Music summarization means a technique which automatically generates the most importantand representative a part or parts ill music content. The techniques of music summarization have been studied with two categories according to summary characteristics. The first one is that the repeated part is provided as music summary and the second provides the combined segments which consist of segments with different characteristics as music summary in music content In this paper, we propose and evaluate two kinds of music summarization techniques. The algorithm using multi-level vector quantization which provides a repeated part as music summary gives fixed-length music summary is evaluated by overlapping ration between hand-made repeated parts and automatically generated summary. As results, the overlapping ratios of conventional methods are 42.2% and 47.4%, but that of proposed method with fixed-length summary is 67.1%. Optimal length music summary is evaluated by the portion of overlapping between summary and repeated part which is different length according to music content and the result shows that automatically-generated summary expresses more effective part than fixed-length summary with optimal length. The cluster-based algorithm using 2-D similarity matrix and k-means algorithm provides the combined segments as music summary. In order to evaluate this algorithm, we use MOS test consisting of two questions(How many similar segments are in summarized music? How many segments are included in same structure?) and the results show good performance.

In this paper, we present an effective method and a system for the music summarization which automatically extract the chorus portion of a piece of music. A music summary technology is very useful for browsing a song or generating a sample music for an online music service. To develop the solution, conventional automatic music summarization methods use a 2-dimensional similarity matrix, statistical models, or clustering techniques. But our proposed method extracts the music summary by calculating BER(Bit Error Rate) between audio fingerprint blocks which are extracted from a song. But we could directly use an enormous audio fingerprint database which was already saved for a music retrieval solution. This shows the possibility of developing a various of new algorithms and solutions using the audio fingerprint database. In addition, experiments show that the proposed method captures the chorus of a song more effectively than a conventional method.

This paper presents a new methodology for music structure analysis which facilitates rhetoric-based music summarization. Similarity analysis of musical constituents suggests the structure of a musical piece. We can recognize its musical form from the structure. Musical forms have rhetorical characteristics of their on. We have utilized the characteristics for locating musical motifs. Motif extraction is to music summarization what topic sentence extraction is to text summarization. We have evaluated the effectiveness of this methodology through a popular music case study.

본 연구의 목적은 실용음악 전공자와 비전공자 간의 귀벌레 증후군 유발 정도 차이와 음악 차트 순위와의 상관관계를 분석한 것이다. 이를 통해 음악 차트 순위의 이용성을 관찰하는 기초 자료를 제시하고자 했다. 본 연구에 대한 자료를 요약하면 다음과 같다. 첫째, 음악 차트 순위와 귀벌레 증후군 유발 정도 간에는 상관관계가 없는 것으로 나타났다. 둘째, 이와 같은 귀벌레 증후군을 경험하는데 있어서 선율의 반복도, 가사의 반복도, 음원을 접하는 횟수 순으로 영향이 높은 것으로 나타났다. 셋째, 실용음악 전공자의 경우 비전공자보다 귀벌레 증후군을 겪는 빈도가 높지만 그 차이는 미미한 것을 알 수 있었다. 본 연구는 연구결과를 통해 귀벌레 증후군의 유발 정도와 음원 차트 순위는 연관성이 없으나, 음원의 구성 요소와 음원 자체에 노출되는 정도가 많을수록 귀벌레 증후군을 경험할 가능성이 높아지므로, 이러한 두 가지 사실을 통하여 음악의 차트 상의 순위가 높은 정도와 대중들이 그 음악을 접하게 되는 정도가 동일하지 않을 수도 있다는 시사점을 제시하였다.

The present paper describes the effects on human body by music and vibroacoustic stimuli. The experiments were carried out six times for 3 subjects and have investigated the electroencephalogram of all subjects against six music stimulus having vibration or non-vibration. From the experimental results, we can distinguish which musics were useful for a relexation and a reduction of stress or effective for power of concentration. We made sure that the music and the vibroacoustic stimuli have been the more effective and the more sensitive than the only music stimuli. And the close investigation and examination to the effect of acoustic vibrations will be applied for healing of a disease and so on.

