Hi-NRG

A style of uptempo disco or electronic dance music that originated in the United States and United Kingdom during the late 1970s. The genre is characterized by such elements as a four-on-the-floor rhythm and reverberated vocals. Hi-NRG and electrofunk have influenced the evolution of house music since the late 1980s. In the 1980s "Hi-NRG" referred not just to any high-tempo disco/dance music, but to a specific genre, only somewhat disco-like. Hi-NRG is, however, typified by an energetic, staccato, sequenced synthesizer sound of octave basslines or/and where the bass often takes the place of the hi-hat, alternating a more resonant note with a dampened note to signify the tempo of the record. There is also often heavy use of the clap sound found on drum machines.
