This music is the Nocturne Op. 9 No. 2 in E-flat major by Frederic Chopin, as arranged by Francisco Tárrega for Guitar solo transposing the music to E major which is a more comfortable key for guitar. A Nocturne was originally a piece of music to be played in the evening, a similar concept to a Serenade, but it came to mean simply a stand-alone piece usually for piano and with a rich Romantic melody.
