This book advocates for a radical change in music teaching and learning methods, allowing for a break from the traditional conservatory model still in use in many classrooms. The product of twenty years of interdisciplinary work by musicians, music teachers, and psychologists, the book proposes to place the focus of music education on the students themselves and on their mental and physical activity, with the aim of helping them to manage their own goals and emotions. This alternative is based on a new theoretical framework, as well as numerous real, concrete examples of how to put it into practice with students of different ages and in different environments. This book focuses primarily on teaching instrumental music, but its content will be useful for any teacher, student, musician, or researcher interested in improving music education in any environment, whether formal or informal, in which it takes placeChapters 3, 4, 6 and 18 are available open access under a Creative Commons Attribution 4.0 International License via link.springer.com.
