This study examines the development and limitations of current artificial intelligence (AI) music composition programs. AI music composition programs have progressed significantly owing to deep learning technology. However, they possess limitations pertaining to the creative aspects of music. In this study, we collect, compare, and analyze information on existing AI-based music composition programs and explore their technical orientation, musical concept, and drawbacks to delineate future directions for AI music composition programs. Furthermore, this study emphasizes the importance of developing AI music composition programs that create "personalized" music, aligning with the era of personalization. Ultimately, for AI-based composition programs, it is critical to extensively research how music, as an output, can touch the listeners and implement appropriate changes. By doing so, AI-based music composition programs are expected to form a new structure in and advance the music industry.

ADHD (Attention Deficit Hyperactivity Disorder) appears most in childhood and shows attention deficit, hyperactivity and impulsive activity. If these symptoms are left untreated, they consistently remain as difficulties throughout the childhood and in some cases they will last until adolescence and adulthood. Various researches on music therapy as well as psychological therapy and Korean classical music appreciation have currently been conducted. However, a variety of programs have introduced in the name of treatment but the improvement results through the application of programs and teaching methods, in reality, have hardly been a specific case. Thus, music educators as well as this researcher should make the efforts to form holistic characters and have interest in countless children with ADHD. Accordingly, this researcher, who has taught piano lessons, has performed a wide variety of convergence art teaching methods by applying methods of Dalcroze, Kodaly, and Orff to children with ADHD, misanthropy or lack of affection. As a result, symptoms have lessened and been treated for ADHD children with attention deficit. On the basis of this experience, there have appeared more educational effects by applying these to other children. This researcher is certain that this study will a foundation of music therapy education for children with each kind of syndrome.

This study analyzes Cho, Yong- Pil's contribution on K-Pop history as he celebrates the 50th anniversary of his debut. The history of K-Pop, when Cho has been active in, is divided into three periods. From the late 1960s to the early 1980s was a period when trots and rocks were popular. Soft rock, heavy metal, and ballads came in from the mid-1980s to the early 2000s. From the late 2000s to the present, dance music, mostly hook songs, has dominated. In every inflection point of K-Pop history, he contributed to the development throughout various musical genres. In the first period, he introduced rock music with the unique emotion of Korea by combining the trot and the rock genre. In the second period, he contributed to the development of both rock and ballad genres. In the third period, his hook songs were released to the controversy, but it contributed to creating an atmosphere in which the vocal ability of the vocalist in idol groups was emphasized in the K-pop scene.

In this paper, we propose a system that recommends music through tempo-oriented music classification and sensor-based human activity recognition. The proposed method indexes music files using tempo-oriented music classification and recommends suitable music according to the recognized user's activity. For accurate music classification, a dynamic classification based on a modulation spectrum and a sequence classification based on a Mel-spectrogram are used in combination. In addition, simple accelerometer and gyroscope sensor data of the smartphone are applied to deep spiking neural networks to improve activity recognition performance. Finally, music recommendation is performed through a mapping table considering the relationship between the recognized activity and the indexed music file. The experimental results show that the proposed system is suitable for use in any practical mobile device with a music player.

This study is conducted for the purpose of conceptualizing a choral communication model. first, the musical communication models analyzed to know how it can apply in the choral music. As a result, we take the music communication is the interaction between composers, performers and audience. But the choral music have properties not found in the general music. The choral music is the need for internal communication process before performing music. First, the conductor is to interpret the music. Next, choral members are shared the interpretation of music. This internal communication be conducted properly, musical communication with the audience will be successful. The trial model provided for in this study will be a guideline for successful communication in the choral music, theoretically or practically.
