Sonnet 130 displays strong feelings of love, despite the mistress’s lack of physical beauty.
In this sonnet, Shakespeare makes fun of all the exaggerations young men make in comparing their girlfriends to all kinds of natural wonders, such as when Romeo compares Juliet to the sun. Shakespeare takes the opposite approach here, explaining why his girl is not remarkably beautiful.
I love to hear her speak, yet well I know
That music hath a far more pleasing sound;
This makes the poem all the more romantic, because even though he cannot sing the praises of his girl’s beauty, he still loves her. S.he is beautiful to him, in other words, and that is all that matter
