⭐ Core Definition: Performer

The performing arts are arts such as music, dance, and drama which are performed for an audience. They are different from the visual arts, which involve the use of paint, canvas or various materials to create physical or static art objects. Performing arts include a range of disciplines which are performed in front of a live audience, including theatre, music, and dance.

Theatre, music, gymnastics, object manipulation, and other kinds of performances are present in all human cultures. The history of music and dance date to pre-historic times whereas circus skills date to at least Ancient Egypt. Many performing arts are performed professionally. Performance can be in purpose-built buildings, such as theatres and opera houses; on open air stages at festivals; on stages in tents, as in circuses; or on the street.

👉 Performer in the context of Extra (acting)

A background actor or extra is a performer in a film, television show, stage, musical, opera, or ballet production who appears in a nonspeaking or nonsinging (silent) capacity, usually in the background (for example, in an audience or busy street scene). War films and epic films often employ background actors in large numbers: some films have featured hundreds or even thousands of paid background actors as cast members (hence the term "cast of thousands"). Likewise, grand opera can involve many background actors appearing in spectacular productions.

On a film or TV set, background actors are usually referred to as "supporting artists", "junior artists", "atmosphere", "background talent", "background performers", "background artists", "background cast members", "talent", "background friends", or simply "background", while the term "extra" is rarely used and is often considered derogatory. In a stage production, background actors are commonly referred to as "supernumeraries". A more archaic theatre term is "sword carriers". In opera and ballet, they are called either "extras" or "supers".

Performer in the context of Varied practice

In the study of learning and memory, varied practice (also known as variable practice or mixed practice) refers to the use of a training schedule that includes frequent changes of task so that the performer is constantly confronting novel instantiations of the to-be-learned information.

The varied practice approach focuses on the distribution of practice in time, the organization of activities to be practiced (blocked vs. random), and the interleaving of information or content to highlight distinctions that facilitate learning. For example, a varied practice approach to learning to shoot a basketball might involve a sequence of ten mid-range jump shots, followed by ten layups, followed by ten free throws, followed by ten three-pointers, with the entire cycle repeating ten times. This contrasts with traditional approaches in which the learner is encouraged to focus on mastering a particular aspect or subset of the relevant information before moving on to new problems (e.g., focusing on free throws before moving to three-pointers). With varied practice, the learner is exposed to multiple versions of the problem even early in training.
