If you take an interest in a dictionary or other source, you will find out that tetralogy is a work of literature, music, cinematography, consisting of four interconnected sequential parts (Greek tetra - “four”, logos - “word, story, narrative”). Most often, the components of this work are issued or published independently of each other.
To make it more clear, just try to recall some of these works from memory.
Tetralogy in the cinema
The most famous tetralogy is films about the adventures of Indiana Jones. There was an exciting screen action, so it is predictably left in the memory of several generations.
The next example is the tetralogy that the older generations perfectly remember, “Resident” about the fate of intelligence officer Mikhail Tulev in four parts: “Resident's mistake” , “ Resident's fate” , “ Resident's return” and “ End of resident operation.” The films were characterized by logical development actions in a single key and with one main character.
For those younger, tetralogy is the Shrek or Toy Story series.
If you reflect and remember all your favorite TV shows from early childhood, you can list for a long time. Great theme for playing with friends, for example.
What is tetralogy in the literature
Let us now cite literary examples. The most popular tetralogy is a vampire story called Twilight by Stephanie Meyer. It was originally released in several volumes, becoming the undisputed bestseller, and only then was it filmed.
Four sequential books describing the adventures of Lemuel Gulliver can also be added to tetralogy. The name of the work itself mentions that it consists of four parts - according to the number of trips of the protagonist of the book. As it should be in the works related to tetralogy, there is a single plan of the author and a developing storyline.
It can also be attributed to the tetralogy of the work of Victor Pelevin (Chapaev and the Void, Generation P, Numbers, The Werewolf Sacred Book), where the author’s unified plan and storyline are traced.
Tetralogy in music
In the musical sphere, works consisting of several parts are also called "cyclical".
The most striking example of musical tetralogy is the work "The Ring of the Nibelungs", written by Richard Wagner from 1848 to 1874.
Also, such fugitives, preludes can be attributed to such cyclical works.
What else can be attributed to the definition of tetralogy? The fact that each of the four parts is an integral part of the main storyline, but at the same time an independent integral piece.
