Horror synth is a dark, cinematic electronic style that draws heavily from 1970s–1980s horror film scores and analog synthesizer aesthetics. It emphasizes ominous arpeggios, minor-key ostinati, and brooding pads that evoke suspense, dread, and retro VHS-era atmosphere. While it overlaps with synthwave, horror synth is noticeably darker and more aggressive, often incorporating industrial textures, dissonant intervals, and sound-design cues taken from classic slasher and giallo soundtracks. The music typically features vintage drum machine grooves, tape-like saturation, and motif-driven themes that feel like cues to an unseen film.

Instrumental death metal is death metal that omits vocals entirely while preserving the genre’s defining sonic traits—downtuned and highly technical guitar work, rapid double‑kick and blast‑beat drumming, dissonant harmonies, and volatile dynamics. Without growled vocals as a focal point, the music shifts toward compositional detail: intricate riff architecture, lead‑guitar counterpoint, bass virtuosity (often with tapping and chordal playing), and drumming that toggles between surgical precision and controlled chaos. Many bands draw on progressive metal, djent, and jazz‑fusion language, favoring odd meters, rapid metric modulation, modal mixture (especially Aeolian/Phrygian flavors with added chromaticism), and tightly gated, ultra‑articulate production. The result is music that feels as heavy and extreme as traditional death metal but reads more like an instrumental narrative—riff suites, thematic development, and textural interludes substitute for lyrical content.

Melodic death metal (often shortened to melodeath) blends the speed, aggression, and harsh vocals of death metal with the harmonized guitar leads, memorable melodies, and songcraft of traditional heavy metal and thrash. It is characterized by twin‑guitar harmonies, fast tremolo riffs, punchy palm‑muted rhythms, and growled or screamed vocals, often contrasted with catchy, clearly articulated lead lines. Compared to traditional death metal, the genre favors stronger tonal centers, consonant interval harmonies (thirds and sixths), and more accessible structures, while retaining double‑kick intensity and occasional blast beats. Production tends to be tighter and clearer than early death metal, and many bands incorporate keyboards for texture. The style is strongly associated with the early–mid 1990s Gothenburg scene in Sweden, though parallel strains also emerged in the UK and Finland.

Progressive metal blends the ambition and extended song forms of progressive rock with the heaviness, timbre, and energy of heavy metal. It is characterized by complex arrangements, frequent time‑signature changes, virtuosic instrumental passages, thematic or concept‑driven albums, and a wide dynamic range from delicate, atmospheric sections to aggressive, high‑gain climaxes. Harmonically it draws on modal interchange, chromatic voice‑leading, and jazz‑fusion colors, while rhythmically it favors polymeters, polyrhythms, and metric modulation. Keyboards and layered production often add orchestral or cinematic scope.

Death metal is an extreme subgenre of heavy metal defined by heavily distorted, low‑tuned guitars, rapid and complex riffing, blast beat drumming, and harsh guttural vocals. Its harmonic language favors chromaticism, dissonance, and tremolo-picked lines that create an ominous, abrasive atmosphere. Lyrically, death metal often explores dark or transgressive themes—mortality, mythology, anti-religion, psychological horror, and the macabre—sometimes with philosophical or social commentary. Production ranges from raw and cavernous to hyper-precise and technical, reflecting the genre’s many regional scenes and substyles. From the mid‑1980s Florida scene (Tampa) and parallel developments in the US, UK, and Sweden, death metal evolved into numerous branches including brutal death metal, technical death metal, melodic death metal, and death‑doom, each emphasizing different aspects of speed, complexity, melody, or heaviness.

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.
