A unified method for separating musical sources, singing voice for example, from stereophonic mixtures is provided. We usually have two observed signals in stereophonic music contents, where more than two instruments are played together. If we regard each instrument as source, this problem becomes an underdetermined source separation problem and cannot be solved by conventional methods, which infers the spatial environment of the downmixing process happens. Instead, source-specific information has been exploited to recover a particular instrumental source. This paper provides a unifying structure consists of heterogenious ad-hoc separate algorithms, which are designed for separating vocal sources using stereophonic channel information and dominant pitch information of the sources, respectively. Experiments on real world music contents show that the proposed unification can neutralize the drawbacks of the two ad-hoc separation algorithms and finally enhance the separation results.

본 논문에서는 피아노 음으로 구성된 간단한 웨이브 (Wave) 형식의 연주곡으로부터 각 음들의 음높이인 피치(pitch)를 추출하는 방법과 연주곡의 악보를 생성하는 방법에 대해 연구한다. 본 연구의 최종 목적은 위의 방법을 사용하여 클래식 악기로 연주된 CD-DA방식의 음악을 같은 음질이 보장되는 MIDI [1,3,7,8] 데이터로 변환하는데 있다. 이번 연구에서는 하나의 악기(피아노)로 연주된 음악으로 고정시줬으며, 잡음이 없는 깨끗한 웨이브 사운드로 제한하였다. 웨이브 사운드 형식으로 된 간단한 피아노 연주곡을 입력 데이타로 사용하였다. 이 웨이브사운드에서 Autocorrelation[4,5,6]방법을 사용하여 각 음들의 피치를 추출하였다 또한, 웨이브 사운드로부터 추출한 음의 피치, 음의 지속시간 등의 정보를 사용하여 연주곡에 대한 악보를 생성하는 방법에 대해 연구하였다. 본 논문에서는 웨이브 사운드 데이터에서 악보로의 변환까지를 이루고 있지만, 향후 실제 클래식 악기와 흡사한 MIDI 음원모듈이 제공될 경우 CD-DA방식의 원음과 같은 음질의 MIDI 음악을 생성하는 것도 가능할 것이다.

This study aimed at examining the music world of the composer Muczynski, who played an important and meaningful role in the various experimental trends of music which began to appear in the early $20^{th}$ century, and his works, thereby understanding his relationship with the development of music of various genres today. In the study, his pieces of piano music among his works, which formed the basis for his music, were analyzed. The study examined stylistic characteristics, that is techniques of various types including form, melody, harmony, tonality, rhythm and structure, and introduced the composer's growth in terms of music and philosophical background. Muczynski, the composer who showed the characteristics of neoclassicism, neoromanticism and neobaroque in contrast to the various forms of the $20^{th}$ music, namely music of free styles including atonal music, twelve-tone technique, avant-garde music and electronic music, used traditional forms. However, the characteristics of his works are very free. In addition, in the 1960s, he participated in the production of documentary movie music, creating very creative and sensational music. Muczynski's music has the features of tonality and shows neoclassic and neoromantic features including economical idea, lyrical melody, bitonality and nine-note scale. His music, therefore, is being evaluated as very creative and valuable and is largely significant in that it has provided a good basis for the development of modern movie music and jazz music today.

Since genre of popular music began to classified, Alternative Music has been music form with most complex and diverse sub genre. This paper focused on mostly Alternative Rock, which began to attract attention since the 1990's, and analysed the cause for ambiguity of this genre. Therefore we can examine the inevitable limitation of traditional - based on musical form only - classification.

Thanks to the development of the Internet, people can easily access a vast amount of music. This brings attention to application systems such as a melody-based music search service or music recommendation service. Extracting melodies from music is a crucial process to provide such services. This paper introduces a novel algorithm that can extract melodies from piano music. Since piano can produce polyphonic music, we expect that by studying melody extraction from piano music, we can help extract melodies from general polyphonic music.

