This chapter examines the emotional impact of music and its importance for musical development and education. It discusses different psychological understandings of emotion, the distinction between emotion perceived in music and emotion induced by music, and the difficulties involved in investigating these processes experimentally. The chapter argues that the emotional charge of music is not a secondary effect but a key mechanism through which musical experience acquires personal significance and motivational force. On that basis, it explains why the relation between music and emotion is crucial for childhood, adolescence, and pedagogical work. It therefore defends the view that emotional participation is a condition of lasting musical interest and meaningful learning.
