The purpose of this study was to investigate the effect of vocal and instrumental background music on a verbal memorizing task. Participants were 30 undergraduate and graduate students and were randomly divided into two groups. All participants in both groups took a pretest and a posttest to examine the improvement of the memorization. Background music was inserted during the memorization task. Subjects in Group A listened to a vocal recording whereas Group B listened to the same music except with a cello playing the melody of the vocal part. All participants were asked to take the posttest to examine the improvement of their knowledge after the memorization. The t-test was used to compare the two groups. Results indicated that Group A(8.93) exhibited higher mean scores than Group B(7.46) but there were no significant differences t(28) = 1.38, p < .05. This study implies that lyrics does not distract word memorization and background music does not influence cognition directly.

This studied investigated children's music identification, classification, and seriation cognitive task performance abilities by age and sex. The subjects were l20 six-, eight-, and ten-year-old school children. There were significant positive correlations among music cognition tasks and significant age and sex differences within each of the music tasks. Ten-year-old children were more likely to complete their music identification tasks than the younger children and girls were more likely than boys to complete their music identification tasks. Eight- and 10-year-old children were more likely to complete their music classification tasks than the younger group. Piagetian stage theory was demonstrated in children's music classification task performance. There was an age-related increase in the performance of the music seriation tasks. Developmental sequential theory was demonstrated in music seriation performance.

We suggest a graphical representation of the tension flow in tonal music using a piecewise parametric curve, which is a function of time illustrating the changing degree of tension in a corresponding chord progression. The tension curve can be edited by using conventional curve editing techniques to reharmonize the original music with reflecting the user's demand to control the tension of music. We introduce three different methods to measure the tension of a chord in terms of a specific key, which can be used to represent the tension of the chord numerically. Then, by interpolating the series of numerical tension values, a tension curve is constructed. In this paper, we show the tension curve editing method can be effectively used in several interesting applications: enhancing or weakening the overall feeling of tension in a whole song, the local control of tension in a specific region of music, the progressive transition of tension flow from source to target chord progressions, and natural connection of two songs with maintaining the smoothness of the tension flow. Our work shows the possibility of controlling the perceptual factor (tension) in music by using numerical methods. Most of the computations used in this paper are not expensive so they can be calculated in real time. We think that an interesting application of our method is an interactive modification of tension in background music according to the user's emotion or current scenario in the interactive environments such as games.

This study examined the effects of a tablet PC-based music-making program on the executive function of adolescents with intellectual disabilities. Four adolescents with intellectual disabilities participated in this program. Each participant received 45-minute individual sessions twice a week for a total of 16 sessions. The music-making program was designed in the sequence of planning; learning table PC operations; exploring musical elements; making rhythm, melody, and lyrics; composing loop sections; and presentation of the completed music. The Stroop test, Children's Color Trails Test, and Digit Span and Letter-Number sequencing tests were measured at pretest, midtest, and posttest in order to examine changes in executive function. The participants showed increased scores on all three tests. The participants' attention span also increased and their attempts to correct errors during tasks occurred more frequently at posttest. This study supports the effects of the technology-based program on the executive function of adolescents with intellectual disabilities and presents its expanded applicability for adolescents who show low cognitive function and limited motivation for cognitive engagement.

Music plays significant roles in the process of human development. The requirement in each process of development can be encouraged by children's participating in various musical activity and so the musical circumstance can make an important factor. Acknowledging that, there were some attempts to use music as a means of treatment or education for children. The subjects of clinic studies in music therapy, especially in Korea, have mainly been children with delay or disability in development. The purpose of this article is focused on collecting and analyzing articles which are written about children who are the main subjects of clinic studies. By collecting and analyzing those articles, the tendency of domestic studies about music therapy concerned with children can be widely examined. Ninety thesis about music therapy related with normal and disabled children have been collected and analyzed considering the subjects, methods, fields of the studies and musical intervention. The conclusions are the same with followings. First, considering the subjects, the studies on children with disabilities are more than normal children and the studies on autistic children occupy the largest portion of them Recently the studies on normal children have been increased as well as the studies on children with disability. Second, for the methods1 experimental studies have been performed more widely than descriptive studies. Third, considering the fields of development, the studies on the social field occupies the largest part of all and they are followed by emotion, language and communication, cognition in turn. Last, in case of musical intervention, it is clear that musical intervention is more used as forms of singing songs and playing instruments than special skills of music. Through this article, the achievements and shortcomings in this territory could be possibly shown at the same time. Moreover, the direction which it has to move toward could be shown.

