPT in male singers were 50.8%, 61.0%, and 28.7 % higher than those in female singers. MIP, MEP, and MPT in the untrained male were more increased 32.3%, 25.0%, and 28.7%, respectively than those in the untrained female. There was no correlation between MPT and MIP or MEP. Regression analysis of the data set showed that weight and vocal cord dysfunction was a positive predictor of MPT. Factors affecting MIP were male, singers and weight. Factors affecting MEP were male, singers, vocal cord dysfunction and weight.

Western classical singing voices are different from those of pop song singer's singing voices as well as traditional Korean singing such as Pansori. We anlalysed the singing voices from three different categories with using free application programs available at the usual smart phones : sound level meter and Spectral View Analyzer and fiberoptic rhinolaryngoscopic evaluation. The intensity of voice produced by a classical western singer was 11 dB louder than that produced by a pop song singer. Source sound, glottic sound, as well as harmonic sound and singing resonant sound (Singer's formant) are much more prominent. When evaluated under video-rhinolaryngoscopy during singing, the resonance cavity especially oropharyngeal cavity and hypopharyngeal cavity are widely opened during singing of the western classical singer than those of the traditional Korean singer's singing. Difference of singing methods including producing the glottal sound, respiration and resonance are discussed. Possible explanation of development of 'Singer's Formant' is discussed.

The in-country interest in vocalists is worthy of notice. However, the public, including experts, don't have sufficient information for their interest. In this situation, the popularity of Seth Riggs' books is surprising, because his major is vocal music, not popular music, although he is known as 'a great vocal trainer'. Therefore, we should analyze his vocalization methods and compare them with Bel Canto. His skills are (focused on) SLS (Speech-level singing). The unique styles he used are related to Bel Canto in vocal music, but with some differences. Nevertheless, both styles have something in common. For example, they are similar in that they continue to keep up with the times, so as to improve and evolve. Therefore, it is important for the selected passages to be investigated and presented, based on the individual body conditions and properties. Seth Riggs' vocalization method should be systematically examined too. This is because it has great influence on the public.

This study compared classical operatic singing and applied music singing using the vocal assessment software, Dr. Speech and SPEAD from Lx Speech Studio. Participants in this study included: eight female operatic singers (mean 22.6 yrs, average career 7.5 yrs); eight male operatic singers (mean 25.6 yrs, average career 7.3 yrs); eight female applied music singers (mean 25.1 yrs, average career 6.1 yrs); and eight male applied music singers (mean 27.6 yrs, average career 6.8 yrs). The results demonstrated significantly higher closed quotient values in female applied music singers during singing (p<.05). In addition, higher closed quotient values in speaking were presented in male classical singers and longer MPT was obtained in female operatic singers (p<.05). Furthermore, singer's formants were identified in all male operatic singers and in three female operatic singers. In contrast, only one applied music male and one female singer showed singer's formants while singing.

Background and Objectives : Classical singers are capable of masking abnormalities due to their high level of training and may present with apparent technical deficits rather than with obvious dysfunction. Therefore, some variations from expected normal laryngeal behavior may be present in trained classical singers. Consequently it is important for otolaryngologist to obtain a baseline assessment of their laryngeal function. Materials and Methods : Acoustic measurement including strobovideolaryngoscopy from 50 classically trained singers was done for this study, which was compared with the data from 20 untrained adults. Results and Conclusion : This study showed that 50-healthy asymptomatic classical singers revealed an incidence of 50% abnormal strobovideolaryngoscopic findings, but their acoustic data was within normal limit despite the abnormal laryngeal findings. Therefore the author recommends that the classical singers need objective voice analysis and their baseline data should be used for the accurate diagnosis of the cause of voice dysfunction In classical singer whose baseline laryngeal behavior may be unusual.

An actor should be well-trained at the natural breathing and phonation in order for a good diction. This thesis is focused on the breathing training method at the pre-phonation stage. The past research on the breathing and phonation training was generally for vocal music, yoga, or those which were approached by the medical view point, whereas there are not so many researches which are approached for an acting training even though it is quite important for actors. In addition, such researches have been given an overview of breathing, phonation and diction. Therefore, this thesis which is focused on the breathing training at the pre-phonation stage suggests the natural breathing training method through the imagination and image in the various situations which could exist in the drama.

호흡은 우리가 일상 생활에서 발화나 발성을 하는데 있어서 크기와 높낮이를 조절하는 중요한 역할을 하며 그 중에서 복식 호흡이 가장 이상적인 호흡이라 할 수 있겠다. 우리 인간이 처음 태어날 때는 복식 호흡을 가지고 태어난다. 예를 들면 갓난아이가 울 때 보면 배가 많이 움직이는 것을 볼 수 있으며 긴 시간을 울어도 울음의 소리의 변화가 거의 없다. 허나 성인이 갓난아이처럼 긴 시간을 운다면 울음소리의 변화가 온다. 이것은 우리 인간이 성장하면서 복식 호흡의 사용이 점차 줄고 흉식 호흡의 사용이 보편화되는데 그 이유는 우리 인간의 일상생활에서 복식 호흡이 크게 필요치 않기 때문이기도 하며 특히 여성의 경우는 대부분이 흉식 호흡을 사용하는데 갓난아이일 경우 남아나 여아가 복식 호흡을 사용하나 여아의 경우 성장하면서 즉 여아에서 여성으로 신체적 변화(첫 배란)가 시작되면서 호흡사용의 변화가 있지 않나 생각된다. 여성으로의 신체적 변화는 임신을 할 경우 자궁에서 태아의 성장에 자극을 피하기 위하여 흉식 호흡을 사용하며 성악도인 경우 여성이 남성보다 복식 호흡의 습득에 어려움이 있다 대부분의 여성 성악가의 경우 복식 호흡과 흉식 호흡의 중간을 사용한다.

Due to differences in singing styles and voice production between classical and popular music singers, their knowledge and practice regarding vocal hygiene may differ. This study compared the knowledge and practice of vocal hygiene among 121 university undergraduate students (58 classical and 63 popular music vocal majors). Additionally, the correlation between the level of knowledge and practice of vocal hygiene and the subjective voice evaluation was examined. The results revealed that both knowledge and practice of vocal hygiene were significantly higher in classical than popular music vocal majors, and that vocal hygiene practice was significantly higher than knowledge in the entire group. In addition, there was a weak positive correlation between knowledge and practice of vocal hygiene; and a weak negative correlation between vocal hygiene practice and subjective voice evaluation. This study suggests that popular music vocal majors have relatively lower levels of knowledge and practice in vocal hygiene than classical music vocal majors. It also highlights the need to provide tailored vocal hygiene education programs for both classical and popular music vocal majors, as they show low levels of knowledge and practice in certain aspects of vocal hygiene.
