Blackbird is about someone who has been living in difficulty but has not lost their spirit and now can live a good life.
Step-by-step explanation:
Blackbird is about a singing bird that has been living in tough conditions but has not lost its spirit.
It has been waiting for a moment to be free of its shackles and now it can sing in freedom.
This song can even be taken to be taken in the racial context of the 60s America where the Blackbird is the African American and they have been ' waiting for this moment to arrive'.
The song is thus written in a reaffirming tone for their future.
