What is the Meaning & Definition of libretto

We define libretto that written work which is used as a guide for the actors in a film or play. The libretto is normally composed of dialogue that these actors must repeat and interpret and also indications on positions in the space in which it acts (sitting on a Chair), movements (enters the room) or information about the scenario, environment and others. These indications which do not form part of the dialogue are not read or interpret, simply serve to facilitate the creation of the scene. The libretti emerged historically with the first theatrical performances, those that have arisen in the ancient Greece (although for some, they already exist since Egyptian civilization). The scripts, or these forms primitive what we currently know as libretti, were written to guide stakeholders in dialogue and were probably much simpler than they are the scripts today. The existence of scripts can be found both in the middle ages and, subsequently, in the modern era in which William Shakespeare was without any doubt one of the leading representatives of scripts for plays. The scripts have a form or structure more or less similar in all cases. They are divided into acts or scenes in which a set of acts or interrelated dialogues happen. Each scene clarifies, as far as possible, the location of each character, the environment in which are and other data to then go to the dialogue between the various characters of the play itself. This dialogue is written by specifying the name of each person who speaks or interacts with the others. In the scripts both the words and sounds and even the silences should be marked to so that the actors can know when to talk and when to remain silent.
