The effect of pitch on tone durations was studied in several poeces of music. In previous work it was found that higher pitched sounds, of a given duration, were perceived to be of longer duration. That work however, was not undertaken in a musical context. The present work was done to determine whether the previously observed trend was also apparent in musical performances. Several measurements were undertaken. One of these involved analysing the recorded performance duration of notes in several performances of the Mozart Flute Quartet in A-mojor, K.298. Performed durations were also obtained from a Bach Flute Sonata and a Brahms Clarinet Quintet. An analysis of the musical performances revealed that while there were individual differences and exceptions in notes, the musicians tended to play higher notes significantly shortened.

The Bible has been and still is one of the most influential books ever published. The English Bible has a great impact on English language, literature, and culture. Therefore, knowledge of the Bible is essential in learning English language, its literature, culture and tradition. Biblical allusions are found in great literature and the daily newspapers as well. Rock musicians, screenwriters, television producers, and advertisers use the Bible as a source. Politicians use the words and accounts of the Bible to frame their debates. The Bible has continued to be philosophically, ethically, religiously, and politically influential in Western, Eastern, now World cultures. Therefore, not to know it means not to understand a great portion of world culture. This study examines the influence of the first book of the Bible, Genesis, in English language, literature, and culture. Furthermore, this study suggests why we should incorporate the English Bible in English education.

While the difficulty of the music can be classified by a variety of standard, conventional methods are classified by the subjective judgment based on the experience of many musicians or conductors. Music score is difficult to evaluate as there is no quantitative criterion to determine the degree of difficulty. In this paper, we propose a new classification method for determining the degree of difficulty of the music. In order to determine the degree of difficulty, we convert the score, which is expressed as a traditional music score, into electronic music sheet. Moreover, we calculate information about the elements needed to play sheet music by distance of notes, tempo, and quantifying the ease of interpretation. Calculating a degree of difficulty of the entire music via the numerical data, we suggest the difficulty evaluation of the score, and show the difficulty of music through experiments.

The history of architectural acoustics is a part of history of human being getting together for both politics and entertainments, is also a part of the history of nobility pursuing hearing enjoyments, is still a part history of scientists deeply understanding the concept of "just for people", and as well as is a part history ceaselessly driven by the musicians to find their real hearts through music. The history of architectural acoustics explains not only the acoustic knowledge developments in architectural design, but also the unity on contradictory of both the science and the arts, both the technology and the culture, both the sense and sense organ. The history of architectural acoustics prints the interactions between the mankind and the nature, between the mankind and themselves, between the mankind and their souls, in which course people understand their feelings more deeply and deeply. This paper discusses the brief history of architectural acoustic in China from the ancient drama stages to grand theaters in 20 century, even up to nowadays, including some most important buildings and events as well.

Harmony search (HS) is a relatively recently developed meta-heuristic optimization method imitating the music improvisation process where musicians improvise their instruments' pitches searching for a perfect state of harmony. In the conventional HS algorithm, it is necessary to determine the maximum number of iterations with some algorithm parameters. However, there is no criterion for determining the number of iterations, which is a very difficult problem. To solve this problem, a new method is proposed to perform the algorithm without setting the maximum number of iterations in this paper. The new method allows the algorithm to be performed until the desired tuning is achieved. To do this, a new variable bandwidth is introduced. In addition, the types and probability of harmonies composed of variables is analyzed to help to decide the value of HMCR. The performance of the proposed method is investigated and compared with classical HS. The experiments conducted show that the new method generally outperformed conventional HS when applied to seven benchmark problems.

A musical key is a fundamental concept in Western music theory. It is a collective characterization of pitches and chords that together create a musical perception of the entire piece. It is based on a group of pitches in a scale with which a music is constructed. Each key specifies the set of seven primary chromatic notes that are used out of the twelve possible notes. This paper presents a method that identifies the key of a song using Hidden Markov Models given a sequence of chroma features. Given an input song, a sequence of chroma features are computed. It is then classified into one of the 24 keys using a discrete Hidden Markov Models. The proposed method can help musicians and disc-jockeys in mixing a segment of tracks to create a medley. When tested on 120 songs, the success rate of the music key identification reached around 87.5%.

The aim of this study was to evaluate the synergistic effect of Samulnori and Ajaeng combination in music therapy. Samulnori is the Korea's most successful traditional music. The Ajaeng, Korean traditional string instrument, generally plays the bass part in ensemble music. However, we have tried a new kind of musical style. (As you can see in the Youtube, https://youtu.be/QHIciJTTY0w). Samulnori and Ajaeng combination of our style have not been tried by any other musicians in Korea. Results from this study showed that Samulnori-induced excitation and Ajaeng-induced dynamics probably contributed to the synergistic effect of Samulnori and Ajaeng.

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.

This study examines musical characteristics of so-called 'Hongdae Sound' as a historic musical trend by comparing with 'US 8^th Army Sound' and British 'London Punk'. Hongdae Sound refers to the musical trend that was formed with independent bands and musicians who mostly performed live in the club called 'Drug' in Hongdae area, and voluntarily adopted minor musical sensitivity and indie spirit of 'post-punk rock' genre. But as an industrial standpoint the superficial identity of 'indie' interferes with academic approach when analysing musical aspects of Hongdae Sound. Therefore it is necessary to rearrange its characteristics as the musical trend based on regional classification in order to fully appreciate its status in history of Korean popular music. US 8^th Army Sound refers to the musical trend that was played within the live stages in US military bases in Korea. Many hired Korean musicians for those shows were able to learn the current popular musical trend in the States, and to spread those to the general public outside the bases. The industrial system of the Army Sound was very similar to that of K-Pop, but when it comes to leading the newest musical trend of 'rock-n-roll', it had more resemblance to that of Hongdae Sound. London punk was the back-to-basic form of pure rock that was armed with social angst and rebel, indie spirit. Its primal motto was 'do-it-yourself', and Hongdae Sound mostly followed its industrial, musical and spiritual paths. London punk was short-lived because it abandoned its indie spirits and became absorbed to the mainstream. But Hongdae sound maintain its longevity by maintaining the spirit and truthfulness of indie, while endlessly experimenting with new trends.

Shin Gwang-su (申光洙, 1712~1775), also known as Seokbuk (石北), is a well-known poet and author of the song poetry (詩唱) "Gwanseo-akbu (Poems of the Gwanseo Region, 關西樂府)" in the late Joseon Dynasty. "Gwanseo-akbu" was popular among the Joseon Dynasty musicians. This fact confirms that the tradition of adding a melody to Shin Gwang-su's "hansi (Korean poetry recorded in Chinese characters, 漢詩)" already existed in the Joseon Dynasty. It is also a proof that the hansi poem was used in songs. Besides Seokbuk, other literary figures in the Joseon Dynasty wrote and sang hansi. In that case, the place of communication for songs was a poet's personal study, or "sarangbang." But when, like the works by Seokbuk, poems were sung by musicians, they became available to the public to communicate through music. This study is one of the attempts to re-make Seokbuk Shin Gwang-su's poems and songs, once popular among the Joseon Dynasty people, into the contemporary music that can be performed on stage. By adding a certain melody to his poems, this study introduces a case of musical work and offers an opportunity to consider hansi as performance art. There is a number of hansi works by Shin Gwang-su, and each poem includes material which can help survey Shin Gwang-su's musical life. And, working on his hansi works makes it possible to narrate major events that took place in Shin's life. Thus, this study attempts to focus Shin Gwang-su's musical life and introduces methods and contents to stage his hansi poems as performance art.
