First, as the poem proceeds, the speaker experiences a variety of feelings. He feels nostalgic for the past; the music from the piano sends him back to his boyhood, where he was once again a youngster sitting beneath his home's piano. He misses his childhood and feels sorry that it is no longer with him. However, he also feels happy that he has been granted one last glimpse of his favorite thing in the world- the piano- before it leaves for good. Furthermore, as the poem progresses, the speaker becomes more and more obsessed with the piano. At first, he remembers only its pleasant memories: playing songs, dancing, and having fun with his friends. But later on, he starts thinking about the piano in a different way- he begins to miss it even when it is not there anymore. Finally, near the end of the poem, he loses all control over himself and bursts into tears when he realizes that this is the last time he will ever see it. In conclusion, the speaker on the piano feels everything from sad to ecstatic as he watches his favorite thing leave forever.
