Readers will meet along the way a diverse cast of composers, musicians and performers who all make music in different ways in a variety of different genres, from Bach to Billie Eilish, Mozart to Miriam Makeba. Why do we make music? Which instruments make up a classical orchestra? How does music affect our brains and emotions? These are just some of the fascinating questions addressed in this book, which looks at music's transnational and boundary-breaking qualities. All over the world and throughout time, music has been recorded and passed down through different oral traditions and forms of notation. It has always been a powerful catalyst for influencing change and connecting people. And what might the future of music hold? Exploring the technology we use to listen to and create music, the authors imagine new possibilities such as computer-generated compositions and robot musicians.
