Iambic pentameter is a poetic device that has been used by
famous writers for centuries.

Iambic Pentameter Definition

In a line of poetry, an iamb is a foot or beat consisting of
an unstressed syllable followed by a stressed syllable, or a short syllable
followed by a long syllable, according to FreeDictionary.com. An example is the
word comPLETE. Interestingly enough, the iamb sounds a little like a heartbeat.

FreeDictionary.com defines pentameter as a line of verse
consisting of five metrical feet. When put together, iambic pentameter may be
defined as a line of verse consisting of five metrical feet where each foot
consists of an unstressed syllable and a stressed syllable.

Examples

William Shakespeare was famous for using iambic pentameter
in his sonnets. Here's one example from his Sonnet 18:

Shall I compare thee to a summer's day?

Thou art more lovely and more temperate.

Rough winds do shake the darling buds of May,

And summer's lease hath all too short a date.

Sometime too hot the eye of heaven shines,

And often is his gold complexion dimmed;

And every fair from fair sometime declines,

By chance, or nature's changing course, untrimmed;

But thy eternal summer shall not fade,

Nor lose possession of that fair thou ow'st,

Nor shall death brag thou wand'rest in his shade,

When in eternal lines to Time thou grow'st.

So long as men can breathe, or eyes can see,

So long lives this, and this gives life to thee.

Notice that the pattern of stressed and unstressed syllables
in bold does not necessarily correspond to the number of words used. One must
always listen for that heartbeat pattern 'du-DUH, du-DUH.' The unstressed
syllable may start in one word and the stressed syllable may follow in a
completely different word.

Also, we don't read lines of iambic pentameter in an
unstressed/stressed pattern of vocal inflection. The line would sound very
different if we read it that way, almost like an exaggerated Count Dracula
saying, 'I've COME to DRINK your BLOOD.' Try reading the first line of Sonnet
18 with an exaggerated sense of unstressed and stressed syllables. It would
look and sound like this: Shall I comPARE thee TO a SUMmer's DAY?

That is not what Shakespeare intended, as is readily evident.
It sounds funny when it is read that way. The genius is in the crafting of such
lines, using this poetic device so that they flow almost unsuspectingly along
with iambic pentameter. The reader is hardly aware of the iambic pentameter but
is absorbed in the meaning of the lines, which is as it should be.
