This paper proposes a new method to improve the three problems of existing automatic composition method using artificial neural networks. The first problem is that the existing beat post-processing to fit into music theories could not handle all the cases of occurring. The second one is that the pitch space generated by artificial neural networks is distorted because the rest is trained with the pitch on the same neural network with large values. The last problem is caused by the difference between the initial melody and beats given by user and those generated by an artificial neural network in the process of new composition. In order to treat these problems, we propose an enhanced post-processing of beats, initial melody processing, and adoption of artificial neural network for rest. It was found from experiments that the proposed methods totally resolved the three problems.

This paper introduces a postprocessing method, an iteration method for melody, and an average neural network method for learning a large number of songs in order to improve musically insufficient parts in automatic composition using existing artificial neural network. The melody of songs composed by artificial neural networks is produced according to the melodies of trained songs, so it can not be a specific tonality and it is difficult to have a repetitive composition. In order to solve these problems, we propose a postprocessing method that converts the melody composed by artificial neural networks into a melody having a specific tonality according to music theory and an iteration method for melody by iteratively composing measure divisions of artificial neural networks. In addition, the existing training method of many songs has some disadvantages. To solve this problem, we adopt an average neural network that is made by averaging the weights of artificial neural networks trained each song. From some experiments, it was confirmed that the proposed method solves the existing problems.

The objective of this study is to derive key factors of commentaries in classical music concerts with commentaries and to measure the importance of each attribute, thereby presenting the characteristics of commentaries and commentators as well as suggestions to concert planners in terms of composition. In addition, by developing a scale that can measure classical commentary, a questionnaire is provided so that concert planners can plan programs that gathered the opinions of the audience. To this end, the first, second and third rounds of the Delphi survey and AHP were applied to concert planners, musicians (performing artists), and academic experts. A questionnaire was developed based on the results, and the survey was verified by conducting a pilot test with the general audience. The results of this study can be summarized as follows: First, the purpose of commentaries must be focused on arousing the audience's interest rather than on delivering information. Second, commentators must meet the auditory satisfaction of the audience with a good voice and clear pronunciation based on impeccable vocalization. Third, commentaries must be concise, with the commentaries appearing at least five times per concert, each of which must not exceed five minutes. Fourth, as a result of the pilot test, this study derived 14 items to rate commentary skills across four factors: four items for "arousing interest," three items for "delivering information," three items for "favorability," and four items for "expressiveness." Based on these results, the authors of study presented effective implications for concert planning.

In this paper, we propose a novel technique that generate a new song with given example songs. Our system use k-th order Markov chain of which each state represents notes in a measure. Because we have to consider very high-dimensional space if we use notes in a measure as a state of Markov chain directly, we exploit a hierarchical clustering technique for given example songs to use each cluster as a state. Each given examples can be represented as sequences of cluster ID, and we use them for training data of the Markov chain. The resulting Markov chain effectively gives new song similar to given examples.

The art museum plays a role as a cultural space that can solve the cultural desire of people and see a good art works. It is in exhibition space that they personally exchange the feeling between an art work and a viewer in art museum. The types and works - a fiber, a photo, an establishment that needs many places, devices, a video art, and an action art called "performance", cultural art - are shown in small art museum. Moreover, exhibition spaces are modified into the space of another art activities like dancing, music concerts in small art museum because it has no profit space for diverse art activities. And the exhibition the characters of the exhibition space in small art museum. So, it needs to change the characters of the exhibition space in small art museum. Under these background, this stud\ulcorner surveys and analyzes the exhibits, the organization methods, the modified conditions, and the scale of the existing exhibitional space in small art museum. Therefore, the goal of this study is to suggest the composition of the exhibition space unit considering the function and the multifunction in minimum art museum and small art museum.

음악과 교육은 학생의 잠재력과 창의성을 개발하고, 음악을 통하여 자신의 감정과 생각을 표현하도록 하며, 삶이 질을 높이고 전인적인 인간이 되도록 하는데 그 목적이 있다. 특히, 창작 분야는 자신의 음악적 아이디어를 창출함으로써 자기를 구현하고 자신의 음악성에 대한 자부심을 느끼며 창작의 능력을 향상하는 기회를 제공한다는 점에서 음악의 여러 분야 중 가장 적극적인 음악 체험이라고 할 수 있으나 학교 교육에서는 여러 교육여건의 부재로 인한 어려움으로 가장 소홀히 다루어지고 있는 영역이다. 따라서, 본 연구는 학습자가 창의성 교수-학습에 입각한 세 종류의 단계를 거쳐 음악적 기본개념에 대한 원리 및 기능을 습득하고, 직접 작곡하고 실음을 통해 이를 듣고 수정할 수 있도록 하여 학습자로 하여금 창의력을 보다 향상시킬 수 있는 음악창작학습 시스템을 설계한다.

본 연구는 초등 음악과 창작 학습을 위한 멀티미디어 활용과 그 효과를 알아보기 위하여 멀티미디어 활용 집단과 전통적인 수업 집단으로 구분하여 극용하고 학업성취도를 비교 분석해 보는 것을 목적으로 하였다. 멀티미디어 활용은 Noteworthy 1.70b를 이용하였다. 연구 대상은 부산광역시 장전초등학교 6학년 학생이며, 두 집단으로 구분하여 실시하였다. 연구의 가설로는 멀티미디어 활용 집단의 학업 성취도가 전통 수업 집단의 성취도보다 높을 것이라고 설정하였고, 결과 분석은 SAS(통계분석프로그램)를 사용하였다. 연구 결과 멀티미디어 활용 학습은 학습 집단 전체에 대한 학업 성취도를 균등하게 향상시킬 수 있다는 결론을 내릴 수 있었다.

This study is to look into importance and achievement on awareness of creative musical audiences, who use SNS, by the use of Importance Performance Analysis(IPA), and to find ways to improve the recognition of creative musical by performance enterprise. In other words, the study is to discover choice attributes, that need to be urgently improved, which importance is rated high but which achievement is rated low. As a result, it is learned that composition of content(memorable dialogue), admission fee(ticket prices, charges of using additional facilities), theater(parking), composition of stage(acoustics of the stage), staff services(ticket box staff, usher, and etc. are should be properly controlled by staff expertise) need to be consistently improved. In addition, it is learned for SNS non-user group that choice items such as creative musical choice attribute(admission fee), composition of stage(acoustics of the stage), production(overall music from a musical), admission fee(ticket prices, charges of using additional facilities), and theater(parking) need to be improved.

It seems like many songs have the tonality of one key in jazz standards, but there are many cases in which more than one new key could be formed, despite being a short moment. Moreover, some songs contain keys of temporary changes many times in the event that keys are changed transitionally with the sequencing of cords many times, which is called 'Transitional Modulation with Sequences. The proceeding II-V-I of the major and minor keys are used as the sequencing of cords, and the most popular type in this sequencing pattern is the downward modulation in whole-steps or half-steps. The downward modulation in the interval of whole-steps is a useful technique; for example, there should be three compositions in the adjacency circumstances when it is used twice. We could express effectively a phenomenon that feelings go up to the climax and rapidly fall down. The downward modulation in half-steps must be more dramatic because a higher comparative aspect is made between the adjacent two keys.
