Art as a figurative interpretation of reality exists in different forms and forms. A distinctive feature of each, giving out its specificity, is the material that the creator uses to create artistic images. For a musician this is a sound, for a writer - a word. For an actor such material is an action. In the broadest sense, action is a volitional act aimed at achieving a specific goal. Actor or stage action is one of the main expressive means, a single psychophysical process of achieving the goal in the struggle against the proposed circumstances of the small circle, expressed in some way in time and space. Through him, the artist embodies his stage image, reveals the goals, the inner world of the character and the ideological design of the work.
In simple words, the stage action is the ability to see, hear, move, think and speak in the given circumstances to realize the image. This definition seems more understandable, but at the same time it refers us to the conclusion about the complexity of the structure of the constituent parts. In fact, the action implies their coherent work and is a synthesis of scenic movement, attention, emotional memory, actor's speech.
Researchers of the Stanislavsky system pay attention to the fact that its essence is precisely expressed in the stage action. On it, the teacher built his teaching, because everything is connected with the action. Its nature is such that the process of creativity takes place on the verge of reality and art. This is called the "pendulum phenomenon": the actor swings from the truth of the life event to the conventionality of the theater. He is forced to work "on the brink" - between truth and fiction, accuracy and improvisation, reincarnation and the desire for self-expression, similarity and dissimilarity in different roles. This is the essence of the theater.
