Iannis Xenakis in Argentina: Reception, Dialogues, and Exchanges

Iannis Xenakis visited Argentina as a professor of the Centro Latinoamericano de Altos Estudios Musicales (CLAEM) of the Torcuato Di Tella Institute in 1966 where he discussed his interdisciplinary interests – mathematics, architecture, and computer-aided composition. Using archival resources and oral history, this article explores three aspects of Xenakis's trip to Argentina. First, the way the media framed the visit of the European composer and the reception of the events organized around it under a modernist discourse. Second, the direct impact that this visit had on some of the composers at CLAEM, particularly Graciela Paraskevaídis. Finally, the exchanges that Xenakis had with engineer Fernando von Reichenbach, who had been working on transforming graphic material into sound, something that crystallized with the development of Reichenbach's Convertidor Gráfico Analógico (1969), and Xenakis's Unité Polyagogique Informatique CEMAMu (UPIC 1977).
