Daniel Alomía Robles was a Peruvian composer and ethnomusicologist born in Huánuco, Peru, in 1871. He is best known for composing the song El Cóndor Pasa in 1913, based on Andean folk songs, which became popular worldwide when it was used by Simon and Garfunkel as their music for El Cóndor Pasa (If I Could), with different lyrics. Alomía Robles traveled throughout Peru compiling the stories and myths of the folk music of the Amazon jungle regions and the mountains of the Andes, and he also traveled to Bolivia and Ecuador. In 1910, he discovered that the musical structure of Andean music involved a Pentatonic scale. Alomía Robles was a pioneer in collecting music that otherwise would have disappeared. He died in 1942.
