Electronic dance music: a range of genres of electronic music often played in nightclubs and characterised by a strong danceable beat (Dictionary.com)
House and techno are faster dance music styles with a bass drum on every beat (four-to-the-floor), often built on drum machines. These styles emerged from disco and electro and eventually gave birth to styles like electronic dance music (EDM), tropical house and more. (GCSE Bitesize)
