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.

각 나라마다 고유한 음악이 있으며 또한 그 음악을 표현하는 전통적인 방식이 존재한다. ㄱ러나 서양음악의 도입으로 우리음악의 표현까지도 서양화가 되어있다. 전통음악을 원형대로 보존하기 위해서는 선조들이 사용하였던 기보법을 사용하는 것이 올바른 일이라고 여겨지므로, 우리나라의 전통악보 중 그 우수성이 인정되는 정간보를 컴퓨터를 통하여 편리하게 처리 할 수 있는 시스템을 개발하였다. 정간보에는 악기마다 서로 다른 표현 방법들이 존재하므로, 이번 시스템은 그 중에서 단소를 위한 처리를 주된 목표로, 컴퓨터를 이용한 기보법과 오선보로의 변환, 그리고 마디신호로의 변환과 연주를 중점으로 개발하였다.

Sample design is studied to estimate the number of records from singing rooms. The definition of survey population, stratification, sample size and allocation of sample are discussed with using the collected real data. The validity of sample design is testified by the log data collected from online singing room which is sampled with suggested design. Estimation of the number of hitting of off-line singing room is proposed and calculated from the log data collected from sampled off-line singing rooms. The difference of online and off-line singing rooms is analyzed and the method of distribution of singing room royalty is suggested.

빅스 바이더벡이라는 트럼펫 연주자는 일반적으로 백인재즈라는 새로운 길을 개척한 인물로 거론된다. 그러나 이 연구에서는 일반론적인 관점에서 벗어나 1920년대 초 흑인 재즈라는 테두리 안에서의 빅스 바이더벡의 독창성이 20세기 초 영문학에서의 새로운 사조였던 ‘의식의 흐름' 이라는 표현법과 그 유사성이 깊은 것으로 본다. 음악과 문학과의 그 흐름상의 유사성을 직접적으로 영향을 서로 어떻게 받았는지를 증명할 수 는 없지만, 표현방법 면에서 볼 때 두 다른 예술 분야에서의 유사성은 충분히 흥미로운 것이다. 특히 미국의 한 재즈연주자의 연주가 같은 시대 영국의 문학에서의 새로운 시도와 그 흐름을 같이 한다면, 현재 우리에게도 다른 분야의 흐름과 음악의 흐름상 연관성에 대한 연구도 보다 폭넓게 이루어 져야 할 것이다.

In this paper, a computer vision system, which catches printed music score image using CCTV camera and microcomputer, and then recognizes the image and performs tar music with speaker, is discussed. Integral projection method is adopted for feature detection and recognition of the music score image. The range of recognition is con(ined to staffs, perpen-dicular lines and musical notes including chord notes among the various kinds of elements of music score. The practical recognition algorithm considering noises, the preprocessing processes getting rid of noises are also showed, and simple hardware system playing chord is made, In the results, good recognition ratio and performance are obtained.

현재 초보적인 능력을 가진 악기 연주자가 접근할 수 있는 하드웨어, 소프트웨어를 사용해 악기 연주법을 연습할 수 있는 수단은 전무하다. 따라서 본 논문은 악기 연주자가 연습을 하기 위해 사용할 수 있는 음 인식과 악보 정보의 처리, LSTM을 통한 자동 악보 생성의 복합적 기능을 가진 악기 보조 시스템을 제안한다. 또한 본 시스템은 기존의 FFT와 같은 일반적인 Pitch Detection 알고리즘보다 더 우월한 음 인식 성능을 보유한 Autocorrelation 전처리를 거친 LeNet-5 Convolutional Neural Network 모델을 사용하여 음 인식 성능을 높이는 기법을 제안한다. 이 음 인식 모델은 실험 결과 기존의 음 인식 기법보다 최대 약 5.4%의 성능 증가를 이루어냈다.

실용음악 산업 분야는 비약적인 기술력의 발전이 있었지만 그런 기술력이 실용음악 교육에 적극적으로 적용되지 않고 있다. 본 논문에서는 음악 산업현장에서 음원 콘텐츠 제작 시 보컬리스트의 음정 보정을 위해 개발된 오토 튠(auto tune) 기술을 활용하여 가창 연주 시 음정과 박자에 관한 실시간 피드백을 시각적으로 학습자에게 제공하는 방식의 학습법을 개발했다.

Recently, playing musical instruments in the application or website which is a sort of playing has been catching on for ordinary people even though they don't know how to play musical instruments. It appears that such playing has randomness which is quite natural. Thus, 'Random operation method' which induces the observing audience and changes them to manage actively is developed and suggested for the image system in this paper by utilizing Launch Pad, based on theoretical background and case analysis. Step Sequencer was developed in two ways: the image system is realized with Step Sequencer by connecting external program or made as clips to arrange them for each key on Launch Pad and implement, which is keyboard launch type.

Understanding is the foundation of music appreciation, the ultimate goal of music learning. The purpose of this research was to create a model for the integration and implementation of Gordon's music learning theory principles into Suzuki violin instruction. This research shows how audiation can be taught within the framework of the Suzuki philosophy and curriculum. It is expected that Gordon's music learning theory can provide Suzuki teachers with unique capabilities for teaching musical understanding, specifically through the development of audiation. Through an audiation-based approach to Suzuki instruction, thus, young violinists will be able to learn to comprehend the tonal and rhythmic aspects of the music they perform. Future researchers may wish to assemble a more complete guide to the tonal and rhythm patterns used in the Suzuki repertoire. Furthermore, additional lesson plans and activities can and should be developed that represent the application of music learning theory to Suzuki violin instruction.

Three classification algorithms are tested using musical instruments. Several classification algorithms are introduced and among them, Bayes rule, NN and k-NN performances evaluated. ZCR, mean, variance and average peak level feature vectors are extracted from instruments sample file and used as data set to classification system. Used musical instruments are Violin, baroque violin and baroque cello. Results of experiment show that the performance of NN algorithm excels other algorithms in musical instruments classification.
