Generally, the songs are fast paced, and employ fantasy themes including (but not limited to) dragons, gladiators, warriors, valhalla, Lord of the Rings, polished steel weapons, and generally conceptual themes that deal with very "manly" concepts, at least in a historical sense. You will rarely find songs about love, sadness, or failure.
Power Metal is very uplifting, powerful music, that appeals to people who like to get inspiration from their tunes. Catchy, epic, and generally enjoyable as hell, Power Metal is a great genre that, regrettably, far too few people know about.
Being a very melodic style of metal, Power Metal is very intricate and difficult to write. It is one of the most difficult genres of metal to play, with Progressive (and Neoclassical) being possibly more difficult.
Lyrics commonly found in Power Metal are based around mythology, elves, war, greed, weaponry (most commonly swords), brotherhood, horses, magic, demons, dragons, and other fantasy-based topics. This makes Power Metal a perfect choice for D&D players (sadly, I am one) and people who enjoy fantasy novels.
this is real power metal.
