This book is all about the musical creativity as inspired by the sense of tonality, throughout the history of music in Europe, since Monteverdi, and all over the world nowadays. As a text that is “musico-sophical” instead of being “musico-logical,” it is inspired by the founder of phenomenology, Edmund Husserl (1859–1938), and his philosophical seizure of consciousness. It discusses the author’s journey in the world of music and describes “musical consciousness” and the ways in which it moves and works within us. The book presents to the readers the author’s account of the composers he met along the way (Slamet Sjukur, Giacinto Scelsi) and the composers who are currently active (Jean-François Laporte, Pierre Michaud, Myriam Boucher, George Benjamin), along with historical narratives that center around Monteverdi, Bach, Debussy, Ravel, and Bartok. It underlines the interrogations held by today’s musicians in light of yesterday’s mutations. With this book, the author would like to reach out to composers, performers, and music lovers and contribute towards opening them to the scope of experimentation in music and in the world of sound, all of which keep on becoming more expansive and more intensely conscious.
