Acting in the context of "Mimesis"

Opera is a form of Western theatre in which music is a fundamental component and dramatic roles are taken by singers. Such a "work" (the literal translation of the Italian word "opera") is typically a collaboration between a composer and a librettist and incorporates a number of the performing arts, such as acting, scenery, costume, and sometimes dance or ballet. The performance is typically given in an opera house, accompanied by an orchestra or smaller musical ensemble, which since the early 19th century has been led by a conductor. Although musical theatre is closely related to opera, the two are considered to be distinct from one another.

Opera is a key part of Western classical music, and Italian tradition in particular. Originally understood as an entirely sung piece, in contrast to a play with songs, opera has come to include numerous genres, including some that include spoken dialogue such as Singspiel and Opéra comique. In traditional number opera, singers employ two styles of singing: recitative, a speech-inflected style, and self-contained arias. The 19th century saw the rise of the continuous music drama.

Real life is a phrase used originally in literature to distinguish between the real world and fictional, virtual or idealized worlds, and in acting to distinguish between actors and the characters they portray. It has become a popular term on the Internet to describe events, people, activities, and interactions occurring offline; or otherwise not primarily through the medium of the Internet. It is also used as a metaphor to distinguish life in a vocational setting as opposed to an academic one, or adulthood and the adult world as opposed to childhood or adolescence.

A backstory, background story, background, or legend is a set of events invented for a plot, preceding and leading up to that plot. In acting, it is the history of the character before the drama begins, and is created during the actor's preparation.

A model is a person with a role either to display commercial products (notably fashion clothing in fashion shows) or to serve as an artist's model.

Modelling ("modeling" in American English) entails using one's body to represent someone else's body or someone's artistic imagination of a body. For example, a woman modelling for shoes uses her foot to model the potential customers' feet. Modelling thus is different from posing for portrait photography, portrait painting, and distinct from other types of public performance, such as acting or dancing. Personal opinions are normally not expressed, and a model's reputation and image are considered critical.

A vocal warm-up is a series of exercises meant to prepare the voice for singing, acting, or other use.

Vocal warm-ups are essential exercises for singers to enhance vocal performance and reduce the sense of effort required for singing. Research demonstrates that engaging in vocal warm-ups can temporarily elevate vocal effort, which normalizes after a short rest, enhancing vocal readiness for performance.

The "art of representation" (Russian: представление, romanized: predstavlenie) is a critical term used by the seminal Russian theatre practitioner Konstantin Stanislavski to describe a method of acting. It comes from his acting manual An Actor Prepares (1936). Stanislavski defines his own approach to acting as "experiencing the role" and contrasts it with the "art of representation". It is on the basis of this formulation that the American Method acting teacher Uta Hagen defines her recommended Stanislavskian approach as 'presentational' acting, as opposed to 'representational' acting. This use, however, directly contradicts mainstream critical use of these terms. Despite the distinction, Stanislavskian theatre, in which actors 'experience' their roles, remains 'representational' in the broader critical sense.
