Applause (Latin , to strike upon, clap) is primarily a form of ovation or praise expressed by the act of clapping, or striking the palms of the hands together, in order to create noise. Audiences usually applaud after a performance, such as a musical concert, speech, or play, as a sign of enjoyment and approval.
History
The age of the custom of applauding is uncertain, but it is widespread among human cultures. The variety of its forms is limited only by the capacity for devising means of making a noise (e.g., stomping of feet or rapping of fists or hands on a table). Within each culture, however, it is usually subject to conventions.
The ancient Romans had set rituals at public performances to express degrees of approval: snapping the finger and thumb, clapping with the flat or hollow palm, and waving the flap of the toga. Emperor Aurelian substituted the waving of napkins () that he had distributed to the Roman people for the toga flapping. In Roman theatre, at the close of the play, the chief actor called out "" (farewell and applaud), and the audience, guided by an unofficial choregos, chanted their approval antiphonally. This was often organized and paid for.
Similarly, a claque (French for "slapping") was an organized body of professional applauders in French theatres and opera houses who were paid by the performer(s) to create the illusion of an increased level of approval by the audience.
In Christianity, customs of the theatre were adopted by the churches. Eusebius says that Paul of Samosata encouraged the congregation to indicate approval of his preaching by waving linen cloths (), and in the 4th and 5th centuries applause of the rhetoric of popular preachers had become an established custom. Applause in church eventually fell out of fashion, however. Partly due to the influence of the quasi-religious atmosphere of the performances of Richard Wagner's operas at the , the reverential spirit that inspired this soon extended back to the theatre and the concert hall.
Protocol and variations
Well-recognized politicians, actors, and musicians often receive applause as soon as they first appear on stage, even before any performance activity has transpired. This accolade is given to indicate admiration for their past achievements, and is not a response to the performance the audience is attending.
Applause during church services is traditionally regarded as taboo, in light of the sanctity of the proceedings; stress is on the aspect of worship rather than the personality of the individual preaching or singing during the service. This rule may be relaxed to permit applause in honor of the newly married couple when they may turn to be greeted by the congregation following the exchange of vows. Applause may also be permitted at certain services in honor of a specific individual, such as a baptism or the ordination of a new priest or minister. In less traditional congregations, particularly in contemporary, evangelical megachurches, a more casual atmosphere exists and applause may be encountered as frequently as at any secular performance.
Indiscriminate applause is widely considered a violation of classical music concert etiquette: Applause is discouraged between movements, reserved instead for the end of the entire work. There have been a number of attempts to further restrict applause in various circumstances, e.g., court theaters in Berlin prohibit applause during the performance and before the curtain call (although elsewhere in Germany this is felt to be beyond public tastes).
By contrast, opera performances have traditionally been interrupted by applause at the end of an aria or certain other set pieces, and many opera scores reflect a break in the music at places where applause would typically occur. Regarding this practice as a distraction, Wagner headed it off by eliminating breaks in the score within each act; the arias in his operas do not end in a "full stop" but flow into the next section of the music, until the end of the act is reached. Even then, in light of the quasi-religious atmosphere of the first act of Parsifal, it is traditional for the audience not to applaud at all at the end of that act, but file out of their seats in silence.
In most performances, if spectators really enjoy a performance, mainly in classical performances, they may also accompany by throwing flowers onstage. The volume of applause after a performance has also been shown to change the evaluation of the performance by the audience.
