In this paper, we proposed a method for extracting predominant melody of polyphonic music based on harmonic structure. Harmonic structure is an important feature parameter of monophonic signal that has spectral peaks at the integer multiples of its fundamental frequency. We extract all fundamental frequency candidates contained in the polyphonic signal by verifying the required condition of harmonic structure. Then, we combine those harmonic peaks corresponding to each extracted fundamental frequency and assign a rank to each after calculating its harmonic average energy. We run pitch tracking based on the rank of extracted fundamental frequency and continuity of fundamental frequency, and determine the predominant melody. For the query by singing/humming (QbSH) task, we proposed Dynamic Time Warping (DTW) based matching engine. Our system reduces false alarm by combining the distances of multiple DTW processes. To improve the performance, we introduced the asymmetric sense, pitch level compensation, and distance intransitiveness to DTW algorithm.

The goal of this study was to examine the relationship between general creativity and musical creativity of children, and utilize the results as the basic data to develope of children' music education. The subjects were 50 children of a kindergarten located in the Jeonlabukdo area. The instruments employed were general creativity and musical creativity scales. The data were analyzed with the SPSS program. They were analyzed by Pearson Correlation. The results of this study are as follows: First, creativity was correlated positively with 'making of the melody'. Second, fluency was correlated positively with 'making of the melody', abstraction of title was correlated positively with 'making of the song words', and elaboration was correlated positively with making of the melody and expression by rhythmic movement.

This article has reviewed on the characteristics of the Beompae (Buddhist chanting) performed by Gyeongjaeeosan Wonmyeongchang(唱) based on the result of musical style of Gyeongjae Anchaebi-sori as defined under the previous studies. And, through the comparison with the Beompae performed by Songam-chang (唱), a same type of musical piece, it contemplates on musical differences between the two singers. Results of the study are shown as follows. of Gyeongjaeeosan Seolhoeinyu-pyeon and of Socheongsaja-pyeon are sunged as Yuchi-Seong(聲) among Anchaebi-sori. 'main melody type' and 'ending type' are generally similar to the musical characteristics of the Yuchi-Seong(聲), and the differences between the two singers are detected from main melody type D and ending type b. In particular, under of Socheongsaja-pyeon, only the type a is detected among the two types. becouse ending note of ending-type 'a' is ended with 'sol'. The basic frame of the Jjaimsae(musical form) has been clarified in the previous studies that the Jjaimsae of Yuchi-Seong(聲) has been maintained just the way it is. However, even for the same Seong(聲), the combination of the 'main melody type' of passage has not been unified, and depending on the musical piece, it has been discovered that the combination of the 'main melody type' has been diversely organized. of Gyeongjaeeosan Bongsongsajapyeon belongs to Pyeon-gae-seong(聲) broadly from the Anchaebi-sori and it is shown to be So-seong(聲) in details. In particular, in the previous studies, the 'ending melody' of So-seong(聲) and the closing melody of were similar with a slight difference for the 'ending melody'. Such a difference is relation to the characteristics for sequentially descending melody of Wonmyeong-chang(唱). The 'Jjaimsae(The musical structure)' is not much different from the previous studies, and the 'yeok-eum(weaving lyrics)' of Songam-chang(唱) has strong tendency of 3-sobak rhythm while the Wonmyeong-chang (唱) is shown the tendency of 2-sobak rhythm in general for the difference.

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.

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.

While Korean piano pedagogy has seen a remarkable growth, the relatively weak attention to intermediate level has emerged as a pending problem. The limited literature review, specifically the lack of playing Korean original works, has been considered as a serious issue. To emphasize the usefulness of Kim Kukjin's "Pieces of Korean Melody for Piano" as an intermediate work, this study presents practical teaching guidelines by classifying of difficulty in his 25 pieces and providing step by step learning goals and teaching plan. The difficulty stage was based on Jane Magret's 10-step classification table for comparison with other intermediate piano literature, and this study more specifically classified Kim's pieces according to Korean melody, rhythm, and texture. As a result of the difficulty classification, it was found that the pieces from stages 4 to 10 was organized to systematically and comprehensively learn step by step from the most basic progression to Korean 'Jangdan' rhythm patterns, various articulations and decorations that express 'Sigimsae' of Korean Traditional Music, and heterophony texture. In addition, this study proposed the order of pieces for the effective teaching according to the characteristics and difficulty of the pieces. This study suggests that the findings lead to the expansion of Korean intermediate literature study and the revitalization of Korean original works teaching method.

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.
