Electronic dance music (EDM) is electronic music that is produced primarily for the purposes of use within a nightclub setting, or in an environment that is centered upon dance-based entertainment. The music is largely created for use by disc jockeys and is produced with the intention of it being heard in the context of a continuous DJ set; wherein the DJ progresses from one record to the next via a synchronized segue or "mix". Electronic dance music is a broad set of percussive music genres that largely inherit from the electronic music of Kraftwerk and 1970s disco music. Such music was originally born of and popularized via regional nightclub scenes in the 1980s. By the early 1990s, the presence of electronic dance music in contemporary culture was noted widely and its role in society began to be explored in published historical, cultural and social science academic studies. 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.

Since around the mid-1980s, electronic dance music has enjoyed popularity in many nightclubs, and is the predominant type of music played in discoth?ques as well as the rave scene. As such, the related term club music, while broadly referring to whichever music genres are currently in vogue and associated with nightclubs, has become synonymous with all electronic dance music, or just those genresor some subset thereofthat are typically played at mainstream discoth?ques. 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. 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.

Electronic dance music is categorized by music journalists and fans alike as an ever-evolving plethora of named genres, styles and sub-styles. With many types of dance music, the number of beats per minute (BPM) helps define a separation between genres. The presence of vocals, live instrumentation vs synthetic instrumentation, and pattern of drum beats also help differentiate genres of electronic dance music. Some genres, such as Techno, House, Trance, Electro, Hardstyle, breakbeat, drum and bass are primarily intended to promote dancing. Others, such as IDM, Dubstep, glitch and trip hop, are more experimental and tend to be associated more with focused listening than dancing.
