 Power metal is a subgenre of heavy metal music combining characteristics of traditional metal with speed metal, often within symphonic context.
 Generally, power metal is characterized by a more uplifting sound, in contrast to the heaviness and dissonance prevalent in styles such as doom metal and death 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.
 Power metal has two distinct early styles, which developed in parallel.
 US Power Metal was developed in the mid/late 80s, pioneered by bands such as Omen characterized by harsh thrashy sound and a focus on speed and soaring operatic vocals.
 It was directly influenced by speed metal and NWOBHM, and had a drop in popularity in the 90s.
 European Power Metal was developed in the late 80s by key bands such as Helloween, and was more melodic, employing keyboards, synths and anthem-like songs.
Australian heavy metal music has its roots in both the Australian hard rock and pub rock tradition of the 1970s and the American and British heavy metal scenes.
 Since the mid-1980s, Australian heavy metal has been particularly influenced by foreign bands, particularly Swedish death metal, American thrash metal and black metal from Norway.
 Within Australia heavy metal has always remained part of the underground but since the mid-1990s many Australian metal acts have found widespread acceptance in overseas markets, particularly in Europe.
