volta

volta, the turn in thought in a sonnet that is often indicated by such initial words as But, Yet, or And yet.

The volta occurs between the octet and sestet in a Petrarchan sonnet and sometimes between the 8th and 9th or between the 12th and 13th lines of a Shakespearean sonnet, as in William Shakespeare’s sonnet number 130:

My mistress’ eyes are nothing like the sun;
Coral is far more red than her lips’ red;
If snow be white, why then her breasts are dun;
If hairs be wires, black wires grow on her head.
I have seen roses damask’d, red and white,
But no such roses see I in her cheeks;
And in some perfumes is there more delight
Than in the breath that from my mistress reeks.
I love to hear her speak, yet well I know
That music hath a far more pleasing sound;
I grant I never saw a goddess go;
My mistress, when she walks, treads on the ground.
And yet, by heaven, I think my love as rare
As any she belied with false compare.
