How can sound devices affect a poem?

Poison Tree by William Blake

I was angry with my friend; 

I told my wrath, my wrath did end. 

I was angry with my foe: 

I told it not, my wrath did grow. 

And I waterd it in fears, 

Night & morning with my tears: 

And I sunned it with smiles, 

And with soft deceitful wiles. 

And it grew both day and night. 

Till it bore an apple bright. 

And my foe beheld it shine, 

And he knew that it was mine. 

And into my garden stole, 

When the night had veild the pole; 

In the morning glad I see; 

My foe outstretched beneath the tree.

    

Many poems use forms of rhyming or other sound devices to create meaning or depth in the poem. In Poison tree by William Blake he uses a couplet pattern of rhyming in the poem. For me personally I think this really creates meaning because it makes you stop and think about what's going on because you think about the rhymes. I think it adds to the way that the reader could read and interpret the poem. For instance this poem has a couplet pattern which could make the rhythm you read it different.

A lot of poems written in the Romanticism Era have reference to nature, as well as this one in the end. Romanticism originated during the end of the 18th century, I think that this really showed through the poem and the way it’s written.
