인간의 가장 원초적인 예술의 시작은 낙서와 막연한 두드림 이였다고 이야기한다. 낙서가 미술이라는 계열로 발전, 승화했다면 두드림의 의미는 음악 이라는 계열로 발전하여 오늘에 이르게 된다. 인간의 두드림으로 시작한 행위가 음악의 시초였다면 당연히 인류의 원초적 악기는 타악기라고 봐야 마땅할 것이다. 타악기는 각 민족의 문화와 풍습 또는 시대에 따른 사용처에 따라 날로 발전하고 다른 모습으로 변모해왔다. 인류가 만들어 낸 이 수많은 타악기들은 각각 스스로를 필요로 하는 음악에서 연주되어지고 있다. 이 중에서도 "Drum set" 라는 악기는 다른 타악기와는 조금 다른 특성을 띠게 되는데, 바로 여러가지 타악기군이 조합하여 한 명의 연주자에 의해 복합적인 리듬을 만들어낸다는 데 있다. 이 Drum-set 에 구성된 각각의 악기들은 재미있게도 독자적인 역사를 가지고 있는데 본 논문은 이 구성된 타악기들을 분석하며 아울러 이 악기가 음악에 미치게 된 영향까지 연구하는데 초점을 맞춰본

관성 센서는 외부 장치의 도움 없이 3차원 공간상에서 움직임 측정이 가능하다. 최근 MEMS 기술의 발달로 소형 저가 관성 센서(가속도 센서 혹은 각속도 센서) 제작이 가능해져 관성 센서를 소형 휴대 기기에 내장하여 사용자의 움직임을 감지하거나 의도 파악하는 연구가 진행되고 있다. 본 연구에서는 관성 센서가 내장된 휴대 기기를 이용하여 3차원 공간상에서 6가지 위치에 따라서 각기 다른 6가지 소리를 발생하는 가상의 멀티 타악기 시스템을 제안한다. 즉, 휴대 기기를 상/하로 흔들면 가상 타악기의 타점 위치에 왔을 때 비트 음을 발생하고, 6개의 다른 위치를 구분하여 다른 타점의 위치에서 휴대 기기를 흔들면 각각 그 위치와 미리 지정된 소리가 발생하도록 하였다. 이러한 가상의 멀티 타악기 시스템을 위해서 3차원 공간상에서 실시간으로 사용자의 움직임을 감지하고 휴대 기기의 위치를 파악하는 것이 필요하다. 저가의 관성 센서를 이용하여 사용자가 휴대 기기를 움직이는 동작이 있는 상황에서 실시간으로 휴대 기기의 위치를 추정하는 것은 쉽지 않지만 본 연구에서는 다양한 사용자의 움직임 동작 분석을 통하여 사용자가 가상의 멀티 타악기를 상/하로 흔드는 동작을 감지하고 다른 위치로 이동하는 동작을 구분하였다. 개발된 동작 감지 알고리즘과 위치 구분 알고리즘을 휴대 기기에 적용되어 실제로 가상의 타악기 시스템을 구현하였다.

Pyeon-gyeong, similar to Chinese Bianqing, is a Korean traditional lithophone with multiple stone chimes. Due to the temperature- and humidity-insensitive characteristics of its material, pumice stone, the instrument provides highly stable pitch and therefore has played a key role in Korean traditional court music. By reason of having absolute pitch, it is an important part of the research on the standard pitch and scale system of korean traditional music, but as an instrument, the study on the sound characteristics and worth is not making satisfactory progress, to date. This research is an analysis paper for physical modeling synthesis of pyeongyeong. Through this study, we will determine the original characteristics of the timbre of pyeongyeong as a unique korean traditional percussion, and investigate these characteristics objectively, based on the music acoustics by scientific analysis. Furthermore, this study will be used as an important basic material for physical modeling synthesis of pyeongyeong, and also make a huge contribution to the cultural applicability by the vitalization of graft onto the various artistic creation field, through the comprehension of the timbre of pyeongyeong as an instrument.

The positive effect of percussion instruments can induce increases in self-esteem and decreases in depression in the elderly. Based on this, the content for a percussion instrument robot that the elderly can use to play music is developed. The elements of the interaction between the elderly and the robot through the robot content are extracted. Music that arouses positive memories in the elderly is selected as part of the music therapy robot content in order to relieve depression, and a scoring system for playing music is constructed. In addition, the interaction components of the robot's facial expressions, which stimulate emotions and sensitivity in the elderly, are also designed. These components enable the elderly to take an active part in using the instrument to change the robot's facial expressions, which have three degrees of emotion: neutral-happy, happy, and very happy. The robot is not only a music game machine: it also maximizes the relief of depression in the elderly through interactions with the robot that allow the elderly person to listen to what the robot plays and through the elderly person becoming involved and playing music along with the robot.

