In Paris (1965-69) he studied with Nadia Boulanger, Olivier Messiaen and attended courses and lectures of Xenakis. In Germany he studied with Karlheinz Stockhausen [1968] and with György Ligeti [1972] He did a Ph. D. in Musicology at Strasbourg University (1990- 1994).

Since 1974 he became researcher in music at the Instituto de Estéticas, IIE/UNAM, where he was appointed as the Chair of a project on Mexican Music History and as the head of [1], "Música, Sistema Interactivo de Investigación y Composición", a musical system designed by himself. He is he first music scholar to be honored as member of the Science Academy of Mexico (), and by the Mexican Education Ministery as National Researcher [since 1984]. He created a Composition Seminar at UNAM, where he has been teaching Compositional Theory and Philosophy of Composition.

He has wrote about a hundred of articles based on his research. Some have been translated into English, French, German, Italian and Japanese. He is the General Editor of the must complete publication on mexican music history, La Música de México [Instituto de Investigaciones Estéticas, IIE / UNAM, México 1984, ca. 2000 p.] He wrote with Jorge Gil Música y Teoría de Grupos Finitos, 3 Variables Booleanas, with an English abstract [IIE UNAM, Mexico 1984]. He has postulated a General Theory of Intervallic Classes, applicable to macro and microintervallic scales of duration and of pitch. In the field of the continuum Estrada has developed new methods of multidimensional graphic description of several parameters of sound or ryhthm. His research on the continuum field will be published in 1998 in France : Ouvrir l’horizon du son : le continuum.

He has been a visiting professor at Stanford, California, San Diego, New Mexico, Musikwissenschaft Institut, Rostock and at Darmstadt.

[edit] Statement

The techniques and theories I have developed are based on mathematics and acoustics ; the more neutral they remain, the better they serve the description of the imaginary : it is my ear---there everything is allowed---that gives birth to my music, which becomes the accurate, almost phonographic representation, of every detail coming from my inner hearing experiences.
