Being quite a generic term, EDM has a variety of 'origins' and derivations. EDM can be said to stem from a fusion between regular dance music and electronic music. One notable example can be Donna Summer's 1977 single "I Feel Love", which combined elements of disco with electronic music. The innovative blend helped trigger several major EDM genres, such as Hi-NRG, Eurodance and techno music. Giorgio Moroder, who co-wrote the song and was also one of its producers, additionally created some of the earliest forms of electronic dance music. Kraftwerk are also credited as influencing electronic music. Whilst a lot of electronic dance music originates from disco, this is not the case for all EDM.
