This study was to investigate the effects of percussion program on depression and self-esteem for the elderly lived in residential care. 12 older adults participated in the 40-min. percussion program for 4 weeks(10 sessions). The percussion program consisted of three steps; 1) introduction for creating rapport and relationship, 2) process for mood induction and increasing interaction, and ending for increasing self-achievement and confirming the changed mood. Korean Geriatric Depression Scale (KGDS) and Self-Esteem Scale (SES) were administered before the first session and after the completion of the program. Results showed statistical significance (p<.05) in KGDS (p=.020) and SES (p=.025). Findings imply that percussion program can induce positive changes in depression and self-esteem for elderly in the residential care, and more depressed elderly group may have better outcome in percussion playing. Future studies should consider various levels of depression among elderly, and design the program to be more sensitive to the level of functioning.

In this research, a mono-to-stereo upmixing algorithm based on music source separation is proposed. For the upmixing, a harmonic and percussive separation for jazz music is implemented. Then, the sources are re-panned by equalizing the loudness of left and right sides of listeners in the one proposed approach. In the other approach, the harmonic sources are spread by a decorrelator while the percussive sources are panned to the center. In the experiments, the re-panning algorithm showed advanced performance in terms of localization and timbral quality.

This report shows the new music player's system which could separate music's tempo by analysis Peak level frequency by time from some percussion instruments. After this process, the new music player could classify some fast or slow genre's musics without a user's order, then we should listen to a fast or slow genre's music by a button.

This study investigated the performance patterns in percussion improvisation of adolescents with behavior problems. A total of 40 middle school students participated in this study. Based on prescreening test results, the participants were assigned to either the impulsive tendency or depressive tendency groups. Both groups received two 45-minute group percussion improvisation. During the improvisation, all playing behaviors were recorded and analyzed in terms of rhythm pattern, instrument selection, intensity, and tempo of performance and performance duration. The results showed that while they were differences in improvised rhythm patterns between the two groups, the groups showed a similar tendencies in their instrument selection. With regard to performance parameters, the two groups showed significant difference in the tempo and duration of performance, but no significant difference was found in terms of intensity. This indicates that adolescents who exhibit behavior problems may be different in their playing patterns depending on their behavioral tendencies. Based on the results, music therapists can have a better understanding of how musical features expressed by this population relate to their inherent emotional and behavioral traits and how therapists should facilitate musical expression of these adolescents to address their needs.

현재 국악기의 음향특성에 대한 상세 정보가 매우 부족하며, 이러한 점보의 부재는 국악당의 설계에 있어서 최적의 음향을 전달하는 공간을 형성하지 못하게 하는 한 원인이 되고 있다. 따라서, 대표적인 각종 국악기의 음향특성을 측정하고 분류한 후 데이터베이스를 구축하면, (1) 향후의 국악 및 국악기 개발에 대한 기초연구로서 활용들 수 있으며, (2) 국악전용 연주장의 설계에 있어서 입력 데이터로 요긴하게 활용될 수 있으리라 판단된다. 본 연구는 국악기의 음향방사특성을 조사하기 위한 제 2 단계의 연구로서, 기존의 연구 [1] 에 새로운 국악기 8 종을 추가하였다. 선정된 국악기는 현악기중에서 거문고와 해금, 관악기 중에서 피리와 태평소, 타악기 중 북과 꽹가리, 징 및 남성창으로, 원거리 (far-field) 음향 방사 특성을 조사하였다.

The purpose of this study is to analyze the music of the Moombaton genre and to find out the characteristics of Jamaican music in it. I analyzed Lewis Poncy's and BTS's rhythmically, melodically and instrumentally to find the characteristics of Jamaican music. As a result, the rhythm features a Dembow rhythm and reggae rhythm derived from traditional Jamaican music. and As a feature of the melody, toasting, a unique Jamaican expression method, was used. Instrumental features include Latin American percussion, South American melodic instruments, and the use of tr-808. This study is meaningful in creating another fusion genre by finding the elements of Jamaican music in the current popular genre of EDM.

This paper presents a new method for upmixing mono signal to stereo signal with guaranteeing high stereophonic image quality (SIQ) and large apparent source width (ASW). The proposed method consists of analysis phase and synthesis phase. In analysis phase, a mono signal is first decomposed into multiple sound sources by the use of high-rank nonnegative matrix factorization. Then the multiple sources are clustered into two groups based on tonality criterion. In synthesis phase, one group is directly fed into left and right channels while the other group is decorrelated before being fed into each channel. Subjective tests reveals that the proposed method gives listener high SIQ and large ASW with minimizing timbral distortions.

Since the pre-existing music itself used in has no direct relation to the film, it raises the question of whether it was properly utilized as film music. The purpose of this paper is to clarify that 's 20th century modern music effectively fulfills the role of film music through iconicity with images. This study approached the similarity between the character of fear and the form of music through Hanslick's formal aesthetics to discuss the use of 20th century modern music in the horror film. The formal characteristics of music are observed in the movement of notes, which are similar to the fearful state of mind mentioned by Heidegger. In the analysis, the stagnant movement and the continuity of notes, the special playing method of the musical instrument, the unspecified trembling of the clustered notes, the melody of the weak intensity in the high-pitched range, the smash of percussions, and the progression of the notes that deviate from the center confirms the aptitude of 20th century modern music in the horror film. The fact that this study did not simply rely on the emotions represented in the 20th century modern music, but thoroughly caught the movements of the notes, has great significance in the research of film .

This paper presents the coding method that have multi-mode and efficiency of audio codecs using the feature of audio signal. Recently, the developed extension super-wideband codec based on G.718 wideband divides two mode between Generic and Sinusiodal. So codec efficently encode audio signal exist in super-wideband. But the codec is not as efficent coding for harmonic component of wind instrument and string instrument and individual-Line component of percussion instrument. The proposed method are modeling and encoding multiple pitch and individual-line feature using multi mode coding. For the performance evaluation, we used SNR in MDCT domain for objective test and MUSHRA test for subjective test. As a result, the performance of SNR and MUSHRA test of the proposed method have better performance than the G.718 super-wideband codec.
