He was also the composer of the anthems of the Partido Radical (Radical Party), the Juventudes Comunistas (Communist Youth), and the Central Unica de Trabajadores. He also turned Salvador Allende"s political plan, embodied in the texts of Julio Rojas, into an album called 'Canto al programa'.

Ortega composed some of the seminal works of the movement known as the Nueva Canción Chilena (New Chilean Song), a fusion of rhythms and styles with a social conscience. In his work, one can find poems, cantatas, operas, songs, and soundtracks. Among his most famous works are the songs 'El monte y el río' (The Mountain and the River), lyrics by Nicolás Guillén, and 'Les deux mere' (The Two Seas), and a trilogy about the French Revolution.

Ortega composed a fair number of songs for use in the theater, one of his last works being the opera of fellow communist Pablo Neruda's epic poem Fulgor y muerte de Joaquín Murieta (Brilliance and Death of Joaquín Murieta). He also worked on a musical version of Neruda's Canto general which Gustavo Becerro, which was staged in 1970. In 1978, Ortega wrote a cantata of Neruda"s 'Bernardo O'Higgins Riquelme, 1810.

In 1969, Ortega became a professor of composition in the Conservatory. A year later, in 1970, he began to direct the University's TV station, Channel 9, which he continued until 1973. At the end of 1973, after the September 11 coup, Ortega fled to France, where he resided until his death. He was given permission to return to Chile in 1983, and did so several times.
