Power metal is a subgenre of heavy metal combining characteristics of traditional metal with speed metal, often within symphonic context. Generally, power metal is characterized by a faster, lighter and more uplifting sound, in contrast with the heaviness and dissonance prevalent for example in extreme metal. Power metal bands usually have anthem-like songs with fantasy-based subject matter and strong choruses, thus creating a theatrical, dramatic and emotionally "powerful" sound. The term was first used in the middle of the 1980s and 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 Scandinavia, Germany, Greece and Italy), South America (especially Brazil and Argentina) and Japan, with a lighter, more melodic sound and frequent use of keyboards.
