In this Paper, we propose a content-based music information retrieval (MIR) system base on the query-by-example (QBE) method. The proposed system is implemented to retrieve queried music from a dataset where 60 music samples were collected for each of the four genres in Classical, Hiphop. Jazz. and Reck. resulting in 240 music files in database. From each query music signal, the system extracts 60 dimensional feature vectors including spectral centroid. rolloff. flux base on STFT and also the LPC. MFCC and Beat information. and retrieves queried music from a trained database set using Euclidean distance measure. In order to choose optimum features from the 60 dimension feature vectors, SFS method is applied to draw 10 dimension optimum features and these are used for the Proposed system. From the experimental result. we can verify the superior performance of the proposed system that provides success rate of 84% in Hit Rate and 0.63 in MRR which means near 10% improvements over the previous methods. Additional experiments regarding system Performance to random query Patterns (or portions) and query lengths have been investigated and a serious instability problem of system Performance is Pointed out.

This study examined the dramatic devices that the production team made for the studio progress in the survival music entertainment program of open narrative structure in which the audience participated through MBC 'The King of Mask Singer'. The reason for the need for dramatic equipment is that the studio Audience who participated in the process of the program crossed the situations of flow, selection, and enjoyment. As a result of the research, the production team of 'The King of Mask Singer' was found to have a device of time margin, lighting and background image, and role of MC in order to change the progress of the studio and that the participating audience naturally change their roles.

Discrimination between speech and music is important in many multimedia applications. Previously we proposed a new parameter for speech/music discrimination, the mean of minimum cepstral distances (MMCD), and it outperformed the conventional parameters. One weakness of it is that its performance depends on range of candidate frames to compute the minimum cepstral distance, which requires the optimal selection of the range experimentally. In this paper, to alleviate the problem, we propose a multi-dimensional MMCD parameter which consists of multiple MMCDs with different ranges of candidate frames. Experimental results show that the multi-dimensional MMCD parameter yields an error rate reduction of 22.5% compared with the optimally chosen one-dimensional MMCD parameter.

With the recent emphasis on evidence-based research and practice, the field of music therapy has called for rigorous reviews of the scientific data and for therapeutic rationales for research procedures. The purpose of this study was to review studies that used a rhythm task as a therapy intervention in terms of whether they provided a rationale for the components related to the intervention. The components included activity rationale, music rationale, intervention validity, intervention format (individual or group), intervention development (contour), duration, and intervention provider. A total of 41 studies were selected: 22 studies were implemented by music therapists and 19 by professionals in other related fields. In terms of seven assessment categories, only 10 studies were found to report more than four items which are related to a rationale of interventions. The 10 studies identified were further examined to determine if their intervention rationale differed depending on whether the study included a researcher-formulated intervention or an existing music therapy protocol. Of the 10 studies, six used a researcher-formulated rhythm intervention, and four used an existing music therapy protocol. Those studies that used an existing music therapy protocol also provided a clear rationale for music selection, whereas those that used a researcher-formulated rhythm task tended to provide an activity rationale. The results of this study suggest that researchers need to be clearer about their interventions and provide an evidence-based rationale for why and how they use a rhythm task.

The aim of this study was to systematically review the latest clinical trials in music medicine and medical music therapy for pediatric patients. Thirteen databases were searched to obtain randomized controlled/crossover design studies published between the year 2000 and 2012 in English language. Out of 1012 articles retrieved in the initial search, fifteen studies were identified based on an exclusion criteria. Overall, selected articles involved children 1 month to 18 years, sample size of 11 to 150, and total participants of 987. Studies were classified and compared as music medicine or music therapy studies through a systematic synthesis assessing general characteristics, methodological quality, measured outcomes, types of interventions and the study results. Seven music medicine and eight music therapy studies measured seven dependent variables using thirty-six different measurement tools with a large heterogeneity in the selection, type, and method of music interventions. Evaluation of the methodological quality revealed that many studies did not provide a full report of the research method, and did not meet some or most methodological standards, such as randomization, allocation concealment, double or partial blinding, and intention to treat analysis. Although overall research results were positive if not significant, poor methodological quality and heterogeneity in design and intervention strategies raise the question of research bias and trustworthiness issues. The systematic review concluded that music may have a valuable clinical effect in addressing the physical and psychosocial needs of hospitalized children, although more rigorous, homogeneous and replicable studies are greatly needed.

