This volume sheds light on the wide range of perspectives on musical activity today, and shows how it can be analyzed from different points of view, working within a diverse theoretical framework. It is organized into three sections, the first of which discusses the changing contexts of musical work compositions over the 20th century. The second part offers a rich and in-depth musical analysis, rigorously connected to the performative and interpretative dimension, while the third considers the relationship between technology and music, and its influence on the creation of new paradigms for musical performance and creation. Covering practical and theoretical problems, the collection will be of great interest to scholars, professionals, students of music, composers, and performers.
