Carrillo organized and conducted the Beethoven Symphony Orchestra (1909) and the Beethoven String Quartet (1910). He published Discursos sobre la música (Discourses on music, 1913) and Pláticas musicales (Musical talks, 1914 and 1922). In 1910 he performed for the first time his Canto a la Bandera (Song to the Flag, with lyrics by Rafael López), which has been since an official song to the Mexican Patriot Flag. In 1911 Carrillo was official delegate to both the Musical Congress of Rome and the Musical Congress of London.
