Recap of how we analyzed verses 1-3 of the extract of the poem "Intimations of Immortality from Recollections of Early Childhood”, by W. Wordsworth. 

(Teacher’s corrections & additions in bold type)

Among these three verses we have found a common general idea: it all evokes childhood, its purity and its innocence.
In verses 1 and 2, the triple occurrence of «sing» combined with «joyous song» introduces the poem as happy and carefree. It also gives the poem a lyrical tone. Naturally, this music suggests a celebration is under way. The words "lambs" and "birds" can evoke childhood, innocence, and purity, as well as the rebirth of life and of nature. Such might be the things celebrated by the poet.
"Ye birds" shows a tight connection between the poet and the birds, but also between him and nature as a whole as well. The birds could be friends of the poet, it is a possible personification. The expression "young lambs" is a redundancy: it alludes to the fact the lambs are even younger and echoes the “early childhood” mentioned in the title. The poet wishes to go as far back in time as possible, arguably because the younger we are, the more innocent we are.

"Let the young lamb" evokes freedom, as if barriers and obstacles were destroyed. In parallel, "bound" suggests energy and movement: it alludes to life. No life is really possible without freedom of movement
Verse 3, "As to the tabor's sound" evokes music and celebration. However, the word “as” indicates there is no tabor actually being played: there is no need of music so to a certain degree they are the music or the music is so "intense" that it becomes a feeling. For the poet and for many people, nature is a music that gives them a path to follow. (Camille)
