  • Nanotechnology has emerged as a promising avenue for enhancing musical structures. In this study, we analyze the static behavior of laser harp (i.e., electronic musical instrument) reinforced with Zinc Oxide (ZnO) nanoparticles. Leveraging the piezoelectric properties of ZnO nanoparticles, the structure is subjected to an electric field for intelligent control. The electronic musical structure is situated in a foundation with vertical springs and shear modulus constants. We employ the exponential Shear Deformation Beam Theory (ESDBT) to mathematically model the structure. A micro-electro-mechanical model is employed to determine the equivalent properties of the system. By utilizing nonlinear stress-strain relations, energy methods, and Hamilton's principle, we derive the motion equations. The buckling load of the electronic musical beam is calculated using the Difference Quadrature Method (DQM). The primary objective of this study is to present a mathematical model for electronic musical beams and determining the buckling load of the structure and to investigate the influence of nanotechnology and electric fields on its buckling behavior. The buckling is the case when the structure becomes deforms and unstable. Our findings reveal that the application of negative external voltage to the electronic musical structure increases both the stiffness and the buckling load of the musical system. Furthermore, reinforcing the electronic musical structure with ZnO nanoparticles results in an increased buckling load. Notably, the maximum enhancement in the 28-day compressive and tensile strengths of samples containing zinc oxide nanoparticles compared to the control sample resulting in increases of 18.70% and 3.77%, respectively.

  • 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.

  • The purpose of this study is to analyze musical songs from an academic perspective by applying vocal techniques that can express songs in depth in three dimensions. Singing a musical song cannot be completed with just the musical part, rather, it should be accompanied by the analysis of various aspects such as the emotional state of the scenes and the characters. To this end, this study performed a multi-dimensional analysis of fields such as theatrical structure, lyrics, musical structure, and dynamics. In addition, the study explored and applied Estill Voice Training(EVT) that actors can best express songs with the emotions of the theater and music. EVT categorizes voice into six tones: speech, sob/cry, falsetto, twang, opera, and belting. In this study, in addition to these six sounds, the positions of vocal cords and larynx were also applied to seek ways to effectively express songs using "Gar Nichts" from the musical "Elisabeth" as a case study. "Gar Nichts" is a song sung by the protagonist Elisabeth, which expresses the self and the conflict at the peak of pain. Musically, this song requires various sound and voice-changing techniques to cover the range of "G#3-Gb5." As a result, it was confirmed that in order to embody the emotions of the characters and the songs in depth, the analysis of scenes and characters as well as various singing techniques need to be applied in harmony.

  • In some previous works on musical genre classification, human experts specify segments of a song for extracting musical features. Although this approach might contribute to performance enhancement, it requires manual intervention and thus can not be easily applied to new incoming songs. To extract musical features without the manual intervention, most of recent researches on music genre classification extract features from a pre-determined part of a song (for example, 30 seconds after initial 30 seconds), which may cause loss of accuracy. In this paper, in order to alleviate the accuracy problem, we propose a new method, which extracts features from representative segments (or main theme part) identified by structure analysis of music piece. The proposed method detects segments with repeated melody in a song and selects representative ones among them by considering their positions and energies. Experimental results show that the proposed method significantly improve the accuracy compared to the approach using a pre-determined part.

  • The purpose of this study is to examine the transformation and characteristics of the Verse-Chorus form. The musical form of a musical song is a structural mechanism for expression to effectively convey the dramatic situation of the characters to the audience. This study identified four types of representative forms that can be used to explore the transformation with the verse-chorus form and examined their characteristics. First is the Verse-Chorus form which repeats the description of simple situations and characters in the early stage of the musical. Second is the Verse-Bridge-Verse form which is used to evoke the atmosphere and escape boredom through a slight transformation of the bridge while explaining a simple character. Third is the Verse-Prechorus-Chorus form, which sits just before the chorus, connects the verse and the chorus, and promotes the emotional rise of the characters by smoothing the drama and the harmonic progression. Lastly, this study examined the expanded Verse-BG dialogue-Chorus form used to represent the situation in which conflicts about the complex feelings of the characters and the decisions about them coexist. As such, musical songs use various types of verse-chorus forms. Through the formality and transformation of the verse-chorus, the logic of the music and the logic of the drama are balanced so that the development of the music and the drama does not enter the state of imbalance. Based on this study, further progressive research can take place on the correlation between musical form and dramatic structure, beyond the transformation of musical song form.

  • In this paper, we proactively looked at the structure and characteristics of each instrument in order to compare and analyze the sound colors of the western violin, chinese erhu and korean haegeum, which are representative bow string instruments. Also, many performers have simply been unable to fully explain how the violin is rich in pitch and the haegeum has a unique tone. Also, many performers thinks that violin sounds rich just because it has many overtones and have been unable to fully explain how haegeum makes unique tone. While previous research data show that most instruments are studied and published by analyzing their own frequencies or related cases of acoustic studies, this study provides a visual look how the harmonics composition, which determines musical instruments' timbres, consists of and suggests data specifically by analyzing each sound pressure of integer multiple overtones so that the structure of instruments' unique timbre can be understood. Based on this, we hope that it will be of considerable help to the development of virtual musical instruments of korean traditional instruments, which are relatively small compared to western virtual instruments, by reproducing instrument sounds through the synthesizers in the future.