This study is an analysis and review of the international research on interventions using music for the rehabilitation of patients with Parkinson's disease(PD). It categorizes 24 intervention studies conducted over the last 20 years based on the level of music usage and type of music utilized. The aim of this analysis was to identify which musical elements improved timing issues related to the initiation and cessation of movement in patients with PD. The studies involved six with music-based interventions and 18 with rhythm-based interventions, depending on the level of music usage. Rhythm, a common element in music, was a suitable factor for addressing the participants' issues. Furthermore, this review suggests that the characteristics of the researchers impact the extent to which musical elements are used and the diversity of those elements, which influences the intervention's effectiveness. Therefore, this study provides information on how to specify and systematically consider intervention efforts and the use of musical elements that can be applied in rehabilitation for patients with PD.

This study analysed the effect of music tempo on young drivers' driving speed. 23 male college students under age 26 were randomly assigned to one of three music conditions as follows; No Music, Slow Music and Fast Music. Every subject's travel time(sec) and driving speed(Km/h) was recorded while they were driving a computer-based driving simulator. As the results of this study, we found that 1) the fast music group's mean of travel time was the shortest and also, 2) their mean of driving speed was the fastest. The effect of music tempo on driving speed can be explained as a biological mechanism, same as the effect on our heart-beat rate or intensity of physical exercising. This result shows us that listening musics while driving can affect the driving speed instead of the driver's physical condition.

In this paper, an automatic construction method of theme melody index for large music database and an associative content-based music retrieval mechanism in which the constructed theme melody index is mainly used to improve the users' response time are proposed. First, the system automatically extracted the theme melody from a music file by the graphical clustering algorithm based on the similarities between motifs of the music. To place an extracted theme melody into the metric space of M-tree, we chose the average length variation and the average pitch variation of the theme melody as the major features. Moreover, we added the pitch signature and length signature which summarize the pitch variation pattern and the length variation pattern of a theme melody, respectively, to increase the precision of retrieval results. We also proposed the associative content-based music retrieval mechanism in which the k-nearest neighborhood searching and the range searching algorithms of M-tree are used to select the similar melodies to user's query melody from the theme melody index. To improve the users' satisfaction, the proposed retrieval mechanism includes ranking and user's relevance feedback functions. Also, we implemented the proposed mechanisms as the essential components of content-based music retrieval systems to verify the usefulness.

177-Existing music recommendation systems do not sufficiently consider the discrepancy between the intended emotions conveyed by song lyrics and the actual emotions felt by users. In this study, we generate topic vectors for lyrics and user comments using the LDA model, and construct a user preference model by combining user behavior trajectories reflecting time decay effects and playback frequency, along with statistical characteristics. Empirical analysis shows that our proposed model recommends music with higher accuracy compared to existing models that rely solely on lyrics. This research presents a novel methodology for improving personalized music recommendation systems by integrating emotion recognition and user behavior analysis.

This study looks into the relationship between Chinese philosophy, with a focus on Confucianism and Taoism, and music. Kong zi's Confucius supported, 'Enjoyment without being licentious and grief without being hurtfully excessive', and 'hatred of the music of Zheng'. These ideas do not emphasize the function of music as an expression of emotions, feelings, or desires, and are instead conclusions based on Confucian ideals such as harmony between classes and the spread of benevolent government. Music must coincide with Justice. The hatred of the music of Zheng was a conclusion founded on the idea of a place for Justice in music. Zhuangzi is the source of the spirit of Chinese art; specifically, Zhuangzi's idea of music in relation to its influence on East Asian history of art is extremely influential. In fact, the concept of yuelun is considered the most original and important concept in the history of the East Asian philosophy of art. The most distinctive features of Zhuangzi's theory of music can be summarized as follows. He attempts to liberate music from the restrictions of form and to let music express authentic human feelings and emotions. He also argues that music should not be subjected to politics, as he thinks that the creative mind of an artist can exist only when music is freed from political influence. Confucianism takes a humanistic perspective, while Taoism takes a more naturalistic one. In sum, Confucianism gives weight to the logical and ethical aspects of music, while Taoism emphasizes the intuitional and naturalistic ones.
