Night Club

A nightclub (or night club or club) is a drinking, dancing and entertainment venue which does its primary business after dark. People who frequent nightclubs are known as clubbers. A nightclub is usually distinguished from bars, pubs or taverns by the inclusion of a dance floor and a DJ booth, where a DJ plays recorded dance and pop music.

The music in nightclubs is either live bands or, more commonly a mix of songs played by a DJ through a powerful PA system. Most clubs or club nights cater to certain music genres, such as techno, house music, heavy metal, garage, hip-hop, salsa, Dancehall, or Soca.
Types

Major cities in the United Kingdom and the US often have a variety of nightclubs, and some small towns and cities also have nightclubs. Nightclubs often feature lighting and other effects, to enhance the dancing experience. Lighting and effects include flashing colored lights, moving light beams, laser light shows, strobe lights, mirror-covered disco balls, or foam, and smoke machines.

Nightclub hours vary widely across the world; in areas with strict liquor regulations in place, nightclubs may have a legal requirement to close at a certain hour. These cities sometimes have illegal "after hours" clubs that stay open and serve alcohol after this legal closing time. In non-regulated areas, nightclubs stay open all night and into early daylight hours.

Entertainment is the main attraction at some types of nightclubs. One type of club is a concert club, which specializes in hosting performances of live music. In contrast to regular night clubs, concert clubs are usually only open when a performance is scheduled. Other types of clubs include "Underage" clubs, which
llow non-drinking age attendees.
Dancers move to the beat of a DJ's dance music at a nightclub

Nightclubs can be built in former warehouses and cinemas, underground buildings, and custom-built buildings, and generally have thick insulated walls and few or no windows, so that the neighboring buildings will not be disturbed by the powerful beat of the dance music and the flashing strobe lights. This style of construction also keeps light and noise from the street from entering the club.

This allows the nightclub to turn the dance floor into an alternate, illusory realm of timelessness. Even if an all-night rave at a nightclub lasts until 6 a.m., when it is light outside, to the clubgoers, it is still dark inside the club, and the partying and dancing continue. In most cases entering a night club requires a flat fee called a cover charge. Early arrivers and women often have cover waived (in the United Kingdom, this latter option is illegal under the Sex Discrimination Act 1975). Friends of the doorman or the club owner may gain free entrance. Sometimes, especially at larger clubs, one only gets a pay card at the entrance, on which all money spent in the discothèque (often including the entrance fee) is marked. Sometimes entrance fee and wardrobe costs are paid by cash and only the drinks in the club are paid using a pay card.
