What is Dramatic Monologue ? Please use your own words to analyze the literary term.

By dramatic monologue it is meant that a poet chooses a dramatic moment or a crisis, in which his characters are made to talk about their lives, and about their minds and hearts. In “listening” to those one-sided talks, readers can form their own opinions and judgments about the speaker's personality and about what has really happened. Robert Browning brought this poetic form to its maturity and perfection and his “My Last Duchess” is one of the best-known dramatic monologues.
