Title Sequence) that briefly explains the series's premise. These are typically vague and prosaic, sometimes falling into Fauxlosophic Narration, and are delivered either by a lead character, or by a Narrator. The content is similar to the expository type of theme tune.
Usually, these monologues do not change much over the course of a series, though some shows do revise them from season to season. The whole concept is probably an artifact from the days of radio, when, lacking title graphics, shows needed a memorable speech at the beginning to identify themselves to listeners.
Sometimes, a show's first episode will start with a "Cold Opening", another name for The Teaser, and in every episode thereafter the Opening Narration will take its place. This will only happen if said episode is a Welcome Episode or an Everyone Meets Everyone Premiere.
Also becoming increasingly common in Animes is to use a clip montage of the respective episode with the show's main character(s) explaining the plot of the episode.
Also known as a prologue or a "saga sell", an opening narration is often used to 'set the scene' at the opening of a show that might be confusing for first-time viewers (Joss Whedon famously used one for Buffy the Vampire Slayer, as the show was initially a mid-season replacement and new viewers might not 'get' the concept).
- Erika and the Princes in Distress : The first episode of the audio adaptation opens with one, which briefly describes the world in which the story takes place.
Narrator: Imagine a world... A world in which genders as we know them would be reversed, swapped around. A world in which women would be the dominant gender, and in which men would be a little more, let's say... weak. This story first starts in the Kingdom of Brutes. Ah, here! There seems to be a bit of action in the castle's courtyard.

- The Dragon Age: Inquisition series Twice Upon an Age is littered with notes from Varric Tethras, who is credited as the editor of the series.

- From the second Tantei Team KZ Jiken Note novel (The Ripped Page Knows) on, the first chapter (titled Aya Tachibana's Monologue from the third novel on) of every novel would include a brief summary of the premise, including what Soccer Team KZ is, how she get to know them, then followed by some materials that are different in different novels. The spinoff series Yousei Team G Jiken Note is similar, with the opening chapter called Tennen Character.
