Isaac Manuel Francisco Albéniz y Pascual (Spanish pronunciation: [iˈsak alˈβeniθ]; 29 May 1860 – 18 May 1909) was a Spanish pianist and composer best known for his piano works based on folk music idioms. Transcriptions of many of his pieces, such as Asturias (Leyenda), Granada, Sevilla, Cadiz, Córdoba, Cataluña, and the Tango in D, are important pieces for classical guitar, though he never composed for the guitar. The personal papers of Albéniz are preserved, among other institutions, in the Biblioteca de Catalunya.
Born in Camprodon, province of Girona in Spain, to Ángel Albéniz (a customs official) and his wife, Dolors Pascual, Albéniz was a child prodigy who first performed at the age of four. At age seven, he passed the entrance examination for piano at the Conservatoire de Paris, but he was refused admission because he was believed to be too young. By the time he had reached 12, he had made many attempts to run away from home.
His concert career began at the age of nine when his father toured both Isaac and his sister, Clementina, throughout northern Spain. A popular myth is that at the age of twelve Albéniz stowed away in a ship bound for Buenos Aires. He then found himself in Cuba, then to the United States, giving concerts in New York and San Francisco and then travelled to Liverpool, London and Leipzig, Germany. By age 15, he had already given concerts worldwide. This over-dramatized story is not entirely false. Albéniz did travel the world as a performer; however, he was accompanied by his father, who as a customs agent was required to travel frequently. This can be attested by comparing Isaac's concert dates with his father's travel itinerary.
