 In classical music, two especially popular birds are the nightingale and the cuckoo.The nightingale's song has been used by composers including Handel, who quoted it in the aria "Sweet bird" in "L'Allegro, il Penseroso ed il Moderato", in the "Nightingale chorus" in "Solomon", and in his Organ Concerto "No.13", known as "The Cuckoo and the Nightingale".
