What is the impact of the solitary reaper's song on both the woman and the speaker in "The Solitary Reaper"?

The solitary reaper's song is a powerful one. 
Interestingly enough, it might not mean that much to her.  The song is something that
she is singing to complete her work in the field.  Presumably, this is something that
she sings to pass the drudgery of her day.  There is little to indicate that she is
singing a song of transcendent quality to her own state of being in the world.  Rather,
she is simply singing a song to allow her work to pass without as much in way of
boredom.  Yet, this is not how the song is received by the speaker of the poem,
presumably Wordsworth.  He is transfixed by the song.  Unaware of the language in which
it is sung, his mind goes to different suppositions and conjectures on what the song
might mean.  It is here where the readert fully grasps the song's impact on the speaker,
as it allows him to understand the concepts of beauty, grace, and personal meaning it
holds for him.  The song allows the speaker to transcend his current reality, allowing
him to move into what can be or even what should be, as opposed to what is.  For a
moment, the song moves him to a realm where so much is altered that he fully embraces
this particular moment.  A song that might not have held in way of meaning for the one
who sang it is read and felt much differently by another who hears
it.
