By the time he was nine, having already acquired a considerable
knowledge of music, Rosenmann-Taub started giving piano lessons. He
continued his own pianistic education with Roberto Duncker, and took
lessons in rhythm and music theory from Andrée Haas (a student of
Émile Jaques-Dalcroze), in harmony from Samuel Negrete, and in musical
methodology from Carlos Isamitt. His teacher in composition,
counterpoint, and fugue was the great Chilean composer
Pedro
Humberto Allende .
Although he began recording in the 1950s, it was only in the 1990s, when a grant provided the necessary studio time, that he was able to commit a sizeable portion of his work to tape. The dissemination of his music, which fills over a hundred CDs, was launched in April, 2006 with the release of En un lugar de la Sangre, a multimedia composition consisting of a book of poems, two compact discs of music and poetry, and a DVD video of the composer playing selections of the music. To view a sample from this DVD, please see the video portion of the recordings page.
