Acting in the context of Audition

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.

Voice acting is the art of performing a character or providing information to an audience with one's voice. Performers are often called voice actors/actresses in addition to other names. Examples of voice work include animated, off-stage, off-screen, or non-visible characters in various works such as films, dubbed foreign films, television shows, video games, animation, documentaries, commercials, audiobooks, radio dramas and comedies, amusement rides, theater productions, puppet shows, and audio games.

The role of a voice actor may involve singing, most often when playing a fictional character, although a separate performer is sometimes enlisted as the character's singing voice. A voice actor may also simultaneously undertake motion-capture acting. Non-fictional voice acting is heard through pre-recorded and automated announcements that are a part of everyday modern life in areas such as stores, elevators, waiting rooms, and public transport. Voice acting is recognized as a specialized dramatic profession in the United Kingdom, primarily due to BBC Radio's long and storied history of producing radio dramas.

Motion-capture acting, also called performance-capture acting and often abbreviated as mo-cap or P-cap, is a type of acting in which an actor wears markers or sensors on a skintight bodysuit or directly on the skin. Several cameras from different angles record the actor's movements simultaneously, recording the three-dimensional position of the sensors without recording the rest of the actor. Sampling is done many times each second, aided by advances in computer technology. The resulting database of 3D points permits a filmmaker or video game creator to create a digital character and place them in an entirely new setting.

The first virtual actor animated by motion-capture was produced in 1993 by Didier Pourcel and his team at Gribouille. It involved "cloning" the body and face of French comedian Richard Bohringer, and then animating it with still-nascent motion-capture tools.

An Actor Prepares (Russian: Рабо́та актёра над собо́й, romanized: Rabóta aktyora nad sobóy, IPA: [rɐˈbotə ɐkˈtʲɵrə nət sɐˈboj]) is the first of Konstantin Stanislavski's books on acting, followed by Building a Character and Creating a Role. Stanislavski intended to publish the contents of An Actor Prepares and Building a Character as a single volume, and in the Russian language. However, An Actor Prepares was first published as a single volume in English, and World War II delayed the publication of Building a Character for more than ten years.

In acting, a bit part is a role in which there is direct interaction with the principal actors and no more than five lines of dialogue, often referred to as a five-or-less or under-five in the United States, or under sixes in British television, or a walk-on part with no dialogue.

A bit part is a credited higher billing than that of an extra and lower than that of a supporting actor. An actor who regularly performs in bit roles, either as a hobby or to earn a living, is referred to as a bit player, which is also a term to describe an aspiring actor who has not yet broken into supporting or leading roles.

Role-playing or roleplaying is the changing of one's behaviour to assume a role, either unconsciously to fill a social role, or consciously to act out an adopted role. While the Oxford English Dictionary offers a definition of role-playing as "the changing of one's behaviour to fulfill a social role", in the field of psychology, the term is used more loosely in four senses:

• To refer to the playing of roles generally such as in a theatre, or educational setting;
• To refer to taking a role of a character or person and acting it out with a partner taking someone else's role, often involving different genres of practice;
• To refer to a wide range of games including role-playing video game (RPG), play-by-mail games and more;
• To refer specifically to role-playing games.