This study is to present a draft for the formulation of uniform title for sound recordings of the Korean traditional music. The draft as the results of this study is summarized as follows: In a musical work of a type of non-composition, the popular name is put into square brackets as a uniform title of court music and folk music in the old Korean traditional music, and the composer's original title is put into square brackets as a uniform title of the new Korean traditional music, but the medium of performance and others are omitted except an identifying element. However, for the formulation of uniform title of a type of composition in an instrumental music, the descriptive form consisted of the order of 'name of one type of composition, medium of performance, serial number, opus number, key, and a descriptive word or phrase' is put into square brackets as a uniform title and the identifying elements. And in the vocal music of the old Korean traditional music, the following medium of performance is used: in vocal choruses, a type of voices; in solo voices, a type of solo voice by sex, but one of the new Korean traditional music follows the descriptive form of the western classical music.

본 논문은 멀티미디어의 특성을 활용하여 초등학교 5학년의 음악과 전 영역을 멀티미디어 CAI로 설계하고 구현함으로써 음악에 대한 기초개념과 악곡에 대한 이해와 관심을높이고 학습자에 대한 개별학습과 교수-학습의 효율성을 높이고자 하였다. 이에 따라서 멀티미디어 CAI에 관한 이론을 탐색하고 CAI의 설계원리 및 교과의 특성을 고려하여 Hannafin와 Peck이 제안한 코스웨어 설계모형을 모델로 하였다. 설계모델에 따라 교육과정을 분석하여 멀티미디어 적용요소를 추출하였으며 저작환경에 적합한 스토리보드 형식을 작성하였다. CAI 코스웨어 설계모형에 준거하여 객체지향적이고 상호대화적인 접근을 가능하도록 멀티미디어 디렉터를 도구로 사용하였다. 본 CAI 프로그램은 멀티미디어(Text, Image, Graphic, animation, sound)를 활용하여 주의집중과 동기유발을 높혔고 특히 가창, 기악, 창작, 감상, 이론적 내용, 형성평가의 모든 음악적 영역을 교육과정의 내용에 일치시켜 충실한 교수-학습이 이루어지게 하여 모든 교사의 현장수업에 대한 부담감을 감소시켰다.

Capcom released Street Fighter 5 Arcade Edition on January 17, 2018. It also launched STREET FIGHTER 30th ANNIVERSARY COLLECTION. This product is a compilation of 12 of the Street Fighter series. The Street Fighter series was refocus by this work. In terms of game musical, Street Fighter IV and Street Fighter V almost used the Street Fighter II's melody. This means that the theme music of each character of Street Fighter 2 has a great influence on the sequel. Therefore, it is expected that analyzing the theme music of the original Street Fighter II will inspire game music composers. As a result of studying series of Street Fighter, the difference of form and genre was remarkable.

Mentally disable children feel as failure because they have difficulty in restricted and undifferentiated communications with others. It also makes the counter-partner feel frustrated. Therefore, in the aspects of language acquirement and communication activities, it is essential to let the disable children learn and communicate voluntarily. Music provides the unthreatening and interesting stimulus as non-language communication vehicle. Musical experiences for mentally disable children's are multi-stimulating experiences that make a positive influence in speech and language development and development of variety of talents. There are many communication intervention and method to treat the mentally disable children. One of the most effective treatments for mentally disable children to acquire communication techniques by expressing the language more naturally and joyfully is the musical therapy. This study analyzes children's communication technique referring to response action and attempt action through video tape observation. Also, this study measured the receptive and expressive language by PRES(Preschool Receptive-Expressive Language Scale) as a test tool in order to examine the pre-post language ability for respective children as pre-post period of therapy activity. First result of this study showed that music therapy with song was effective for mentally disable children in enhancing the communication techniques centered with communication response and in attempt action by increasing the communication action incidence. Secondly, pre-post comparison test with PRES showed that the music therapy with song was effective on improvement the receptive and expressive language ability of 4 children.
