Eurobeat refers to two styles of dance music that originated in Europe: one is a British variant of Italian Eurodisco-influenced dance-pop, and the other is a hi-NRG-driven form of Italo disco. Both forms were developed in the 1980s. Producer trio Stock Aitken Waterman and pop band Dead or Alive made Eurobeat music more popular in the United States, where Eurobeat was historically marketed as hi-NRG (pronounced as "high energy"). For a short while, it also shared this term with early freestyle music and Italo disco. Overview In the late 1970s, Eurodisco musicians such as Silver Convention and Donna Summer were popular in America. In the 1980s, a highly polished production with "musical simplicity" at its core — from Bubblegum Pop-like lyrics, catchy (in some cases Italian, in other Eurodisco-like) melodies, to "elementary" song structures — an average British Eurobeat song took very little time to complete. Bananarama's "Venus" and Mel & Kim's "Showing Out (Get Fresh at the Weekend)" were said to be completed in a day, according to Pete Waterman of Stock Aitken Waterman. Eurobeat lyrics and melody are very simple. Italo disco, sometimes fast and happy music like EDM, with a sequenced octave bassline. Many feature guitars as a beginning section, followed by a thunderous, highly technical synthesizer riff which is then repeated after the chorus. Songs usually repeat the verse, bridge, and chorus multiple times during the song. The beginning is typically like an instrumental rendition of the verse, bridge, and chorus, while the riff is a lot like an instrumental version of the chorus. Use of the term British record producer Ian Levine's Eastbound Expressway, released the single "You're a Beat" in recognition of the slower tempo of hi-NRG music emerging from Europe. Many European acts managed to break through under this new recognition, namely the likes of Modern Talking, Bad Boys Blue, Taffy, and Spagna. The term "Eurobeat" was subsequently used commercially to describe the Stock Aitken Waterman–produced hits by Dead or Alive, Bananarama, Jason Donovan, Sonia, and Kylie Minogue which were heavily based on the British experience with Italo disco. During 1986–1988, it was used for specific Italian 1980s Eurodisco imports, such as Sabrina Salerno, Spagna, and Baltimora but was also used in the United States as a catch-all term for UK-based dance and electropop groups of the time such as Pet Shop Boys, purported to have a "European beat", hence Eurobeat.
