In performing arts, a performance generally comprises an event in which a performer, or group of performers, present one or more works of art to an audience. In instrumental music and drama, a performance is typically described as a "play". Typically, the performers participate in rehearsals beforehand to practice the work.
An effective performance is determined by the achieved skills and competency of the performer, also known as the level of skill and knowledge. In 1994, Spencer and McClelland defined competency as "a combination of motives, traits, self-concepts, attitudes, cognitive behavior skills (content knowledge) that helps a performer to differentiate themselves as superior from the average performer". A performance also describes the way in which an actor performs. In a solo capacity, it may also refer to a mime artist, comedian, conjurer, magician, or other entertainer.
