Monologue  

... I found
A thing to do, and all her hair
In one long yellow string I wound
Three times her little throat around,
And strangled her.

--Porphyria's Lover (1836) by Robert Browning

"Where the character delivering the monologue is alone on stage it may also be described as a 'soliloquy'. Writers such as Shakespeare used the soliloquy to great effect in order to express some of the personal thoughts and emotions of characters without specifically resorting to third-person narration.

It is a dramatic convention that soliloquies and asides cannot be heard or noticed by the other characters, even if they are delivered in their plain view.

A written monologue may contain stage directions for the performer, and might be preceded by information about the monologue's setting. (For example, Samuel Beckett's monologue, Krapp's Last Tape).

The monologue was a significant feature of French classical drama; the monologues of Racine have been highly prized by French actresses, including Rachel and Sarah Bernhardt.

The dramatic monologue is a poetic form not to be confused with the monologue in drama. It was brought to a high standard by Robert Browning. The form is such wherein the poet writes from a speaker's point of view in the form of an address to a listener who does not respond in the poem. The speaker in the poem generally talks about a subject, but inadvertently reveals something about their character. It gives the poet an opportunity to present his subject in direct 'conversation' with the reader (e.g. Browning's Porphyria's Lover) or places the reader as a 'character' to whom the monologist speaks (e.g. the same poet's Mr. Sludge the Medium or My Last Duchess). Such poetry combines the dramatic impact of the stage monologue with the potential of more elaborate and suggestive use of language; on the printed page, where the words can be re-read and pondered, there is the potential to evoke more complex layers of intent and meaning.

The term "monologue" is also applied to a form of popular narrative verse, sometimes comic, often dramatic or sentimental, that was performed in music halls or in domestic entertainments in the late nineteenth and early twentieth century. Famous examples include Idylls of the King, The Green Eye of the Yellow God and Christmas Day in the Workhouse."
