Celtic metal is a fusion of heavy metal with the traditional music of the Celtic nations, especially Ireland and Scotland. It blends distorted guitars, bass, and drums with folk instruments such as uilleann pipes, tin whistle, fiddle, bouzouki, harp, and bodhrán. Stylistically, it often borrows rhythmic cells from jigs and reels (in 6/8 or 12/8), employs modal harmony (Dorian and Mixolydian are common), and incorporates pentatonic and drone-based melodies. The lyrical focus typically explores mythology, folklore, history, and landscapes of the Celtic world, delivered through a mix of harsh and clean vocals, sometimes in Gaelic or other Celtic languages. The result ranges from epic, melodic arrangements to blackened, atmospheric soundscapes, maintaining a strong sense of place and tradition within a metal framework.

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.
