The editorial categories are research topics that have guided researchers during the recovery phase and continue to be the impetus behind the Documents Project’s digital archive and the Critical Documents book series. Developed by the project’s Editorial Board, each of the teams analyzed this framework and adapted it to their local contexts in developing their research objectives and work plans during the Recovery Phase.

Hans-Joachim Koellreutter wrote this letter from Teresópolis, Brazil, in August 1950. In it, the German-Brazilian composer mentions the research he is doing, exploring new relationships between sounds that will lead to a Madí style of music.
Arte Madí Universal magazine was published from 1947 until June 1954. Gyula Kosice (1924-2016) was the Editor, and he was assisted by: Rhod Rothfuss, Diyi Laañ, H.-J. Koellreutter, Masami Kuni, Valdo Wellington, Alberto Sartorio, Alberto Hidalgo, and M. G. de la Fuente, among many others. The School’s Manifesto appeared in the first issue. Hans-Joachim Koellreutter (1915-2005) was a flautist, musical director, and composer who was born in Germany and settled in Brazil. He constantly encouraged a process of renewal in music, and founded the Música Viva [Live Music] association. In about 1950 he was researching a formula that dealt with both the chromatic scale and its intervals, with a view to using it in his own musical compositions. This particular document has been chosen because it confirms the communicational link that existed between Brazilian and Argentine artists, and reveals the parallel explorations being conducted by visual artists and musicians at the time.
