In this paper we propose a serious game for experience of music performance, which allows users to readily enjoy musical playing, even if the player has little or no experience in playing musical instruments. This game makes it easier for users to correctly perform given melodies along with standard performance, using a score-adjusting algorithm that can cope with the particular errors commonly made by beginners. This music performance is achieved by the agent to interpret the gestural sign of the user. We understands the interaction of the user and the agent as a communication model from the Peircean Semiotic perspectives.

The marriage between music and film, both temporal art forms, demands that the inherent aspects of note in each medium are brought into correspondence within a dramatic context. In film-making, the most crucial and difficult problem a film composer faces is finding the music that seems absolutely right for the film and its characters, sequences and dramatic lines. When writing a film score, composers become musical dramatists; some have a special instinct that enables them to find the right kind of melodic line, orchestral texture, rhythmic device and musical style to bring out what they intuitively recognize as the essential aspect of the drama. In this study, several examples are cited - Alex North, Hugo Friedhofer, Bernard Herrmann and David Raksin - that underline this kinetic function of music in film. Effort is made to uncover as many possibilities as possible, so as to arrive at a better understanding of how the two media interrelate for the purpose of emphasizing the dramatic lines.

Mastering a musical instrument for an unskilled beginning learner is not an easy task. It requires playing every note correctly and maintaining the tempo accurately. Any music comes in two forms, a music score and it rendition into an audio music. The proposed method of assisting beginning music players in both aspects employs two popular pattern recognition methods for audio-visual analysis; they are support vector machine (SVM) for music score recognition and hidden Markov model (HMM) for audio music performance tracking. With proper synchronization of the two results, the proposed music learning assistant system can give useful feedback to self-training beginners.

In this research, we seek the beginning of the speech and detect the stationary speech region using lip information. Performing running average of the estimated speech signal in the stationary region, we reduce the effect of musical noise which is inherent to the conventional MlMSE (Minimum Mean Square Error) speech enhancement algorithm. In addition to it, SFM (Spectral Flatness Measure) is incorporated to reduce the speech signal estimation error due to speaking habit and some lacking lip information. The proposed algorithm with Wiener filtering shows the superior performance to the conventional methods according to MOS (Mean Opinion Score) test.

Out of total 39 documents to research musial theory appearing in the introduction of ancient score and anthology in 19th century, ancient scores including introduction were $\ulcorner$GeumboJeongseon(琴譜精選)$\lrcorner$ $\ulcorner$ChilhyeonGeumbo(七絃琴譜)$\lrcorner$ $\ulcorner$HyeongeumOeumTonglon(玄琴五音統論)$\lrcorner$ $\ulcorner$HyeongaGuebeom(絃歌軌範)$\lrcorner$ and $\ulcorner$JukchwiGeumbo(竹醉琴譜)$\lrcorner$ and anthologies were $\ulcorner$GyobangGayo(敎坊歌謠)$\lrcorner$ $\ulcorner$SeungpyeongGok(昇平曲)$\lrcorner$ $\ulcorner$GagokWollyu(歌曲源流)$\lrcorner$ and $\ulcorner$GeumokChongbu(金玉叢部)$\lrcorner$. The results of this study are summarized as followings ; First, the introduction of ancient score reads that musicians should have inherent character and right mind and harmonious sound exerts influence on human being. It emphasized that the proper expression of music is the stabilized mind and right idea. Second, the introduction of anthology lays stress on proper meaning, that is, lyrics that is not indecent nor loose. It asserted that right lyrics should not be pressing nor frivolous, but rather slow. Lastly, the introduction of both ancient score and anthology commonly present 'recovery of ancient music'. It was confirmed that the ultimate purpose of intellectuals and musicians in 19th century was to aim at slow, but harmonious and right music.

Recognition systems for scanned or printed music scores that have been implemented on personal computers have received attention from numerous scientists and have achieved significant results over many years. A modern trend with music scores being captured and played directly on mobile devices has become more interesting to researchers. The limitation of resources and the effects of illumination, distortion, and inclination on input images are still challenges to these recognition systems. In this paper, we introduce a novel approach for recognizing music scores captured by mobile cameras. To reduce the complexity, as well as the computational time of the system, we grouped all of the symbols extracted from music scores into ten main classes. We then applied each major class to SVM to classify the musical symbols separately. The experimental results showed that our proposed method could be applied to real time applications and that its performance is competitive with other methods.

As the computer technology is developed, score-writers that can edit music have more improved functions. A user not only can insert notes, chords, and musical symbols conveniently, but also can listen to music displayed in the score. Existing commercial score-writers make scores look good and play notes through VSTi(Virtual Studio Technology instrument). However chord accompaniment function is so vulnerable that it is hard to know whether or not displayed chords are suitable for music. If a score-writer has a proper function that plays chord sound good to hear, it will be a good reference to band music sheet writers. In this paper, to improve chord playback function in existing score-writers, we propose an algorithm that selects suitable chord tones for chord playback and implemented a program. If we apply this algorithm, the chord play function of a score-writer will be strengthened and resultantly a music sheet writer who makes a band music can make scores more conveniently.

The influence of acquisition environment on music score images captured by a camera has not yet been seriously examined. All existing Optical Music Recognition (OMR) systems attempt to recognize music score images captured by a scanner under ideal conditions. Therefore, when such systems process images under the influence of distortion, different viewpoints or suboptimal illumination effects, the performance, in terms of recognition accuracy and processing time, is unacceptable for deployment in practice. In this paper, a novel, lightweight but effective approach for dealing with the issues caused by camera based music scores is proposed. Based on the staff line information, musical rules, run length code, and projection, all regions of interest are determined. Templates created from inverse filter are then used to recognize the music symbols. Therefore, all fragmentation and deformation problems, as well as missed recognition, can be overcome using the developed method. The system was evaluated on a dataset consisting of real images captured by a smartphone. The achieved recognition rate and processing time were relatively competitive with state of the art works. In addition, the system was designed to be lightweight compared with the other approaches, which mostly adopted machine learning algorithms, to allow further deployment on portable devices with limited computing resources.

Purpose: This study examined the effect of music therapy on the pre-exam anxiety of gastroscopy clients. Method: The research period is from June 17 2002 to August 30 2002, and the subjects were 60 individuals, 30 for the experimental and 30 for the control group among adult clients. The data were analyzed by using the SPSS program. Result: The results of this study were as follows: The score of the experimental group was lower than the score of the control group for the situational anxiety (t=-12.56, p=0.000) and systolic blood pressure (t=-3.97, p=0.000) before the examination was supported. The vital sign was partially supported. There was no significant difference(t=-1.05, p=0.297) in the diastolic blood pressure (t=-1.05, p=0.297) and pulse rate(t=-1.30, p=0.199) before the examination of the experimental group and lower than the score of the control group. Conclusion: Music therapy could be useful in the nursing practice, and be utilized as a way of nursing intervention to reduce anxiety of the patients in specific clinical situations. Finally, it is recommended that further studies be conducted on this therapy by utilizing different musical selections.
