The piece, which lasts around six minutes in performance,[2] was originally written for the piano and set in the key of G minor.
The origin of the presumably misattributed name was that in fact Albéniz did compose a piano work actually called (by himself) 'Asturias', which made part of a set of pieces of folk music from all over Spain for the then Queen of Spain, but this piece is lost, and maybe its name was passed on the now so called one.
Albéniz's biographer, Walter Aaron Clark, describes the piece as "pure Andalusian flamenco".
[5] The "marcato"/"staccato" markings suggest both guitar sounds and the footwork of a flamenco dancer.
Clark states that it is written in typical Albéniz form as it is "presented monophonically but doubled at the fifteenth for more fullness of sound.
Iron Maiden quotes Asturias in their songs Mother Russia and To Tame A Land.
