Power metal

Power metal is a style of heavy metal music 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, Scandinavia) and Japan (early Visual Kei bands) with a lighter, more melodic sound and frequent use of keyboards.