  • According to the findings of the study, the music composition of the mask play is deeply related to the main characteristics of the scene. The first scene of the play starts with the Byeoksa dance. This particular dance part represents the evil spirit expel ritual. The instrumental accompaniment like and are played for the dance. The last part of the play starts with the Halmi and Yeonggam scene. This scene is played in both the instrumental and vocal music. For the instrumental part , for the vocal part and songs are played. and songs are played on the part of the Halmi's funeral ceremony scene. The instrumental and are played in various scenes for the accompaniment of the dance part. The musical structure of the mask play is flexible. This kind of flexibility of scene structure mainly concerned with the way of musical composition. The main structure of the mask play can be classified into two main styles according to the allocation of the vocal music. In first style, the vocal music is evenly dispersed. In second style, the vocal parts are concentrated in the rear section. As I mentioned earlier, no logical association is found in the matter of the scene arrangement. A scene arrangement has a deep connection with the arrangement of the music in each scene. In conclusion, the mixed arrangement of the scene in mask play is mainly concerned with the matter of the music arrangement in order to maintain the tension of the drama.

  • Music copyright began in 1850 in France and, unlike other copyrighted works such as architecture or arts, which are based on visual conditions, copyrighted music is based the on trends of the times. The appropriate range of protection for musical works is not the entire music, but the part that is determined to be a creative expression deduced from the analysis of the musical structure. Concerning the issue of plagiarism in popular music, the determination of creativity plays an important role in whether a piece of music encroaches on the original copyrighted works or not. However, determining whether a work is an element of a previously copyrighted work should be achieved through a consensus formed by members of the relevant industry and academia rather than the court. The purpose of this study is to classify the creative and non-creative elements of popular music, in order to create a classification that can enable musical creators to provide a consensus on the elements of creative expression.

  • This is the first study in Musicology that discusses the features of Kangwon Sangkangrye(the pre-lecture ritual in Buddhism). In this thesis, I reviewed and compared the similarity and uniqueness between Kangwon Sangkangrye in "Seokmunuibom" and the one being performed these days. The musical relation between the performance shown in the historical record and the one in contemporary ritual was illustrated here based on the findings derived from the anlaysis on its bell(小鐘) performance. The analysis made upon musical sources recorded on-site shows the characteristics of contemporary Kangwon Sangkangrye. Following is a brief summary of this study. The review and comparison between Kangwon Sangkangrae in "Seokmunuibom" and the one being performed these days showed that the second type, which was significantly different from the first type, was closer to that of the historical record. The performers at Unmunsa Temple and Chungamsa Temple seemed to be following the tradition bell(小鐘) performance style which was found in the text of the historical record. Through the analysis on Kangwon Sangkangrae, I found that it has musical characteristics as follows. The vocal range of type 1 and type 2 was mostly performed within Minor 7th and didn't exceed the perfect 8th. The melodic structure of type 1 starts with do'-la of naedeureum and ended with the melody which downscaled from do' and finalized from mi to la. Usually the mode was in menari-tori but at some lecture halls a few cases found to be upscaled from sol to la which differentiates it from the typical menari-tori of folk songs. Like the typical way of traditional rites, the singing was divided into two parts: the leading call and the following choral response. Most were sung to be one syllable on one or two tones or one syllable lasting for several tones and the musical forms were varied by musical pieces. Meantime, Sangkangrae at Haeinsa Temple was differed from that of the other temples in terms of ritual procedure and vocal style. It added Korean version of and the lead vocal skipped the first phrase of the Sasul. The melodic structure of Type 2 started with do'-la of naedeureum and was finalized as the same way of Type 1. The mode of was not the same as typical menari-tori but the Jeongrye(prostration) and Balweon(a great vow) were identical to the menari-tori of folk songs. The singing was done in two forms, solo and unison, and the lyric-attachment of Gesong was one syllable for one or two tones and that of Jeongrye and Balweon were one syllable for one or two tones + one syllable for several tones. The musical form of Jeongrye is A-B-C and A-C. Balweon didn't display a certain periodicity but still maintained sense of unity and formality through repetition of the finalizing melody.

  • This paper aims to illustrate and illuminate the relationship between language and its neighbor disciplines, in particular between language and literature, language and religion, and language and music. 1. Language and literature. Literature is an art of language. Therefore, linguistics, the science of language, should be able to explain how the grammar of literature elevates and ordinary language into a literary language. I illustrate poetic syntax with examples from Shelley, Coleridge, and Wordsworth. 2. Language and religion. I show how a linguistic analysis of a religious text can illuminate the background, authorship, chronology, etc., of a religious text with an example from the Book of Daniel. I also illustrate how a misanalysis of a poetic meter led to a mistranslation with an example from the Book of Psalms. 3. Language and music. First I trace an epochal event in the history of the Western music, i.e., the change of the musical style from the liturgical music of Latin in which the rhythm was created by the alternation of syllable duration into the liberated music of German in which the rhythm was generated by the alternation of lexical stress. I then illustrate a parallelism between linguistic and musical structures with several musical pieces including Gregorian chant, the 16th century music of Palestrina, the 17th century music of Schutz, the 18th century music of Mozart, and the 19th century Viennese music. Finally, the importance of text-tune (verse-melody) association is discussed with examples of mismatches in translated Korean hymns and contemporary Korean lyrical songs. In the concluding part, I speculate on some factors that are responsible for the same organizational devices in three different modes of human communication. An answer may be that all are under the same laws of mind that govern the way man perceives and organizes nature, i.e., the same cognitive abilities of man, in particular, the capacity to organize and impose structure on their respective inputs.