The purpose of this study was to examine how a therapeutic drumming intervention would impact middle school students with regard to school violence prevention. Participants were all in the third-year class of a middle school in Korea. A school music teacher and a music therapist designed and implemented the program collaboratively, and mainly used dyadic, synchronized, and improvisational drumming based on the Social Emotional Learning core competencies. A total of 65 students participated in a weekly 45-minute program for 10 weeks. Ten participants out of 65 were selected for interviews and the rest of the 55 participants were asked to fill out an open-ended survey. Content analysis of the survey and interviews produced 492 meaningful statements, which were categorized into seven themes: somatic responses to drumming, emotional processing, group cohesion, empathy, relationship with peers, self-esteem, and self-regulation. The findings indicated that dyadic, synchronized, and improvisational drumming may promote prosocial behaviors in students of this age. The author discussed that drumming produces physical input directly from the instruments, which prompts students to identify and empathize with their own or others' emotions. This study therefore suggests that collaborative work between school music teachers and music therapists may positively impact middle school students' prosocial behaviors, as they pertain to school violence in Korea.

This study investigated the effects of traditional percussion improvisation to hearing-impaired college students who are under stress. For the research, between 21 to 22 years old four hearing-impaired college students, who could do lip reading, were chosen. In quantity program, improved version of college student stress measuring method which invented by Gyoung-gu Jun and Gyo-hyeon Kim(1991) were applied, and graphs has been used for analysis. In quality program, for reliability, the researcher and two music therapists observed and analysed it. The period of research was from Dec 26, 2007 to Feb 21, 2008. There were total twenty sessions and two sessions were assigned for each week. One was 40 minutes individual session, and the other one was 50 minutes group session. Even though auditory function is critical in music playing or listening, this study showed the positive results of the therapeutic use of music on stress management for college students with hearing impairment. Future studies are important to continue to investigate the effectiveness of music therapy for hearing impaired clients who are under stress with various age range.

The purpose of this study is to measure the effect of musical activities on children's aggressiveness using percussion playing through case studies and to present the therapeutic programs. Musical activities using percussion playing were organized for three aggressive children. Twenty-one small group sessions were conducted over seven weeks with 30 minutes given each session. Fourth-grade children involved in using Aggressiveness Measuring Tool for Teachers-revised by Gwak Geum-Joo(1992) was selected for case studies. Children's impulsiveness was also tested through self-test measuring tool for impulsiveness-revision of 16 questions used by Cho Hae Yeon (2001) and Lee Joo Shik (2003). As quantitative method, comparative analysis was made between the pre and post test results using measuring tools for aggressiveness and impulsiveness of children as well as between aggressive behaviors occurring in the initial stage of the first three sessions and in the latter stage of the last three sessions. Qualitative method was used at the same time to examine the effect of percussion playing on children. After the musical activities, child A showed reduced Aggressive Measuring Tool scores from 19 to 18, with child B from 23 to 19 and child C from 21 to 18. The results show that occurrence of aggressive behaviors were lowered in the post test. Impulsiveness Measuring Tool scores in the post test were decreased as well in all three children. During the music therapy programs, it was also observed that the frequency of the target behaviors in all three children has reduced more in the latter stage than the initial stage of music therapy. The qualitative findings indicate that the children experienced releasing stress through self-expression after percussion playing. These findings indicate therapeutic effectiveness of music therapy using on percussion playing in reducing aggressiveness of children as well as the effectiveness of percussion as a therapeutic intervention for aggressive children. These results can be adapted and reapplied by teachers in primary schools to approach children with behavior problems, and can present a useful therapeutic approach to therapists practicing in clinical environments.

The purpose of this study is to grasp how B la Bartok's 'Music for Strings, Percussion and Celesta' was expressed in 'Stretto House' of Steven Holl. In conclusion, it is found that phenonenological temporality was expressed through the following equation: (equation omitted). More specifically, it is clarified that the stretto of the musical piece was expressed in the spatial overlapping of the house; the inversion, in the form change of the plan and section of the guest house; the symmetrical proportion and Golden Section, in the same proportion of the house section; the melody of theme, in the shape of the roof. This shows the possibility of approach to the substance of interior and architectural design through music.
