Electronic dance music, often simplified as EDM, (occasionally referred to as electronica or dance) is a form of electronic music which is meant to be danced to, often in the setting of a nightclub, discothèque or party. Generally, electronic dance music is created by producers and composers, and is then used by DJs, or disc jockeys, in the above settings. Electronic dance music takes many forms and styles. As a genre, it is generally up-tempo music created by electronic software and machines, such as synthesizers, drum machines, keyboards, samplers, sequencers and computers. Occasionally, the term "techno" is used to describe electronic dance music in general, despite being a generalisation as techno is a distinguishable subgenre of EDM.
