Writings on the composers and his works

Juan Orrego-Salas is an important figure in the history of contemporary Latin American music. He has contributed as a musician to diverse areas of music, especially as a composer and musicologist, In addition he has performed duties in the scholarly and administrative fields, including those of being one of  the founders of the Escuela Moderna de Musica, the creator and first director of the Department of Music of the Catholic University, in Chile, as of  the Latin American Music Center, of Indiana University in United States..

Orrego-Salas was born in Santiago, Chile, in January 18, 1919. He initiated his basic general education and  training as a musician in his native city, later studying and obtaining his diploma in architecture, in 1943. By that time he had completed his undergraduate work in composition, with P.Humberto Allende and Domingo Santa Cruz, was teaching History and Literature of Music at the State Universidad of Chile and conducting the Catholic University Choir, which he had established in 1938. In 1944 he abandoned his work as an architect to dedicate his full time to music.

This period in his life started with a two year residence in the United States, first as a Rockefeller Foundation grantee, and following, as a Guggenheim Foundation Fellow. He then studied composition with Aaron Copland in Tanglewood, and in the universities of Virginia and Princeton with Randall Thompson, as well as musicology with Paul Henry Lang and Georg Herzog in Columbia University.

In 1947, he returned to his professorial, - now as a full professor of the Music Faculty,-  at the University of Chile and  choral conductor at the Catholic University. In 1949 he traveled to Europe, as a guest of the British Council,  the French and Italian Governments. In this tour he conducted the world premiere performance of his Canciones Castellanas, Op. 20, selected for the XXIII Festival of the International Society of Contemporary Music (ISCM), held in Palermo and Taormina, Sicily. At his return from this trip he accepted the editorship of the Revista Musical Chilena and in 1950 he added to his duties, those of music critic of El Mercurio, Chile's leading morning paper. An uninterrupted dedication to composition resulted in continuous performances of his works in Chile and abroad, and in his receiving many commissions to write compositions for orchestra and a variety of chamber ensembles..

In 1953, the Universidad de Chile, conferred upon him the title of Profesor Extraordinario (Distinguished Professor) of composition, and the following year he returned to United States, and spent a year composing in New York, making use of a second Guggenheim Fellowship. This time he returned to his home country  to become the director of the Instituto de Extensión Musical, the organization under whose leadership the Orquesta Sinfonica de Chile, the National Ballet, and a number of choral and chamber ensembles operated. After two years in this position he resigned to become the founder and first director of the Departamento de Música (now Instituto de Musica) of the Catholic University in Santiago. He remained in this position until 1961 and after twenty year teaching as a member of the Music Faculty of the Universidad de Chile, he was granted a partial retirement, when he returned to the United States, this time to establish and direct the Latin American Music Center and teach composition at the School of Music of Indiana University, in Bloomington. After serving twenty seven years as such and from 1975 to 1980 as Chairman of the Composition Department, he retired in 1987 as “Professor Emeritus”.
As a composer he was in four occasions the winner of prizes in the Festivaesl de Musica Chilena (1948, 1950, 1952, 1998) and twice recipient of the Olga Cohen Prize (1956, 1958), in his home country, was granted the title of Doctor “Honoris Causa” by the Universidad Catolica, in1971 and named Corresponding Member of the Chilean Academy of Fine Arts  and Distinguish Professor by the Pontifical Catholic University of Valparaiso, Chile (1999).

In 1992 he received the “Premio Nacional” , the highest recognition conferred by the Chilean Government to its artist, writers, scientists and historians. In the international space the Organization of American  States in Washington D.C.  granted him in 1988 the"Gabriela Mistral Interamerican Cultural Prize." One of his frequent  returns to Chile was in November 2005 to attend the presentation of his bookEncuentros, visions y repasos”, partly his memoirs and partly a chronicle on his thoughts and ideas on music in general and reflections on his own work as a creator. He then attended a concert of two major works of his by the Orquesta Sinfónica de Chile conducted by his son Juan Felipe Orrego.

Orrego-Salas has received commissions from the Koussevitzky, Coolidge, Kindler, Wechsler, Riley, Stieren foundations, from the Lousville Orchestra, the National Symphony of Washington D.C., from the universities of Cornell, Miami, Trinity, Santa María, from the National Endowment for the Arts, the Inter American Music Council, in United States, from the Frei Foundation and the Colegio de Arquitectos in Chile, and from numerous chamber music ensembles, soloists and individuals..

As a teacher and lecturer he has appeared in many universities, colleges and cultural institutes, in Chile, United States, Argentina, Peru, Uruguay, Brazil, Colombia, Venezuela, Mexico, Great Britain, Spain, France, Italy, Russia and Yugoslavia., and participated in several international meetings.
