Power metal is a style of heavy metal combining characteristics of traditional metal with thrash metal or speed metal, often within symphonic context. The term refers to two different but related styles: the first pioneered and largely practiced in North America with a harder sound similar to speed metal, and a later more widespread and popular style based in Europe (Especially Germany, Italy and Scandinavia) with a lighter, more melodic sound and making frequent use of keyboards. Power metal can be seen as a parallel counterpart to extreme metal.
