In this paper, we propose a novel approach to improve the performance of speech/music classification for the selectable mode vocoder (SMV) of 3GPP2 using the discriminative weight training which is based on the minimum classification error (MCE) algorithm. We first present an effective analysis of the features and the classification method adopted in the conventional SMV. And then proposed the speech/music decision rule is expressed as the geometric mean of optimally weighted features which are selected from the SMV. The performance of the proposed algorithm is evaluated under various conditions and yields better results compared with the conventional scheme of the SMV.

For musical genre classification, various types of feature vectors are utilized. Mel-frequency cepstral coefficient (MFCC), decorrelated filter bank (DFB), and octave-based spectral contrast (OSC) are widely used as short-term features, and their long-term variations are also utilized. In this paper, OSC features are extracted not only in the single-octave band domain, but also in the multiple-octave band one to capture the correlation between octave bands. As a baseline system, we select the genre classification system that won the fourth place in the 2012 music information retrieval evaluation exchange (MIREX) contest. By applying the OSC features based on multiple-octave bands, we obtain the better classification accuracy by 0.40% and 3.15% for the GTZAN and Ballroom databases, respectively.

In this paper, we propose a new automatic taxonomy generation algorithm for the audio genre classification. The proposed algorithm automatically generates hierarchical taxonomy based on the estimated classification accuracy at all possible nodes. The estimation of classification accuracy in the proposed algorithm is conducted by applying the training data to classifier using k-fold cross validation. Subsequent classification accuracy is then to be tested at every node which consists of two clusters by applying one-versus-one support vector machine. In order to assess the performance of the proposed algorithm, we extracted various features which represent characteristics such as timbre, rhythm, pitch and so on. Then, we investigated classification performance using the proposed algorithm and previous flat classifiers. The classification accuracy reaches to 89 percent with proposed scheme, which is 5 to 25 percent higher than the previous flat classification methods. Using low-dimensional feature vectors, in particular, it is 10 to 25 percent higher than previous algorithms for classification experiments.

In this paper, the tone of Daegeum, one of the most representative wind instruments of our country, was analyzed. Daegeum is widely used as Jeongak Daegeum and Sanjo Daegeum, which are played in royal and wind music, and Sanjo Daegeum is mainly played in Sanjo, Sinawi and folk music. The reason why the two pieces of music are being played in different music genres is due to the improvement of the length of the pipe and the location of the finger holes, allowing the Sanjo Daegeum to perform faster than Jeongak Daegeum, apply various techniques, and make the choice of musical instruments harmonized with music by making the difference in tone. For timber analysis of Jeongak Daegeum and Sanjo Daegeum, the composition of the overtones was visually verified through Spectrogram and Spectrum Analizer, in which the results of recordings were recorded by playing octave low, flat, and octave high positions with the same power. From this, Jeongak Daegeum, which is rich in low-pitched sound, harmonizes with solemn music such as royal music, and Sanjo Daegeum, which has a relatively clear high-pitched sound, is well suited to bright music such as solo music.

Poem plays an important role in Ca trù. Many music researchers say that singing Ca trù is singing poem. Of 46 tunes of Ca trù, there are more than 10 tunes expressed in available poems or styles of poetry; for example: in the tune Tỳ bà, the performer could sing Tỳ bà hành by Bạch Cư Dị being converted into seven-seven-six-eight-word-meter; in the reciting poem tunes, just reciting 5 Thien thai poems by Tào Đường or 3 Thanh Bình tune poems by Lý Bạch; in the reciting poetic essay (phú), reciting Tien Xich Bich and Hau Xich Bich by Tô Đông Pha. Others like bắc phản, cung bắc sometimes used six-eight word meters. Structurally, those are available for familiar types and beyond the scope of particular creativity because they do not originate from Ca trù's activity environment like recitative. Recitative is the main tune of Ca trù and has become an independent poem type. In terms of literature, recitative has a particular form structure and special type content. Unlike other tunes of Ca trù that only stop at some fixed works, recitative has increased to thousands of works in quantity and has been composed for many centuries. For those reasons, we confined ourselves the research to the creation which is the most typical of Ca tru: The recitative.

This study aimed at examining the music world of the composer Muczynski, who played an important and meaningful role in the various experimental trends of music which began to appear in the early $20^{th}$ century, and his works, thereby understanding his relationship with the development of music of various genres today. In the study, his pieces of piano music among his works, which formed the basis for his music, were analyzed. The study examined stylistic characteristics, that is techniques of various types including form, melody, harmony, tonality, rhythm and structure, and introduced the composer's growth in terms of music and philosophical background. Muczynski, the composer who showed the characteristics of neoclassicism, neoromanticism and neobaroque in contrast to the various forms of the $20^{th}$ music, namely music of free styles including atonal music, twelve-tone technique, avant-garde music and electronic music, used traditional forms. However, the characteristics of his works are very free. In addition, in the 1960s, he participated in the production of documentary movie music, creating very creative and sensational music. Muczynski's music has the features of tonality and shows neoclassic and neoromantic features including economical idea, lyrical melody, bitonality and nine-note scale. His music, therefore, is being evaluated as very creative and valuable and is largely significant in that it has provided a good basis for the development of modern movie music and jazz music today.