20th century music has been recognized as disconnected. Some criticized that it is not music. This controversy has been continued over decades in music history. This study applied Darwin's evolutionary theory to John Cage's 4'33", the most popular music in 20th century and tried to prove musical continuity embedded in it. 4'33" has always been a subject of controversy because it has no sound. However, the study found out that 4'33" has the common musical factor, the rest. 4'33" can be interpreted as the variation of the rest in evolutionary view. The rest has undergone a variety of variations in form and meaning since the beginning of the musical notation and was suitable for a new musical environment changed in 20th century. In the evolutionary view, 4'33" is evolved music, not disconnected.

This study was a literature review to investigate the trends and characteristics of music intervention studies on psychological support for children and adolescents from multicultural families. A total of 19 researches(13 theses and 6 articles) from 2009 to 2018 was reviewed through the selection and exclusion criteria. First, in the general characteristics, researches employing quasi-experimental design and those of one-group pre-post tests scored a higher ratio, and studies for children under the age of 13 also showed the highest percentage. Second, about the intervention characteristics, the goal mainly focussed on self-related factors such as self-identity, self-esteem and self-concept, and with the intervention type, there were mostly found the group activities integrating singing, playing and creating. It is meaningful that this study can be used as basic data developing music intervention programs for them, and suggesting music intervention considering the characteristics of them will be conducted more actively in the future.

The purpose of this study was to examine the effects of music intervention programs for children with ADHD in Korea through systematic review and meta-analysis. For this, nine researches of 1,856 articles published from 2000 to 2019 were reviewed which are experimental studies with the control groups in accordance with selection criteria. As the result of systematic review on four criteria, two or more in each of musical activities, intervention goals, and evaluation tools were employed in most of the nine studies, and there were frequently found studies on sociality and attentiveness. As the result of meta-analysis, there were shown that the overall effect scored medium effect size, and attention deficit and sociality marked low, while problem behavior did medium effect size. It is meaningful that this study showed the importance of using standardized evaluation tools in music intervention for children with ADHD, and it could be used as basic data to develop music intervention programs for them,

The purpose of this study was to review the literature on music interventions with older adults and to analyze the rationale for the type of intervention and type of music selected. A search of KCI journals for research including older adults and music-based interventions identified 33 published articles, and 23 of these studies met the criteria for inclusion in this analysis. Included studies were analyzed in terms of the contents of the interventions and the appropriateness of the rationale reported for selecting the intervention and music. Each study was analyzed in terms of the relevance of the reported rationale to target goals and the characteristics of the study participants. The results showed that many of the included studies incorporated a variety of activities but failed to include a valid rationale for using those activities to achieve the target goals. Also, many of the studies tended to select music based on participants' preferences or perceived familiarity without thorough consideration of the therapeutic function of music in the given intervention. This study presents how music therapy interventions with older adults have been conducted without sufficient attention to the selection of the intervention and presented music. There remains a need to delineate which intervention and music characteristics should be utilized to obtain particular outcomes with specific populations.

This paper proposes an automatic genre classification system for Korean traditional music. The Proposed system accepts and classifies queried input music as one of the six musical genres such as Royal Shrine Music, Classcal Chamber Music, Folk Song, Folk Music, Buddhist Music, Shamanist Music based on music contents. In general, content-based music genre classification consists of two stages - music feature vector extraction and Pattern classification. For feature extraction. the system extracts 58 dimensional feature vectors including spectral centroid, spectral rolloff and spectral flux based on STFT and also the coefficient domain features such as LPC, MFCC, and then these features are further optimized using SFS method. For Pattern or genre classification, k-NN, Gaussian, GMM and SVM algorithms are considered. In addition, the proposed system adopts MFC method to settle down the uncertainty problem of the system performance due to the different query Patterns (or portions). From the experimental results. we verify the successful genre classification performance over $97{\%}$ for both the k-NN and SVM classifier, however SVM classifier provides almost three times faster classification performance than the k-NN.
