Sonnet
It was, however, Sir Philip Sidney's sequence "Astrophel and Stella" (1591) that started the English vogue for sonnet sequences. The next two decades saw sonnet sequences by William Shakespeare, Edmund Spenser, Michael Drayton, Samuel Daniel, Fulke Greville, William Drummond of Hawthornden, and many others. These sonnets were all essentially inspired by the Petrarchan tradition, and generally treat of the poet's love for some woman, with the exception of Shakespeare's sequence of 154 sonnets. The form is often named after Shakespeare, not because he was the first to write in this form but because he became its most famous practitioner. The form consists of fourteen lines structured as three quatrains and a couplet. The third quatrain generally introduces an unexpected sharp thematic or imagistic "turn", the volta. In Shakespeare's sonnets, however, the volta usually comes in the couplet, and usually summarizes the theme of the poem or introduces a fresh new look at the theme. With only a rare exception (for example, Shakespeare's Sonnet 145 in iambic tetrameter), the meter is iambic pentameter.
Sonnet 110
The sonnet is a confession of the poets committed sins and promiscuity, which quickly escalates to his confession of love to the young man. With Shakespeare's heavy use of double meanings to words have scholars perplexed as to whether the sonnet is about Shakespeare's career as an actor or a confession of love to the young man. The sonnet is written in traditional Shakespearean sonnet form consisting of 14 lines with Iambic Pentameter and ending with a couplet.
