type of poetry written in the form of a speech of an individual character
Dramatic monologue is a type of poetry written in the form of a speech of an individual character. M.H. Abrams notes the following three features of the dramatic monologue as it applies to poetry:
The single person, who is patently not the poet, utters the speech that makes up the whole of the poem, in a specific situation at a critical moment […].
This person addresses and interacts with one or more other people; but we know of the auditors' presence, and what they say and do, only from clues in the discourse of the single speaker.
The main principle controlling the poet's choice and formulation of what the lyric speaker says is to reveal to the reader, in a way that enhances its interest, the speaker's temperament and character.
