Electro house is a subgenre of house music that rose to become one of the most prominent genres of electronic dance music today. It combines the four to the floor beats commonly found in house music with harmonically rich analogue basslines, abrasive high-pitched leads and the occasional piano or string riff. The tempo of electro house ranges approximately from 120 to 130 bpm. The style is considered to have originated in the early 2000s. From the point of origin, electro house has developed various subgenres of its own.
