Sung and screamed. Clean singing and harsh vocals trade off, often chorus against verse.

In short

Irish melodies and traditional instruments over black or heavy metal.

How it sounds

  • Tin whistle, bodhrán and fiddle woven into black or heavy metal arrangements.
  • Melodies taken from the traditional Irish repertoire, often directly.
  • Epic atmosphere with lyrics from Celtic myth and history.

The specifics

Tempo
120-170 bpm
Song length
5-9 min
Tuning
D or E standard alongside instruments in traditional keys — uilleann pipes, tin whistle and fiddle, which do not transpose to suit a guitarist.
Production
Layered and atmospheric rather than boisterous, with reverb used to give the traditional instruments space. The Irish records are notably more solemn than folk metal generally.
Written about
Irish myth and history, Colonialism and loss, Land, Paganism

What each part is doing

  • Uilleann pipes and whistle Carrying melody as lead instruments, in modal keys the guitars have to accommodate. The pipes are bellows-driven and cannot bend to a band's convenience.
  • Guitar Mid-tempo riffing that accompanies rather than leads, frequently in open voicings so the modal melodies do not clash.
  • Drums Mid-paced and processional, with blast beats used sparingly. Primordial's drumming is closer to a march than to extreme metal.
  • Vocals Sung and rasped by turns, declamatory rather than melodic — Alan Averill's delivery is the genre's most distinctive element.
  • Bass Simple and low, keeping the harmony legible under fast-moving modal tunes.

What it isn't

That it is folk metal with an Irish accent. The tone is entirely different: folk metal's default is celebration and Celtic metal's is grief, and the Irish bands are writing about colonisation and depopulation rather than about drinking. Primordial in particular sit closer to black metal than to anything with a fiddle in it.

Told apart from

  • Folk metal Folk metal is broadly cheerful and uses living dance music. Celtic metal is solemn, slower and more concerned with history and loss.
  • Pagan / Viking black metal Both grew out of black metal with pre-Christian subject matter. Celtic metal uses actual traditional instruments; pagan black metal usually does not.
  • Celtic rock Celtic rock does the same thing without metal's distortion or extremity, and predates it by twenty years.
  • Viking metal The Norse equivalent, and it writes its own melodies rather than borrowing traditional ones.

The genres this one is most often mistaken for. Written, not derived.

History

Cruachan were the first band to systematically combine black metal with Irish music, in 1995. Primordial went in a darker and more personal direction and became one of Ireland's most respected metal bands. The genre remains small but has a very clear identity.
