Drone metal (often called drone doom) is an extreme, minimalist offshoot of doom metal that centers on sustained tones, monumental volume, and glacial tempos. Rather than relying on riffs or conventional grooves, it foregrounds long, vibrating chords, amplifier feedback, and the physical presence of sound itself. Its textures are typically cavernous and monochromatic, with guitars tuned very low, notes held for extended durations, and percussion either sparse or entirely absent. Vocals—if present—range from ritualistic chants to guttural growls or distant murmurs, often treated as another layer of texture rather than a narrative lead. The result is immersive and meditative, yet crushing: a music of weight, space, and resonance that emphasizes timbre and decay over melody and rhythm.

Stoner metal is a heavy, riff-centered offshoot of doom metal that fuses the low-and-slow weight of early Sabbath with the hazy psychedelia and fuzz-drenched tones of 1970s hard rock. It emphasizes down-tuned guitars, thick midrange, and hypnotic, groove-forward drumming, often evoking a desert-heat mirage of sustained riffs and feedback. Compared to stoner rock, stoner metal leans darker and heavier, with a doomier pulse, longer song structures, and an almost trance-like fixation on repetition. Lyrics frequently explore cosmic wanderlust, occult imagery, apocalyptic visions, and cannabis counterculture, while production tends to favor warm, analog saturation and room-heavy drum sounds.

Sludge metal is a hybrid of doom metal’s slow, downtuned weight and hardcore punk’s raw aggression. It emphasizes thick, overdriven guitar tones, throttling bass, and drums that lurch between trudging slow-motion grooves and ragged mid‑tempo blasts. Vocals are typically screamed, barked, or anguished, often buried slightly in the mix to feel abrasive and cathartic. The style took shape in the late 1980s United States—particularly the Pacific Northwest and the American South—where bands fused Sabbath‑like doom riffs with the DIY harshness of hardcore and the scabrous textures of noise rock. Lyrical themes commonly explore addiction, despair, social decay, and Southern Gothic imagery, delivered with an intentionally gritty, unvarnished production aesthetic.

Epic doom metal is a doom metal substyle that emphasizes grandeur, melodicism, and a solemn, heroic atmosphere. It features slow to mid‑tempo, towering riffs; clear, dramatic, often operatic vocals; and lyrical themes drawn from mythology, tragedy, eschatology, fantasy, and historical epics. Compared with stoner/doom, its guitar tone is less fuzzy and more sculpted, with a crisp, heavy attack that leaves space for melodic leads and commanding vocals. Harmonic language leans on minor keys (often harmonic minor), stately chord movements, and memorable, anthem‑like motifs. Keyboards (organ, choir pads, mellotron) and choral overdubs are frequently used to heighten the monumental feel.

Traditional doom metal is the classic, Sabbath-rooted branch of doom that emphasizes weight, atmosphere, and repetition over speed or technical display. Its signatures are a monotonous and heavy playing style; repetitive, rough, and sometimes atonal guitar riffs; a "rocking to sleep" bass that locks to the guitar; and an unhurried, often swung or lurching drum feel. The harmony leans on minor pentatonic and Aeolian modes, with frequent tritone (flat‑5) colors and bluesy bends, drawing clear influence from both Blues Rock and Psychedelic Rock. Vocals are typically clean, plaintive, and dramatic—ranging from haunted croons to wailing laments—paired with lyrics about dread, mortality, esotericism, and the occult. Production tends to chase vintage warmth: tube amps, saturated fuzz, roomy drums, and organic reverb to let slow riffs breathe and brood.

Viking metal is a Scandinavian-born metal style that fuses the harsh timbres and riffing of black and heavy metal with epic, saga-like songwriting and Norse mythological themes. Compared to second‑wave black metal, it tends toward slower to mid‑tempo pacing, chanted or heroic clean vocals alongside growls, and grand, choir‑like arrangements. Folk instruments (fiddle, flute, nyckelharpa, tagelharpa, etc.) and modal melodies drawn from Nordic folk idioms are common, creating a windswept, seafaring atmosphere. Lyrically it focuses on pre‑Christian history, sagas, battle, nature, and pagan spirituality, favoring narrative storytelling and anthemic refrains over blasphemous or satanic topics typical of early black metal.
