Between 1971 and 1989, fifteen editions of the Cursos Latinoamericanos de Música Contemporánea (Latin American Contemporary Music Courses) took place alternatively in five countries of the continent. These were intensive meetings concentrated in two weeks, consisting of classes, workshops, seminars, conferences, and concerts. One of the central concerns was contemporary art music composition, although an important space was also given to performance, technologies, innovative pedagogies, popular music, and musicology. Around 150 lecturers from different countries took part in the courses, among them, about forty-five were European. On the one hand, the courses aimed at providing updated information on contemporary international musical life. On the other hand, they encouraged its critical evaluation in relation to the history, culture, and concrete practices of Latin American musicians. This article analyses exchanges between Latin American and European musicians regarding compositional techniques, theoretical perspectives, repertoires, aesthetics, and ideological positions during the 1974 and 1977 editions of the Cursos.
