Exposed Artists in Dance
Dance music is a broad set of percussive music genres that largely inherit from 1970s disco music and, to some extent, the experimental pop music of Kraftwerk. Such music was originally borne of and popularized via regional nightclub scenes in the 1980s. It is constructed by means of electronic instruments such as synthesizers, drum machines and sequencers, and generally emphasizes the unique sounds of those instruments, even when mimicking traditional acoustic instrumentation. It sometimes encompasses music not primarily meant for dancing, but derived from the dance-oriented styles.

Dance music experienced a boom after the proliferation of personal computers in the 1980s, many music genres that made use of electronic instruments developed into contemporary styles mainly thanks to the MIDI protocol, which enabled computers, synthesizers, sound cards, samplers and drum machines to control one another and achieve the full synchronization of sounds. Electronic dance music is typically composed using computers and synthesizers, and rarely has any physical instruments. Instead, this is replaced by digital/electronic sounds, with a 4/4 beat. Dance music typically ranges from 120bpm, up to 200bpm, with techno, trance, and house being the most widespread. Many producers of this kind of music however, such as Darren Tate and MJ Cole, were trained in classical music before they moved into the electronic medium.

Since around the mid-1980s, electronic dance music has enjoyed popularity in many nightclubs, and, as of 2006, is the predominant type of music played in discothèques as well as the rave scene. As such, the related term club music, while broadly referring to whatever music genres are currently in vogue and associated with nightclubs, has, for some, become synonymous with all electronic dance music, or just those genres — or some subset thereof — that are typically played at mainstream discothèques. It is sometimes used more broadly to encompass non-electronic music played at such venues, or electronic music that is not normally played at clubs but that shares attributes with music that is. What is widely considered to be club music changes over time, includes different genres depending on the region and who's making the reference, and may not always encompass electronic dance music. For example, as of 2006, hip hop music, being widely played in clubs, is one form of "club music" to many, but a smaller percentage would describe it as being a form of electronic dance music. Similarly, electronic dance music sometimes means different things to different people. Both terms vaguely encompass multiple genres, and sometimes are used as if they were genres themselves. The distinction is that club music is ultimately based on what's popular, whereas electronic dance music is based on attributes of the music itself.
