This is the air „Ombra May fù“ from the opera „Xerxes“ (Serse) by Handel, a love song of the king of Persia, Xerxes, to a tree. It ranks among Handels most well-known melodies and often simply is called as „Handels Largo“. To this version for double bass and piano (or harp) two piano voices are attached: One in A major for the accompaniment of the double bass in solo tune and one in G major for the accompaniment of the double bass in orchestra tune.
