Thanks to the development of the Internet, people can easily access a vast amount of music. This brings attention to application systems such as a melody-based music search service or music recommendation service. Extracting melodies from music is a crucial process to provide such services. This paper introduces a novel algorithm that can extract melodies from piano music. Since piano can produce polyphonic music, we expect that by studying melody extraction from piano music, we can help extract melodies from general polyphonic music.

Music performance techniques have been primarily trained by apprenticeship. The technique transfer, which relies on the imitation of experience and actual performance without scientific evidence, required the pianists more time and effort than necessary. However, if the players in the field discover the principles of universally applicable piano playing techniques in collaboration with scientists, they will avoid errors and prepare a new paradigm in the development of piano playing techniques. This is why music performance science is needed. Little has been studied about it in Korea, but it has been activated abroad since the mid-1990s. The core science of music performance science is expected to be computer science fitting data analysis. In this paper, we introduce music performance science for the pianist and present how computer can help it.

This study intends to analyze the various spatial structures and characteristics of the museum based on the two of the Renzo Piano's recent projects Menil Collection '||'&'||' Museum and Beyeler Foundation Museum Which defined the direction of the "Third Generation" in museum architecture with reference to the quality of spatial experience and design applications. Comparison and analysis were done on the basic spatial organization floor layout accessibility exhibition area lighting plan and circulation between the two museum. Through the itemized common characteristics of the museum the architect's proposal on meaning and direction of the new museum architecture can be viewed. The contemporary museums distinguish themselves quite clearly from their predecessors and this applies both to their own form and to their spatial organization. As the public demands and requests toward the museum building facility expand everyday the architect must respond by providing multiple types of space where people can experience different atmosphere in each area. One concept he used to create multi experienced area was manipulation of the natural light using by the state-of-the-art techniques of the light filtering system and multi-layering roof system to protect the valuable collections against the direct sunlight. But mainly it was to prove his strong belief in "architecture of light" by creating space with minimized meaning by purposely distinguished area in order to provide maximum support to the physical value of the collection " The connection with nature" is another concept which Piano used to provide the public a tranquil experience through out the architecture which engages in a lively dialogue with art. In spatial organization Piano concerned on functionality which not only concentrated on the visitor's point of view but also on the museum staff's comfort. Unlkie the traditional museum he alternates various size of exhibition areas for spatial hierarchy. Specially the spatial flexibility that the temporary exhibition areas are able to be expanded to the permanent exhibition areas by adjoining t재 spaces differentiate Piano's new museum from the rest. museum from the rest.

Kinect sensors have the ability to recognize the behavior and voice of the user. Due to its low-cost and high accessibility, Kinect sensors have been used in various fields, including healthcare, education and so on. In this paper, we propose to use Kinect in piano education. Specifically, the proposed method first recognizes the coordinate values of user's posture, compares them with coordinate values of teacher's posture and provide real-time feedbacks to the user. This enables user to keep the correct posture even when he is learning piano without a teacher. However, since the piano education is a long process, it is difficult to achieve the correct posture as a teacher immediately. Thus, we propose a user-oriented method to measure the error tolerance rate. The proposed method is the first feedback based piano education system that uses Kinect sensors.

The purpose of this study is to provide methods to improve the teaching of piano technique of intermediate-level learners through the works of Stephen Heller by focusing on rhythm and balance. Although a romantic-era composer, Stephen Heller's works are not well-known. However, when analyzing his compositions, many require the player to focus on their foundational piano techniques and musicality. Heller composed many interesting works including etudes that allow intermediate-level pianists to develop their musicality as much as those playing Chopin or Liszt from the same era. This study presents teaching methods for developing piano technique by focusing on rhythm and balance, and for enhancing musicality to improve the quality and significance of piano education and pedagogical research.

Nitric oxide (NO) has been regarded as one of the neurotransmitters of nonadrenergic, noncholinergic (NANC) nerve stimulation in rabbit corpus cavernosum, rat gastric fundus and human intestine. PIANO (photo-induced adequate nitric oxide) is a very useful tool to investige the role of NO in various smooth muscles where NO is a mediator. The present study was undertaken to compare the physiological responses of the rat gastric smooth muscle in response to NANC nerve stimulation and to PIANO. Photolysis of L-NAME, D-NAME and streptozotocin (572) by UV light in the bathing medium caused relaxation of rat gastric fungus that contracted with carbachol, but was resistant to tetrodotoxin (TTX, 1 $\mu$M). Electrical stimulation (20 V, 2~32 Hz, 0.2 msec, 10s) of the gastric fundus, in the presence of atropine and guanethidine, induced frequency-dependent, TTX-sensitive relaxation. Sodium nitroprusside (1 nM-10 $\mu$M), a NO donor, mimicked the relaxations observed after NANC-stimulation or PIANO. Furthermore, PIANO caused UV light exposure time-dependent increase of CGMP in rat gastric fungus strips. These results provide another evidence indirectly that NO is one of the mediators of the NANC inhibitory nerve stimulation in the rat gastric fundus.

The purpose of this study is to examine the effectiveness of the group piano playing program, which was a part of psycho-emotional support program, on international marriage immigrant women's self-efficacy. For this case study, five international marriage immigrant women from "N Multi-culture Supporting Agency" were agreed to participate in the study. The group piano playing program was implemented for ten sessions. Each session took place once a week for ten weeks. In order to examine the effects of self-efficacy on the participants, both quantitative and qualitative methods were used as a mixed methods research design. As a result, the participants' self-efficacy average score was statistically significant (p< .05). Also, qualitative analysis of participants' verbal and behavioral response showed positive changes in their level of self-efficacy. Therefore, the results of this study suggest that the group piano playing can facilitate as an effective intervention to promote the self-efficacy on international marriage immigrant women.

Germaine Tailleferre is the only woman composer among the French group of six composers known as "Les Six." In her 70-year career, she has left behind numerous chamber music pieces for the piano. Although her chamber music works constitute a significant portion of her overall compositions, research focusing on her piano chamber music pieces is lacking. Therefore, this study introduces a comprehensive list of Tailleferre's chamber music pieces and categorizes each piece according to its performing level of difficulty. Additionally, through a detailed analysis of her <Sonata for Two Pianos>, composed in 1974, this study aims to understand her musical style and artistic world, particularly regarding form, harmony, and melody. <Sonata for Two Pianos>, rooted in the unpretentious and light musical language characteristic of the salon style popular in Parisian cafes and music halls at the time, can be seen as a multi-layered work reflecting various musical languages such as Impressionism, and Neo-classicism. This study may contribute to a better understanding of Tailleferre's musical world and aid in discovering and expanding new literature on 20th-century piano chamber music.

This paper presents a beat gesture recognition method to synchronize the tempo of a robot playing a piano with the desired tempo of the user. To detect an unstructured beat gesture expressed by any part of a body, we apply an optical flow method, and obtain the trajectories of the center of gravity and normalized central moments of moving objects in images. The period of a beat gesture is estimated from the results of the fast Fourier transform. In addition, we also apply a motion control method by which robotic fingers are trained to follow a set of trajectories, Since the ability to track the trajectories influences the sound a piano generates, we adopt an iterative learning control method to reduce the tracking error.
