This book provides a unique overview of the entire oeuvre of Heinz Holliger (born 1939) - from his early works to his most recent compositions. The chosen focus 'Language, Breath, Silence,' which strikes at the core of Holliger's work and shapes not only his vocal but also his instrumental creations, allows for an in-depth insight into his choice of texts (such as Hölderlin, Trakl, Walser, Sachs, Celan, Beckett) as well as his pursuit of overarching connections. The compositions analyzed in detail are selected to ensure both thematic diversity and a balanced representation of the corresponding developmental phases. The multifaceted personality of the composer is highlighted through the inclusion of longer interviews and comments from Holliger embedded in each chapter. Each chapter usually begins with an introduction that presents and relates all works of the relevant context. The subsequent analyses progressively delve deeper from an overall positioning into more detailed examination.
