What point of view does the poet use in "Piano" (and how does this show the general purpose)?

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.
