Although various music composition programs for PCs have become commonplace, the reasons why people think it is hard to make music are the lack of experience with musical instruments, the lack of knowledge of music or composition, and the fear of learning MIDI software. In this paper, we propose an effective method to solve this problem by using plain text based method which makes it easy for the general people who do not know MIDI, have little experience of musical instruments, and cannot even read music to make their own music. As a result, many people who like music but have not been able to produce their own music may produce and distribute music, and collaborate with others to produce better quality music.

With the development of computer music notation programs, when drawing sheet music, it is often drawn using a computer. However, there are still many use of hand-written notations for educational purposes or to quickly draw sheet music such as listening and dictating. In previous studies, OMR focused on recognizing the printed music sheet made by music notation program. the result of handwritten OMR with camera is poor because different people have different writing methods, and lens distortion. In this study, as a pre-processing process for recognizing handwritten music sheet, we propose a method for recognizing a staff using linear regression and a method for recognizing a bar using CNN. F₁ scores of staff recognition and barline detection are 99.09% and 95.48%, respectively. This methodologies are expected to contribute to improving the accuracy of handwriting.

Recently, the globalization of culture and the global trend of K-culture have become a good background for further developing and promoting Korean traditional culture. However, although Korean traditional music has an excellent notation method called Jeongganbo developed by King Sejong, it is gradually not being used as the universality of Western notation. However, since the 7th curriculum, the proportion of introduction and utilization of Jeongganbo in elementary music education has been increasing. And this is a good opportunity to re-generalize our unique traditional notation. On the other hand, in addition to practicing the interpretation of the notation method, more diverse tools will be needed to activate the practice of Jeongganbo. Therefore, this study studied the design of a web program that can make Jeongganbo on the web without installation or download. In addition, in order to increase the user's convenience in the process of publishing Jeongganbo, it designs and proposes a method of inputting using a computer keyboard like a piano keyboard and method of listening to input music information through MIDI function and save it as a file. Through this study, it is possible to develop a web program that anyone can easily and simply approach, practice, and publish, and it is expected to be a useful tool for practicing Korean traditional music or publishing traditional music in the future.

It is the basic direction of revised education course to bring up the autonomous and creative Koreans to lead the 21st century. In the music education of the middle school it could be said that music program using computer is a very effective medium for learners' sake of stimulating their audio-visual sense at the same time. In this study, I will look around the facility of the computer music program and tried to find the application method to connect the creative learning activity in music class. And I will also show the application method in the musical activity area. For this, I proposed the method for students' creative learning activity in the middle of using Finale 2010 for music notation, Window Moviemaker for image editing and Goldwave for sound editing.

PC용 작곡 프로그램의 보편화에도 일반인들이 음악제작을 어려워하는 이유는 악기를 다룬 경험의 부족, 음악 또는 작곡의 지식부족, MIDI 소프트웨어 학습에 대한 두려움 등이다. 본 논문에서는 이러한 문제를 해결하기 위한 기술로 MIDI를 전혀 모르고, 악기를 다룬 경험이 부족하고 또한 악보조차 읽지 못하더라도 음악의 제작 및 작곡, 편곡이 가능한 효과적인 일반 텍스트 기반 음악 표기법을 제안한다. 이를 통해 음악을 좋아하지만 자신의 음악을 제작하지 못했던 많은 일반인들에게 음악을 제작, 보급하는데 큰 도움이 될 뿐 아니라 타인과의 협업을 통해 우수한 품질의 음악을 제작할 수 있다.

This study intends to 1)conform the possibility to transform the enumerated scheme into the faceted scheme, 2)review general theories on facet structure employed in DDC 780, and 3) analyze the facet structure of music. Findings are 1) The facet structure of DDC synthesize the standard subdivisions or specific facet indicators with basic facet. 2) facet indicator 0 is in use to indicate standard subdivision or general principle of music. and facet indicator 1 to general principles and musical forms. DDC has transformed the entire system into the facet structure through its revisions. Especially the music transformed into the facet structure employes the facet indicators and applies them to all the systems in music. But the notation have sometimes twofold meanings, and no ability to differentiate the meanings in the same notation.

In this paper, SA-multiplexed filter is designed using SA (simulated ananealing) to recognize music notation patterns varying in size, shape, position and having considerably many similar shapes for optical pattern recognition system. This filter has correlation resutls at wanted location and can identify same class, classify similar class for scale-varianted or rotation-varianted music notation patterns havng learning process. Also, the optimum filter is oriented to analyze on the similar discrimination at acquired position using SA and enhances optical diffractive efficiency as well as peak beam intensity. Compared with POF *(phase only filter), cosine-BPOF(cosine-binary phase only filter), that has excellent discrimination capability even if the different rate is 0.1% quantitatively.

The purpose of this study is to investigate the problems concerning 780 music division of DDC. The object is especially arrangement of 780 music in the 20th edition of DDC which is the complete revision. The result is summarized as follows : 1. Although music is an important subject in humanities, especially in arts, it was classified as one division (780) not class. 2. The arrangement of 780 music is severely west-oriented music theory, vocal music and instrumental music. 3. Classification number of 780 music becomes longer because of the limitation of decimal notation. 4. 780 music division of DDC neglects music theory and emphasizes music practicing, especially performance. 5. The assignment of classification number is unbalanced, especially between theory and practice, composition and performance, and among sub-sections of vocal and instrumental music. 6. Many important subject are omitted in DDC music schedule, for example, musicology and branches of musicology, composition and traditional instruments of many countries. 7. Employment of terminology is often improper and inconsistant.

Like any other music, Korean traditional music make a beautiful compound melody of many music instruments. In this paper, we separate melody especially played by two instruments, that is Kayakeum, Piri(Korean pipe) analysing each audio signal. Kayakeum, Piri have a unique frequency component for each sound height. Therefore each melody of them can be expressed into each sheet of notation separately and MIDI codes. We expect that this paper will benefit all the people studying and instructing Korean music.

In the past composers used to make music with classical instruments such as piano, violin, guitar, flute, drums, and other well-known tools. With the advent of digital technology many software programs were developed which allow musicians to compose tunes using personal computers. Many file formats were introduced such as NIFF, SMDL and MIDI but none besides MIDI has been successful. Recently MusicXML has emerged as a de-facto standard for the computer representation of music. This paper presents a brief description of the structure of the MusicXML format and describes the development of a music score editor based on MusicXML. We implemented a MusicXML-based score editing software using C# language and a feasibility test showed the efficiency of our proposed method.
