This research presents a mapping out of Brazilian electroacoustic music studios from 1960 to 2000, especially those that emerged in connection with universities and other institutions. A major criterion was to understand “music studios” as cultural territories, as places for creation, collaboration, and exchange. We present a timeline highlighting the main trajectories of composers, institutions, and events, all related to the development of these studios. We interviewed composers and investigated a wide variety of documents, ranging from scholarly papers and journal articles through books, recordings, and websites. As a result, the timeline introduces the main spaces that have fostered electroacoustic music in Brazil, revealing the idea of gambiarra [make do, workaround], a sort of Brazilian DIY culture.
