An example of a monologue is the well known speech from Shakespeare's Macbeth that begins, "To be or not to be..."

In the theater, the definition of a monologue is normally either

1. an extended section of script in which one character speaks or lectures without others interacting, or
2. a speech, varying in size, that an actor recites at an audition so that the auditioners can get an idea of their talent, usually taken from 1 (above).

2. The form or style of such speeches.

A monologue is one person speaking to the exclusion of others. It can be a comedian or actor on stage alone. Or, it can be a person monopolizing the conversation by talking on and on preventing others from speaking.
