Music can give pleasure to people according to a rhythm, and Musical instrument can make various sounds according to quality of the lumber. A string instrument makes sound by strings so it feels very soft and a brass makes to feel a high pitched tone. A gayageum makes sound by oscillation which is transferred to a resonator when a string is touched. And this sound is very soft and faint. Therefore, in this paper, we researched sound properties of gayageum according to quality of the lumber of musical instrument. As the result of researches, we found that melody is affected by the annual ring of the resonance lumber.

As the segmental phonetic output is derived from its underlying form, the phonetic surface of intonation could also be derived from its underlying tone melody. In order to show clearly the phonological processes (in fact, we need more than just phonological processes) involved in the generation of intonational surface, we need to formalize the description of those processes. This paper firstly examines different types of sentence-final intonation contour in Korean, and then attempt to formalize the intonational behavior of those contours. In this attempt, we will investigate what kinds of linguistic information participate in deciding the shapes of the. contours and what kinds of tonological processes the underlying tone melody undergoes before it takes the surface shape. In this analysis of intonation contours, we focus on the linguistic structure rather than the acoustic property, adopting just two tones L and H as phonological tones, with four phonetic pitches.

With the proliferation of digital music, public's interest in music and desire to sing well are increasing. This paper presents the implementation of a tone correction system through a visualization of comparison between music and humming data. For this we extract MIDI note from music and humming data and then design a matching engine using DTW algorithm which is for robust matching results against local timing variation and inaccurate tempo. This system is expected to correct the user's wrong tone by visualization and feedback from the result.

As the smallest unit in the composition of any melody, motive forms the basis for melodic tunes and establishes a starting point for any creation. Among other melody composition methods, how to form a motive, change it, and refine it to develop a solo is important in playing solos, and in an impromptu jazz solo, analyzing how motive is changed and developed and using it can be a method or idea to approach a more melodic solo. This thesis consists of a thorough analysis of the kinds of developmental methods that were used to change and advance motives in three solos by Larry Grenadier, a musician who is active with creative ideas in many genres of contemporary jazz music. After such analysis, these motive development methods were applied to a rendition. Since judgment was used in the motive development methods mentioned in the introduction, elements in the methods that appeared to be motives but were impossible to analyze were excluded from the analysis, therefore making it one limitation of this study. There will be a need for future studies to overcome this limitation.

In this study, we investigated longitudinal music perception of adult cochlear implant (CI) users and how acoustic stimulation with CI affects their music performance. A total of 163 participants' data were analyzed retrospectively. 96 participants were using acoustic stimulation with CI and 67 participants were using electrical stimulation only via CI. The music performance (melody identification, appreciation, and satisfaction) data were collected pre-implantation, 1-year, and 2-year post-implantation. Mixed repeated measures of ANOVA and pairwise analysis adjusted by Tukey were used for the statistics. As result, in both groups, there were significant improvements in melody identification, music appreciation, and music satisfaction at 1-year, and 2-year post-implantation than a pre-implantation, but there was no significant difference between 1 and 2 years in any of the variables. Also, the group of acoustic stimulation with CI showed better perception skill of melody identification than the CI-only group. However, no differences found in music appreciation and satisfaction between the two groups, and possible explanations were discussed. In conclusion, acoustic and/or electrical hearing devices benefit the recipients in music performance over time. Although acoustic stimulation accompanied with electrical stimulation could benefit the recipients in terms of listening skills, those benefits may not extend to the subjective acceptance of music. These results suggest the need for improved sound processing mechanisms and music rehabilitation.

The purpose of this paper is to find out the way of utilizing phrases of Chinese poetry in Manjeongje and its musical characteristics. To this end, the roles of phrases contained in the Pansori words were classified into five patterns: landscape description, strengthening of pleasant emotions, strengthening of sad emotions, wordplay, and combination of various poems. As a result of analysis, phrases quoted in sad mood part consist of slow rhythm of Jinyangjo and Jungmori, and sad melody of Gyemyun-gil and Jingyemyun tone; thus, both the rhythm and melody are expressed in accordance with the mood of poems. On the other hand, the melody in the landscape description parts, and the rhythm in the joyful feeling and wordplay parts showed the characteristics of determining the mood. In addition, when applying the analysis results to the perspective of Pansori composition, it is necessary to discover novel texts, apply to editorials, and study musical implementation suitable for the original mood in order to create more artistic Pansori.

In the field of music, various AI composition methods using machine learning have recently been attempted. However, most of this research has been centered on Western music, and little research has been done on Korean traditional music. Therefore, in this paper, we will create a data set of Korean traditional music, create a melody using three algorithms based on the data set, and compare the results. Three models were selected based on the similarity between language and music, LSTM, Music Transformer and Self Attention. Using each of the three models, a melody generator was modeled and trained to generate melodies. As a result of user evaluation, the Self Attention method showed higher preference than the other methods. Data set is very important in AI composition. For this, a Korean traditional music data set was created, and AI composition was attempted with various algorithms, and this is expected to be helpful in future research on AI composition for Korean traditional music.

Plagiarism concerns in the melody of popular music are on the rise. Despite these concerns, standards and methods for addressing these issues are lacking. This study is significant in the fact that it is the first case in the media which started as a controversy on plagiarism of popular music and even progressed to Supreme Court ruling. The first and second trial courts declared the existence of infringement of copyright by recognizing that the music in question was substantially alike as a result of comparing and reviewing the melody, rhythm, and harmony. However, the Supreme Court came to a different verdict on the infringement of musical work by reversing and remanding the case to the Seoul High Court. The Supreme Court indicated that even though the music presented in the first trial is a creative work entirely protected under the Copyright Act, expression without creativity is an area that is not protected under the law. Based on this case, this study seeks to compare and analyze the essential characteristics of melody in the judgment of infringement of copyrights in popular music, and factors related to the judgment of practical similarity and the judgment of idioms that are the criteria for judging infringement of musical work.

In the past, objective usability was one of the most important aspects when user used system. But nowadays user's subjective experiences are getting more critical element than objective usability in HCI(human-computer interaction). Most people own their mobile phone and use it frequently these days. It is especially important to make user's subjective experiences more positive when using devices like mobile phones people frequently carry and interact with. This study investigates whether the interfaces which express the emotion give more positive experiences to users. Researchers created mobile phone prototypes to compare the effect of mechanical melody feedback(the major auditory feedbacks on mobile phones) and emotional voice feedback(recorded human voice). Participants experienced four kinds of mobile phone prototypes(no feedback, mechanical melody feedback, emotional voice feedback and dual feedback) and evaluated their experienced usability, hedonic quality and preference. The result suggests that person's perceptional fun and hedonic quality were getting increased in the phone which gave the emotional voice feedback than the mechanical melody feedback. Nevertheless, the preference was evaluated lower in the emotional voice feedback condition than the others.