The purpose of this study is to analysis the cognitive frame of the expert on musically talented in the Pop music audition program. Consequently, this article found that each expert has difference priority. Myself(PA), voice(YA), tune(YO) are used frequently. In comparison with standard frame, all experts refer to creative area in priority. But, they lack in motive area. Also, there are areas which don't treat in standard frame. And to conclude, pop music audition program has creative and personal characteristic. If not, it doesn't give prominence to differentiated messages and last in the global market. Based on the result of this study, this paper suggests the following: Firstly, it needs devices that support areas which fall short of selection. Secondly, it requires new frame which modifies the details of standard frame.

The roots of modern popular music have evolved from blues and jazz music. But now, due to various multimedia developments and the expansion of the online industry, these traditional music is gradually being shunned by the public. When measuring a nation's cultural scale, it does not value only a few genres of popular music. In many advanced countries, music, which has basic artistic value, is trying to support and grow more base expansion in government and businesses, and to meet the needs of consumers. At this time, local jazz and jazz clubs are gradually losing ground, out of dance, rock and ballad music. Everyone should recognize that it is not just a genre of music that is alienated from the trend of the times, but an important part of cultural art that we should develop and nurture systematically. And it should be handled by more media and recognized by the public. Although it is a small market, this paper analyzes the development of jazz music in Korea and various factors that jazz clubs can establish as part of the music industry through analysis of Korean jazz clubs. The artistry and popularity of jazz music, the development of music education programs, the revitalization of government-led performances and the operation of concert halls differentiated from those of broadcasting media will eventually lead to the development of jazz clubs due to the rise of many jazz music lovers. It is also hoped that through the direction of development, we will be able to succeed as a major part of pop culture.

Movement is everything in life and music is with our whole lives. Based on movement and sound, art has developed and reflected the times with close ties to technology and is creating new cultural content in the digital age. The absence of experts and research institutes with academic knowledge and experience in various fields compared to the frequency with which music and body movements are interwoven in the intermedia art and education of convergence is a real problem. Introducing the Rhythmik that studied the most basic principles of music and exercise through the precedent of foreign universities, we raise the need to introduce music physiology, musicians' Medicine and music performance science, the areas we studied together. It presents a new direction in the convergence era and education in pioneering research areas in which the only "I myself" systematically recognizes the movement to become the subject through physiology and medicine and scientifically moves and expresses music as a medium.

Recently, in content-based music information retrieval systems, to enhance the response time of retrieving music data from large music database, some researches have adopted the indexing mechanism that extracts and indexes the representative melodies. The representative melody of music data must stand for the music itself and have strong possibility to use as users' input queries. However, since the previous researches have not considered the musical composition forms, they are not able to correctly catch the contrast, repetition and variation of motif in musical forms. In this paper, we use an index automatically constructed from representative melodies such like first melody, climax melodies and similarly repeated theme melodies. At first, we expand the clustering algorithm in order to extract similarly repeated theme melodies based on the musical composition forms. If the first melody and climax melodies are not included into the representative melodies of music by the clustering algorithm, we add them into representative melodies. We implemented a prototype system and did experiments on comparison the representative melody index with other melody indexes. Since, we are able to construct the representative melody index with the lower storage by 34％ than whole melody index, the response time can be decreased. Also, since we include first melody and climax melody which have the strong possibility to use as users' input query into representative melodies, we are able to get the more correct results against the various users' input queries than theme melody index with the cost of storage overhead of 20％.

This study examined the correlation between the rhythm reproduction performance and cognitive function of school-aged children. A total of 59 third grade elementary students participated in this study. An iPad-based rhythm reproduction task, the Digit Span Test (DST), the Children's Color Trails Test (CCTT), and a self-paced tapping task via a MIDI keyboard were conducted for each participant. The results demonstrated that scores at each stage of the iPad-based rhythm reproduction test showed different patterns of correlation with cognitive function test scores. This result suggests that accuracy of a simple rhythm task is correlated to speed of self-paced tapping (second). Also cognitive function may affect rhythm grouping ability. Results of this analysis for each of 20 rhythm items showed that there was a common rhythm characteristics that correlated with executive function, working memory or self-paced tapping speed. These results indicate that rhythm ability is related to, and predictive of, the level of cognitive functioning in elementary school students and can be used as an useful parameter when examining cognitive function of school-aged children in multifaceted dimensions.
