An EEG Neurofeedback Interactive Model for Emotional Classification of Electronic Music Compositions Considering Multi-Brain Synergistic Brain-Computer Interfaces

This paper presents an in-depth study and analysis of the emotional classification of EEG neurofeedback interactive electronic music compositions using a multi-brain collaborative brain-computer interface (BCI). Based on previous research, this paper explores the design and performance of sound visualization in an interactive format from the perspective of visual performance design and the psychology of participating users with the help of knowledge from various disciplines such as psychology, acoustics, aesthetics, neurophysiology, and computer science. This paper proposes a specific mapping model for the conversion of sound to visual expression based on people’s perception and aesthetics of sound based on the phenomenon of audiovisual association, which provides a theoretical basis for the subsequent research. Based on the mapping transformation pattern between audio and visual, this paper investigates the realization path of interactive sound visualization, the visual expression form and its formal composition, and the aesthetic style, and forms a design expression method for the visualization of interactive sound, to benefit the practice of interactive sound visualization. In response to the problem of neglecting the real-time and dynamic nature of the brain in traditional brain network research, dynamic brain networks proposed for analyzing the EEG signals induced by long-time music appreciation. During prolonged music appreciation, the connectivity of the brain changes continuously. We used mutual information on different frequency bands of EEG signals to construct dynamic brain networks, observe changes in brain networks over time and use them for emotion recognition. We used the brain network for emotion classification and achieved an emotion recognition rate of 67.3% under four classifications, exceeding the highest recognition rate available.

Idris Sardi’s Influence on Musical Development and Education in Indonesia

Idris Sardi is known as a music maestro in Indonesia. This study aims to reveal the influence of Idris Sardi on the development of music and its implications in music education. This study uses a qualitative method with a narrative approach. The data were collected through observation, in-depth interviews, and documentation. The research informants were carefully selected from the family, violin students, and colleagues of Idris Sardi in Jakarta and Bogor, West Java. The data were analyzed by organizing data and creating codes, describing codes in chronological categories and themes, developing interpretations, and visualizing data. The results showed that Idris Sardi was influential in developing (1) keroncong music by varying the tempo and expanding the repertoire; (2) the violin playing techniques included unique characters such as vibrato, glissando, and octave variations; (3) ethnic and popular music were made through orchestrations and collaboration with orchestral music. The implications in music vocational education were (1) problem-based learning by creating a new keroncong style to be accepted by society; (2) the improvement capability by exploring skills to play the violin; (3) life-based-learning by raising local and popular music to be qualified while enhancing the level of society’s music appreciation. In conclusion, Idris Sardi provided a strong influence on the music development in Indonesia, and the implication could be a new strategy to improve the quality of music education.

The value of music in liberal arts education and integrating musicing into a music appreciation course

A liberal arts education for Christians is about finding God’s truth; therefore, Christian students need to be educated in a broad range of subjects, including music. While a music appreciation course is thought to be about gaining knowledge of music, some music scholars have pointed out that a music curriculum should involve students in experiencing the essence of music through doing. This article discusses God’s invitation for us to music and the value of music in a liberal arts education. In addition, it looks at the integration of a praxial approach (referred to here as musicing) in a music appreciation course.

Consuming and collecting records in Spain, 1896–1905

This chapter draws upon the five major surviving collections of Spanish early recordings in order to attempt to reconstruct who bought wax cylinders in Spain around 1900, what their motivations were and what their listening and collecting practices looked like. It discusses how record buyers were still a small, privileged minority in Spain at the time, and examines how collecting might have helped developed ways of listening focused on music appreciation rather than on purely replicating a collector’s live music experience. It also analyzes home recording practices, which were a significant part of phonograph marketing strategies at this time.
