Augusto de Campos - Música de Invenção, published by Editora Perspectiva, São Paulo, Brazil, 1998.
Música de Invenção (or, Creative Music) collects articles written by Brazilian concrete poet Augusto de Campos between 1957 and 1997 as well as collages and designs by the author, like the Schönberg portrait above.
Chapter 1, titled “Palavra e Música”, is about Renaissance music in Provence (Northern Italy and Southern France) and its influence on some 20th century composers, like Ezra Pound, especially his Le Testament chamber opera. This chapter also examines Virgil Thomson’s Four Saints in Three Acts, with a libretto by Gertrude Stein ; American vilolinist Olga Rudge ; and Schönberg’s Pierrot Lunaire. Chapter 2 “Radicais da Música” gathers articles on some of 20th century most original composers like Erik Satie, Scott Joplin, Walter Smetak, Anton Webern and Edgar Varèse. Chapter 3 “Musicaos” collects articles on John Cage. Chapter 4 “Pós-Música” examines the work of Giacinto Scelsi, George Antheil, Luigi Nono, Conlon Nancarrow, Henry Cowell and Galina Ustvolskaia.
The boook looks like a great introduction to some of the most original composers of 20th century and an English translation seems necessary.
