  • This paper, which is about the method of creating the audio fingerprint and comparing with the audio data, presents how to distinguish music using the characteristics of audio data. It is a process of applying the Difference of Gaussian (DoG: generally used for recognizing images) to the audio data, and to extract the music that changes radically, and to define the location of fingerprint. This fingerprint is made insensitive to the changes of sound, and is possible to extract the same location of original fingerprint with just a portion of music data. By reducing the data and calculation of fingerprint, this system indicates more efficiency than the pre-system which uses pre-frequency domain. Adopting this, it is possible to indicate the copyrighted music distributed in internet, or meta information of music to users.

  • 판소리의 특질을 연구하기 위하여 여덟 명창의 소리를 분석하였다. 그 결과 모두에게서 유성음임에도 불구하고 비주기성인 소리를 찾았다. 이러한 현상은 매우 높은 성대밑 공기압에 기인한다고 보았다. 이 비주기성 유성음은 명창들의 일반 대화에서도 나타나서 이러한 현상이 곧 성대의 영구적인 변화에 의한 것임을 추정할 수 있었다. 또한 판소리에서 나타나는 vibrato는 서양의 오페라에 비해 주기가 훨씬 길고 범위는 훨씬 넓음이 확인되었다. 그 외에도 모든 명창의 경우 고주파수 영역에서 매우 높은 에너지를 보여주어서 일반인의 발성과 차이가 남을 알 수 있었고, 특히 일부 명창의 경우는 1000Hz 바로 이하에서 유별나게 강한 harmonics가 나타나서 서양 음악의 소위 singer's formant와 대조를 이루었다.

  • The role of bass in band or ensemble music literally sets up the foundation of harmony, which must be regarded first. On the other hand, this is also considered so basic or stable that it can be slightly boring to the listeners. Consideration is needed to make the varied trials more exciting. In this sense, Rutger Gunnarsson showed these fine examples not in performing music but in pop music through the Great ABBA. He could make a fabulous sound with only a basic performance, not with a florid technique or rhetorical skills. All bassists must bear in mind that the overall performance depends on the bass. In short, to make better music, remember to practice continually and find better methods.

  • This paper proposes a rapid detection algorithm of a salient region for music video browsing system, which can be applied to mobile device and digital video recorder (DVR). The input music video is decomposed into the music and video tracks. For the music track, the music highlight including musical chorus is detected based on structure analysis using energy-based peak position detection. Using the emotional models generated by SVM-AdaBoost learning algorithm, the music signal of the music videos is classified into one of the predefined emotional classes of the music automatically. For the video track, the face scene including the singer or actor/actress is detected based on a boosted cascade of simple features. Finally, the salient region is generated based on the alignment of boundaries of the music highlight and the visual face scene. First, the users select their favorite music videos from various music videos in the mobile devices or DVR with the information of a music video's emotion and thereafter they can browse the salient region with a length of 30-seconds using the proposed algorithm quickly. A mean opinion score (MOS) test with a database of 200 music videos is conducted to compare the detected salient region with the predefined manual part. The MOS test results show that the detected salient region using the proposed method performed much better than the predefined manual part without audiovisual processing.

  • Online education is a new domain of learning that combines distance learning with the practice of face-to-face instruction utilizing computer-mediated communication. As technology continues to develop and the needs of teachers require better access to higher learning, online graduate degree programs can be a valid alternative. Some institutions in the United States have already offered graduate degrees in music education through the online distance learning. In this study, 8 accredited online graduate degree programs in music education were identified in terms of curriculum requirement, program requirement, and admission requirement. Online programs offer considerable benefits of convenience, while their drawbacks relates to the quality of learning, feelings of weaker interpersonal interaction. More researches need in order for online music programmers to achieve higher standards of instruction and to inform other disciplines in the fields of arts education and the performing arts.

  • Drum Set are representative instruments that use grips in modern popular music. Depending on how and how clearly you hold the basic grip, it also affects your performance ability. The purpose of this study is to analyze the characteristics, strengths, and weaknesses of each grip, derive the resulting complex effects, and present practical application plans to the drummers. The research method is largely divided into traditional and matched grips, and in detail, German, American, French, and hybrid styles are included to analyze the performance method utilized. It also refers to the grip method of all drummers from the 1930s to the present, which was registered in Drummer World, an overseas drum site. This study proposed several application plans by classifying and analyzing the most basic grip methods in drum set in detail. I was able to see that the performance impact was different depending on the grip, and I think it will be more helpful for future performances if I understand both the positive and adverse functions of each grip and play it.

  • The purpose of this study is to explore the formal and content features of the material for the Changgeuk album , which was produced and released in 1971. Changgeuk album was produced and published as a headword for "Changgeuk". However, it differs from the style of Changgeuk which is treated as a stage drama in that the narrative is developed around the commentary and dialogue in the formal aspect and the Pansori is only partially used. The styles of Changgeuk, implemented through gramophone record, radio broadcasts and television broadcasts, varied widely, unlike those of Changgeuk established in the 1930s. Pansori music wasn't the only center, and traditional performers weren't even the main members of the play. The characteristic form of the Changgeuk album is an experiment of Changgeuk that emerged naturally with radio reading and the advent of radio dramas in the 1950s and 1960s. So it is necessary to pay attention to the Changgeuk album in that it shows diverse forms of experiments conducted by Changgeuk in the newly introduced culture and media in the middle and late 20th century As for the contents of the Changgeuk album , the work embraces Lee Jong ik 's novel (1957), but develops the narrative centering on the life of Saint Sa-myung(四溟大師). And it is faithfully portraying the life of a Buddhist monk and the national salvation hero who pursued the original work. This content composition can be understood in the will of singer Lee Yong bae, the soundman who produced the album, and in the flow of historical dramas that summon the historical hero of the old country of the time to the stage. Singer Lee Yong bae reflects on his life in the past when he was full of greed and conceit through his life as a monk of Saint Sa-myung(四溟大師) and is greatly impressed by the personal aspect of Saint Sa-myung(四溟大師), and these emotions encouraged his creative will. Also, the Changgeuk record is meaningful in that it is one of the specific materials that embodies the national hero as a record and a traditional play under the discourse of the people, the nation in the 1970s.

  • The music videos of and were made based on the music of Pink Floyd and Beatles. This study aims to compare the characteristics of the two songs in terms of music and storytelling method. Previous studies investigated the narrative structure and concept of the storytelling, which are the basis of the images. This study, a comparative study of the two songs, firstly analyzed the narrative structure focusing on the roles and relationships among characters in each song. Secondly, it investigated the method of composition structure and the characteristics of the two pieces of music of which genre is different from each other. Thirdly, it classified the images into intro part, development part, and conclusion part and analyzed by comparison how the song or images inserted in the music interacts with each other. As a result, it was found that described strong progressive rock from the subjective viewpoint through the material storytelling structure by space and it represents the alienation of the hero through simile and metaphor, spatial changes crossing the past and the present, and the actual and non-actual crossover directing. On the other hand, developed a narrative storytelling structure in which progressive fantasy images developed from the psychedelic viewpoint through the confrontation of the good and the bad to deliver the messages of love and peace.
