"Blackbird"

The "Blackbird" in this song represents or symbolizes someone being born into a bad situation. The song then tells the story of how this blackbird got out of the bad situation. This is demonstrated by the use of symbols such as "broken wings" and "sunken eyes." These things represent bad situations. "Learn to fly" as well as "learn to see" symbolize making the best out of those porous situations.  The single effect of this song is to inspire people to better their lives not matter how bleak they seem.
