The Solitary Reaper’s song was sweeter than the song sung by the nightingale or the cuckoo bird. The poet compares the Solitary Reaper’s song to that of a nightingale or a cuckoo bird. He says that the solitary reaper’s song is as much welcoming to the heart as that of a nightingale’s song to a weary traveller. He says that it induces as much thrill in the atmosphere as that of a cuckoo bird announcing the arrival of the spring time.
