El Cóndor Pasa (pronounced: [el ˈkondoɾ ˈpasa], Spanish for "The Condor passes") is an orchestral musical piece from the zarzuela El Cóndor Pasa by the Peruvian composer Daniel Alomía Robles, written in 1913 and based on traditional Andean music, specifically folk music from Peru and Bolivia. Since then, it has been estimated that around the world, more than 4000 versions of the melody have been produced, along with 300 sets of lyrics. In 2004, Peru declared this song as part of the national cultural heritage. This song is now considered the second national anthem of Peru.
