Pepper is the humanoid robot that supports teachers and students in MUSIC4D as an innovative mediator between technology and creativity. Equipped with adaptive AI, speech recognition, multimodal interaction, and nonverbal expressive capabilities, Pepper is designed to accompany educational and musical processes in an empathetic, engaging, and personalized manner. In the experimental labs of the Palermo Conservatory, in collaboration with the University of Palermo’s Engineering Department, Pepper actively participates in didactic modules on assisted composition, interactive solfeggio, environmental sound design, and orchestral simulation. Its presence fosters dialogue between students and emerging technologies, transforming the learning experience into an immersive, dynamic, and motivating environment. Pepper does not replace the teacher, but acts as a relational and pedagogical tool, embodying MUSIC4D’s vision of a future in which humans and machines co-create new forms of musical expression.
