Isaac Manuel Francisco Albéniz y Pascual (Spanish pronunciation ) ( Born 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.
