Recuerdos de la Alhambra (Memories of the Alhambra) is a classical guitar piece composed in 1896 in Granada by Spanish composer and guitarist Francisco Tarrega. It uses the classical guitar tremolo technique often performed by advanced players.The piece showcases the challenging guitar technique known as tremolo, wherein a single melody note is plucked consecutively by the ring, middle and index fingers in such rapid succession that the result is an illusion of one long sustained note. The thumb plays a counter-melody on the bass between melodic attacks. Many who have heard the piece but not seen it performed mistake it for a duet. The A-section of the piece is written in A-minor and the B-section is written in the parallel major (A-major). This gives the song a melancholy feel in the beginning, and then it resolves to an uplifting feel. This device is used in other Spanish guitar songs as well, such as the anonymous Spanish Romance (also known simply as Romance or Spanish Folk Song). - Wikipedia.
