Considering the title the intelligent reader could understand it is a sonnet by William Shakespeare.

In the title the poet uses a alliteration of the consonant 'm', therefore the fist word is the possesive pronoun 'my'. The speaker wants to show his lover (Mistress) in a unusual way comparing her to a lot of things.

Considering the layout the poet shows that the sonnet follow the Elizabeth model and not the Petrarchan one. The text is organised into four stanza: three quatrains and a final couplet.

Usually, in the quatrains the poet presents a problem and it is solved in the final couplet.

The first stanza starts with a statement by the speaker. He introduces his woman. She is very powerful, but the poet reduces his power. He compares his mistress to the nature, but he doesn't follow the love courtly model. Indeed she is compared to the nature, but he tells that the nature is more beautiful than his mistress.

In the second stanza the poet repets the same comparison, indeed she is described in a unusual way; she is the loser because her cheeks are less beautiful than damasked roses and also adds that parfumes are much better than hers.

The third quatrain seems to introduce something different because the poet introduce something totally different from courtly convention. He states that he loves his mistress all the same even if she does not conform to the traditional beauty of the poetry. He says that he likes listening to his lover speaks even if perfectly however that music is much more pleasure to listen to.

In the end of the third stanza the speaking voice confesses is never seen a goodness but he notes that his lady treads on the ground.

The last stanza that generally illustreted the difficoult aspect of the speaker are here meant to anticipate the conclusion that is espressed in the rhyme couplet so that they also respond to a climatic effect: the one of the rhyme couplet where the poet reveats that he loves his woman, even if she is not the perfecty presentation of the conventional lady of courtly convention.

Shakespeare's choise is meant to be the parody of the convention of cortly love poetry.
