This excerpt is an example of iambic pentameter.
An iambic pentameter is a form of a metrical line in which each line contains five unstressed syllables followed by five stressed syllables. They are usually arranged in an alternating pattern.
Shakespeare followed a new tradition of using blank verse in iambic pentameter. He used this form in his writings as it followed the same tone as that of a human’s heartbeat, a horse’ gallop or with the beat of any music. Iambic pentameter added natural speech and the rhythm of life in his verses.
