Structure of the poem "Ode to the West Wind"

Shelley’s form or structure in this poem is one of his own invention. He uses elements of the sonnet in combination with the Italian three-line rhyme scheme known as terza rima.

Shelley's poem also reflects incomprehensible movement of the wind. He makes use of the run on sentences your teacher would deem grammatically incorrect in his depiction of the breeze. He also uses alliteration, rhyme, and assonance, which compliments the poem's theme of regeneration or what might be better understood as the cycle of life.
