As the computer technology is developed, score-writers that can edit music have more improved functions. A user not only can insert notes, chords, and musical symbols conveniently, but also can listen to music displayed in the score. Existing commercial score-writers make scores look good and play notes through VSTi(Virtual Studio Technology instrument). However chord accompaniment function is so vulnerable that it is hard to know whether or not displayed chords are suitable for music. If a score-writer has a proper function that plays chord sound good to hear, it will be a good reference to band music sheet writers. In this paper, to improve chord playback function in existing score-writers, we propose an algorithm that selects suitable chord tones for chord playback and implemented a program. If we apply this algorithm, the chord play function of a score-writer will be strengthened and resultantly a music sheet writer who makes a band music can make scores more conveniently.

다양한 문화 활동 중에 음악 활동은 일반인이 가장 접하기 쉬운 영역이다. 이러한 음악 활동을 좀 더 쉽고 체계적으로 해야 할 필요성이 있다. 하지만 악보를 모르는 일반 사용자들은 악보에 대한 일종의 공포심이 있다. 마치 외국어에 대한 트라우마처럼 말이다. 하지만 연습이나 연주 시에는 본인도 모르게 가상의 악보를 따라서 연주를 하는 것이다. 반대로 악보를 보여주면 지레 겁을 먼저 먹기 십상이다. 이러한 사태를 미연 방지하고 나아가서 비전문가들도 자신의 음악을 소유하기 위해서 스마트폰의 어플리케이션을 이용하여 위와 같은 문제를 해소하고 개선하는 것이다.

본 논문에서는 기존 쇼핑몰의 상품 판매 기능을 이용해 음악 관련 컨텐트를 취급할 수 있는 전자상거래 시스템의 개발에 대해 제안하였다. ASP기반으로 동작하며, 일반적인 상품 판매 기능 이외에 악보를 검색, 판매할 수 있는 기능을 추가했다. 악보는 SMF(Standard Midi File)를 소스로 사용해 기존의 인쇄물 흑은 비트맵, 포스트 스크립트 타입의 악보에서는 불가능했던 여러 가지 기능들을 가지며, Music ML을 이용해 악보로 표현하도록 했다. 개발한 시스템을 실제로 사용하기 전에 시뮬레이션을 통해서 검증하였다.

This paper presents techniques to recognize music using back propagation network one of the neural network algorithms, and to preprocess technique for music mage. Music symbols and music notes are segmented by preprocessing such as binarization, slope correction, staff line removing, etc. Segmented music symbols and music notes are recognized by music note recognizing network and non-music note recognizing network. We proved correctness of proposed music recognition algorithm though experiments and analysis with various kind of musics.

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 paper describes an analysis of the music as a time series and the fuzzy logic-based modeling of it. All music is made up of a finite number of musical notations known as the musical symbols, such as clefs, staff, tine signature, notes, rests, etc. . The musical score uses musical symbols to present various characteristics, such as rhythm, melody, chord, etc,. for interpreting the music. In this paper, it is possible to transform the beat and pitch in the musical into time series from the viewpoint of recognizing beat and pitch of sounding tone at each time. On the basis of the identified features of the musical score, a musical score is represented as a time series and then is constructed to fuzzy logic-based model for predicting them. Examples are presented to illustrate the validity of the proposed method.

Traditional indexing mechanism are based on the song's metadata such as the title and the composer and so on. However, these system have a major limitation that users have to know the metadata of the songs they want to retrieve. In order to solve these limitation, we proposed a rhythm extraction system that allows users to retrieve music information efficiently from a large music database using the rhythm that is defined as the parts of the music.

음악에 비유하면 컴퓨터 소프트웨어는 악보에 해당하는 것으로 아무리 악기가 좋아도 악보가 훌륭하지 않으면 아름다운 음악이 흘러 나오지 않는 것과 같다. 소프트웨어는 쇳덩어리인 컴퓨터에 생명력을 불어 넣는 혼과도 같다. 소프트웨어 중에서도 가장 중요한 것이 응용소프트웨어인데 오늘날 우리가 컴퓨터를 유용하게 사용할 수 있는 것도 바로 이 응용소프트웨어 덕분이다.

Music braille is made up of more systematic and various symbols compared with text braille. Therefore, the translation of braille music requires extensive knowledge of the music and the braille symbols. Because currently the computer program for the text braille has already developed, we don't need any help from the braille translator. However, the translation of music braille is hard without the help of a professional music braille translator, because the translation computer program is not perfect. The current situation is that the music braille translator reads the music score and translates it into the braille himself. In this paper, we designed and implemented the "Braille Music Converter", you can implement a person does not understand the braille translation into music braille well. It includes translation into text braille for the lyrics processing and rest, octave, key signature, time signature, tie, slur, repeat mark was confirmed that the successful conversion to the actual music score.

Out of total 39 documents to research musial theory appearing in the introduction of ancient score and anthology in 19th century, ancient scores including introduction were $\ulcorner$GeumboJeongseon(琴譜精選)$\lrcorner$ $\ulcorner$ChilhyeonGeumbo(七絃琴譜)$\lrcorner$ $\ulcorner$HyeongeumOeumTonglon(玄琴五音統論)$\lrcorner$ $\ulcorner$HyeongaGuebeom(絃歌軌範)$\lrcorner$ and $\ulcorner$JukchwiGeumbo(竹醉琴譜)$\lrcorner$ and anthologies were $\ulcorner$GyobangGayo(敎坊歌謠)$\lrcorner$ $\ulcorner$SeungpyeongGok(昇平曲)$\lrcorner$ $\ulcorner$GagokWollyu(歌曲源流)$\lrcorner$ and $\ulcorner$GeumokChongbu(金玉叢部)$\lrcorner$. The results of this study are summarized as followings ; First, the introduction of ancient score reads that musicians should have inherent character and right mind and harmonious sound exerts influence on human being. It emphasized that the proper expression of music is the stabilized mind and right idea. Second, the introduction of anthology lays stress on proper meaning, that is, lyrics that is not indecent nor loose. It asserted that right lyrics should not be pressing nor frivolous, but rather slow. Lastly, the introduction of both ancient score and anthology commonly present 'recovery of ancient music'. It was confirmed that the ultimate purpose of intellectuals and musicians in 19th century was to aim at slow, but harmonious and right music.
