The "Canción Nacional" (Spanish pronunciation: [kanˈsjon nasjoˈnal] kahn-SYOHN nah-syoh-NAHL; "National Song"), also known by its incipit Puro, Chile, es tu cielo azulado (Spanish pronunciation: [ˈpuɾo ˈtʃile ˈes tu ˈsjelo asuˈlaðo] POO-roh CHEE-leh ES too SYEH-loh ah-soo-LAH-doh; "How pure, Chile, is thy blue sky"), is the national anthem of Chile. It was composed by Ramón Carnicer and first adopted in 1828. Later, the Chilean government wanted words for the song, so eventually, a poet by the name of Eusibio Lillo wrote the lyrics to the anthem in September 1847.
