The writer of the poem "Piano" uses a first person point of view. He is reminiscing about the past when he used to sit under the piano on a cold wintry day. He is moved to tears as he thinks about the past. The speaker longs for the past.
Someone singing and playing the piano has caused the speaker to travel back down the road of his childhood. He is quite emotional in doing so. He can remember days as a child when he sat under the piano as his mother sat at the piano. He is reminiscent of days gone by in which he sat under the piano near his mother's "poised feet." He is filled with such emotion until he breaks down crying, weeping because of the fond memories of childhood. In fact, the speaker admits that he has put aside his manhood to weep like a child over the beautiful memories when he sat under the piano as his mother sat at the piano playing and singing:
The glamour Of childish days is upon me, my manhood is cast Down in the flood of remembrance, I weep like a child for the past.
