Power metal is a fast, melodic, and anthemic branch of heavy metal that emphasizes uplifting melodies, soaring clean vocals, triumphant choruses, and virtuosic guitar and keyboard leads. Its lyrical focus often centers on fantasy, mythology, historical epics, and heroic narratives, aiming for a cinematic sense of grandeur. The genre coalesced in the mid-1980s from the speed and melody of NWOBHM and speed metal, then split into two recognizable strains: the more aggressive, riff‑driven U.S. power metal and the highly melodic, keyboard‑rich European style. Hallmarks include double‑bass drumming, harmonized twin‑guitar lines, neoclassical flourishes, and rousing sing‑along refrains designed for large audiences.

Speed metal is a fast, precision-driven branch of heavy metal that crystallized at the turn of the 1980s. It emphasizes aggressive tempos, tightly synchronized riffing, and virtuosic lead guitar work, while generally retaining melodic, often clean or strident vocals. Compared with thrash metal, speed metal tends to be less percussive and more melodic, favoring galloping rhythms, twin-guitar harmonies, and classic verse–chorus structures. Drums often employ rapid double-time feels and double-bass patterns, while bass frequently mirrors the rhythm guitar to reinforce propulsion. Lyrical themes range from rebellion and street realism to fantasy, warfare, and sci‑fi.

Heavy metal is a loud, guitar-driven style of rock defined by heavily distorted riffs, thunderous drums, and powerful vocals. Its musical language emphasizes minor modes, modal (Aeolian, Phrygian) riffing, and energy over groove, often featuring virtuosic guitar solos and dramatic dynamic contrasts. Emerging from late-1960s blues rock and psychedelic experimentation, heavy metal codified a darker, heavier sound with bands like Black Sabbath, Deep Purple, and Led Zeppelin. The genre values weight, intensity, and grandeur—whether through plodding, doom-laden tempos or galloping, high-energy rhythms—paired with themes that range from personal struggle and social critique to fantasy, mythology, and the occult.

Metal (often used to mean heavy metal in its broad, umbrella sense) is a loud, guitar-driven style of rock defined by high-gain distortion, emphatic and often martial rhythms, and a dense, powerful low end. It foregrounds riff-based songwriting, dramatic dynamics, virtuosic guitar solos, and commanding vocals that range from melodic wails to aggressive snarls and growls. Harmonically, metal favors minor modes, modal color (Aeolian, Phrygian), chromaticism, and tritone-inflected tension, while thematically it explores power, mythology, the occult, social critique, fantasy, and existential subjects. While adjacent to hard rock, metal typically pushes amplification, distortion, precision, and thematic intensity further, forming a foundation for many specialized subgenres.

Norsk rock refers to rock music from Norway, typically performed by Norwegian bands and often sung in Norwegian or regional dialects. It blends global rock idioms with distinctly Norwegian sensibilities, such as storytelling about everyday life, social issues, and a subtle sense of northern melancholy. Musically, norsk rock ranges from rootsy blues-rock and 70s-inspired classic rock to post-punk, alternative, and neo-psychedelia. Hallmarks include guitar-driven arrangements, strong choruses, and a balance between raw energy and melodic craft. Regional scenes in Oslo, Trondheim, Bergen, and Stavanger helped shape its diverse sounds. Over time, the genre became a cultural institution in Norway, with iconic bands defining generations and inspiring newer waves that connect local identity with international rock trends.
