In this paper, a novel approach is proposed to improve the performance of speech/music classification using the recurrent neural network (RNN) in the enhanced voice services (EVS) of 3GPP for hearing aids. Feature vectors applied to the RNN are selected from the relevant parameters of the EVS for efficient speech/music classification. The performance of the proposed algorithm is evaluated under various conditions and large speech/music data. The proposed algorithm yields better results compared with the conventional scheme implemented in the EVS.

In this Paper, we propose a content-based music information retrieval (MIR) system base on the query-by-example (QBE) method. The proposed system is implemented to retrieve queried music from a dataset where 60 music samples were collected for each of the four genres in Classical, Hiphop. Jazz. and Reck. resulting in 240 music files in database. From each query music signal, the system extracts 60 dimensional feature vectors including spectral centroid. rolloff. flux base on STFT and also the LPC. MFCC and Beat information. and retrieves queried music from a trained database set using Euclidean distance measure. In order to choose optimum features from the 60 dimension feature vectors, SFS method is applied to draw 10 dimension optimum features and these are used for the Proposed system. From the experimental result. we can verify the superior performance of the proposed system that provides success rate of 84% in Hit Rate and 0.63 in MRR which means near 10% improvements over the previous methods. Additional experiments regarding system Performance to random query Patterns (or portions) and query lengths have been investigated and a serious instability problem of system Performance is Pointed out.

Recently, there are so many music school graduates. In addition, there are many private music institutes. For this reason, there is a fierce competition in music education market. In the past, those who worked in music education market earned big money and so many parents wanted their girls and boys to learn playing a piano and other musical instruments. In the recent times, however, birth ratio was reduced dramatically in Korea and parents do not want their children to learn musical instruments due to economic depression and deteriorated music market. Eventually, the size of music education market was diminished dramatically and the competition in music education market is getting fiercer. Therefore, it is difficult to expect good performance in music education market without having an improved management system. In this respect, this study aims to understand what main factors have an impact on business performance in music institutes. The main areas studied in this paper include successful factors, reason why they start up a business, and successful management factors. The survey of this study targeted music institute owners. Based on the surveyed results, for the owners of the music institute, the method of the venture management approach, in other words, the application of the marketing knowledge, the consideration of the company system, the application of the smart technologies, etc., has been presented.

Korean traditional music has been a process art which has been changed and re-created by musicians to mirror the musical aesthetics of contemporary people. Form court music, which has tried to keep the "authentic" form as much as possible, to folk music, which is closely associated to the people's life style, traditional music has expressed the life of the Korean people. From the early 20th century, traditional music faced a totally new music culture due to the Japanese annexation and rapid westernization. A new music network was established by modern theater and broadcast system. Many gayageum (12-stringed zither) masters were able to develop their own music in this new music culture. Female musicians came to exist because of a new music education system, called gwonbeon (school for female entertainers). Due to the rapid westernization, traditional music was becoming 'extinct'. The government's new system of Intangible Cultural Heritage tried to preserve traditional culture. Traditional music came to revive but became fossilized in order to preserve the 'archetype'. The so-called Living Human Treasures took power and became a social problem. The modern school education system was one of major factors for promotion of traditional music. However, it became one of main reasons for musicians to lose their musical creativity. Today, many performers and composers try to make a new composition and renovated musical instruments to suit the contemporary musical aesthetics.

Since the beginning of the 90's, Fashion shows appear to be a type of performance form of art combining with other areas to visually entertain the viewers. This can be explained by the modern tendency to escape from society which requires formality and complicated lifestyles. Fashion shows take place in a scene Influenced by the idea of post-modernism which redefines the definition of space. A church, old factory, unoccupied ground, subway stations, or even place like a waste disposal are used as a setting. The stage set is no longer the T shape run way and the procinium arch has disappeared. The gap between audience and stage has diminished and theatrical element is added to the fashion performance by using viewers living and working environments as setting of the show. The human relation with machine based on the cutting edge technology such as the stage automation, robots and mist making sprinkler system introduces new elements with spontaneity and detailed planning in the stage performance. Music also plays an Important role in attracting viewers. The sound track covers house music to techno music. Instead of music being abstract, folks orchestral music, choirs, piano. even live concert performed by pop artist provide the liveliness of the fashion show. And the catwalk itself is a performance. Model needs to be well trained as the capable talent who can handle sensitive gestures, facial expressions, dancing and choreography. The improvisatorial interaction between audience and model lead to audience participation. Models now range from pop star, ordinary people, handicapped people, to elderly and so on. John Galliano introduced the theatrical factors for the fashion show and Alexander Mcqueen approached the fashion show as the visual art of communication. Hussein Chalayan utilized high technology skewing futurism as if in a magic show. Today the Fashion show tends to be a total performance which includes audience participation, impromptu, and that break the limitation that fashion shows previously had. This will lead the fashion industry in opening new horizon of its own.

The role of bass in band or ensemble music literally sets up the foundation of harmony, which must be regarded first. On the other hand, this is also considered so basic or stable that it can be slightly boring to the listeners. Consideration is needed to make the varied trials more exciting. In this sense, Rutger Gunnarsson showed these fine examples not in performing music but in pop music through the Great ABBA. He could make a fabulous sound with only a basic performance, not with a florid technique or rhetorical skills. All bassists must bear in mind that the overall performance depends on the bass. In short, to make better music, remember to practice continually and find better methods.

Many Korean traditional music such as Jongmyo Jeryeak and Pansori are listed as UNESCO World Intangible Cultural Heritage and are recognized for their value. However, compared to other genres, Korean traditional music shows various problems such as low proportion of paying audiences and bias of audience age. Previous studies in the performing arts point out that in order to solve these problems, it is necessary to analyze consumers. Existing previous studies on the Korean traditional music performance remained mainly to grasp the influence of performance quality of service on viewing satisfaction at the one-dimensional level. However, in order to meet consumer expectations, not only the satisfaction factor but also the reasons why performing art consumers do not consume performances. In addition, it is important to identify the factors that can cause service failure before the performance, to prepare countermeasures and to manage them continuously. In this study, the Kano-Timko model was used to classify the quality factors of Korean traditional music performances, and to identify the priority points of service failures of Korean traditional music performances through the potential customer satisfaction index. Through the results of this study, Korean traditional performing organizations and organizations will be able to prepare proactive countermeasures for service failures occurring in Korean traditional music performances and establish effective operational strategies to derive customer satisfaction. In addition, it is important to apply the concept of service failure in order to classify the performance quality of service that was identified only in a one-dimensional manner based on Kano model.

This paper proposes an automatic genre classification system for Korean traditional music. The Proposed system accepts and classifies queried input music as one of the six musical genres such as Royal Shrine Music, Classcal Chamber Music, Folk Song, Folk Music, Buddhist Music, Shamanist Music based on music contents. In general, content-based music genre classification consists of two stages - music feature vector extraction and Pattern classification. For feature extraction. the system extracts 58 dimensional feature vectors including spectral centroid, spectral rolloff and spectral flux based on STFT and also the coefficient domain features such as LPC, MFCC, and then these features are further optimized using SFS method. For Pattern or genre classification, k-NN, Gaussian, GMM and SVM algorithms are considered. In addition, the proposed system adopts MFC method to settle down the uncertainty problem of the system performance due to the different query Patterns (or portions). From the experimental results. we verify the successful genre classification performance over $97{\%}$ for both the k-NN and SVM classifier, however SVM classifier provides almost three times faster classification performance than the k-NN.
