Chôros No. 10 ("Rasga o Coração") is a work for chorus and orchestra written in 1926 by the Brazilian composer Heitor Villa-Lobos. It is part of a series of fourteen numbered compositions collectively titled Chôros, ranging from solos for guitar and for piano up to works scored for soloist or chorus with orchestra or multiple orchestras, and in duration up to over an hour. Chôros No. 10 is of moderate length, one performance recorded by the composer lasting just under thirteen minutes. History Chôros No. 10 was composed in Rio de Janeiro in 1926, and the score is dedicated to . It was premiered in a concert presented in homage to the President of Brazil, Washington Luís, on 11 November 1926 at the Teatro Lírico in Rio de Janeiro by the Grande Orquestra da Empresa Viggiani, the Coro de artistas brasileiros, and the Deutscher Männerchor, conducted by the composer. This was also Villa-Lobos's farewell performance to Rio de Janeiro. The programme contained an announcement of his imminent departure for Europe. The European premiere took place in Paris on 3 December 1927 at the Salle Gaveau with the Orchestre des Concerts Colonne and L'Art Choral, once again with the composer conducting. The American premiere was given by the Philharmonic-Symphony Orchestra of New York and the Schola Cantorum, conducted by Hugh Ross, on 15 January 1930, at Carnegie Hall in New York. Already within the composer's lifetime the work became the best-known of all the Chôros. In the second half of the work, Villa-Lobos introduces a popular melody, originally a schottische called Yára, written by . In a slower tempo, sung to a poem written by Villa-Lobos's friend and former fellow chorão, , it had become a popular song, "Rasga o coração" (Rend the Heart). It was in this form that Villa-Lobos used both the melody and the words, and he used the song's title as a subtitle for the Chôros, together with an acknowledgement, "D'après la poésie de Catullo Cearence" [sic]. The poet attended the 1926 premiere of Chôros No. 10 in the Teatro Lírico, and was overcome with emotion, embracing the composer in a gesture of gratitude. Unfortunately, in a moment of financial distress, Catulo had sold the rights of all his literary works to a man named Guimarães Martins, who evidently remained ignorant of Villa-Lobos's use of the text for nearly thirty years until by chance, at a demonstration
