 As the form developed, the purpose of the tornada evolved from a purely stylistic device to include emotional aspects; Levin summarises that "[the tornada] developed in the Italian lyric from a simple concluding formula to a sophisticated projection of the poet's message through the medium of a human character." Whereas tornadas had primarily been an extension of the poet's voice, the innovation of the Dolce Stil Novo movement was to provide them with an autonomous human voice, often in the form of a unique character.
