Sung. Melodic singing throughout.

In short

Serious instrumental metal under J-pop idol vocals and choreography. It reads like a joke on paper and works perfectly live.

How it sounds

  • Metal instrumentation played by session musicians of a very high standard.
  • J-pop idol melodies and vocals with synchronised choreography.
  • Dense production built on the deliberate contrast between sweet and brutal.

Hear what that means

  • The splice

    Babymetal - Babymetal

    A djent breakdown cutting to an idol-pop chorus with no bar of preparation. The whiplash is composed rather than clumsy, and the arrangement is the actual instrument here.

  • Session players, taken seriously

    Babymetal - Metal Resistance

    Down-tuned seven-string riffing at a standard any metal band would be pleased with, under a vocal melody pitched an octave and a half above it.

  • Written and played by the band

    Band-Maid - World Domination

    The counter-example inside the same genre: a self-contained band writing its own material, which addresses the authorship objection people usually raise about the format.

The specifics

Tempo
140-200 bpm
Song length
3-4.5 min
Tuning
Down-tuned seven-strings behind vocals pitched an octave or more above them — the extreme separation between the two is the genre's defining sound.
Production
Maximalist and digitally exact: session-grade metal playing, J-pop vocal production, and edits between the two that are deliberately abrupt rather than blended.
Written about
Adolescence, Fandom, Food, chocolate and other deliberately trivial subjects, Metal itself, affectionately

What each part is doing

  • Guitar Played by hired session musicians to a very high standard, in whatever subgenre the song calls for — djent, power metal, thrash — often changing between sections.
  • Drums Double kick and blast beats under an idol-pop vocal melody, which is the collision the entire genre is built on.
  • Vocals Sung in the Japanese idol style: high, bright, unmodified by rock phrasing, and arranged in call-and-response between a lead and two supporting voices.
  • Arrangement The real instrument. Sections are spliced rather than transitioned — a breakdown cutting to a pop chorus with no bar of preparation — and the whiplash is composed, not clumsy.

What it isn't

That it is a joke or a marketing product. It is a production-team genre, which is normal in Japanese pop and unfamiliar in metal, and the musicians involved are extremely good. The discomfort in the Anglophone metal audience is mostly about authorship — the idea that a band should write its own material and mean it — which is a local convention rather than a universal one, and the records themselves are far more technically serious than the format suggests.

Told apart from

  • Power metal Power metal is the closest thing on the metal branch in sheer melodic ambition, and it plays its sincerity straight. Kawaii metal frames the same sincerity inside pop. Side by side →
  • Nu metal Both splice metal to a genre from outside it. Nu metal took hip-hop's rhythm; this takes J-pop's melody and vocal arrangement. Side by side →
  • Symphonic metal Both put a high, trained-sounding female voice over heavy guitars. Symphonic metal's is operatic and the mood is grand; this is idol-pop and the mood is bright. Side by side →
  • Alternative metal Alternative metal is where the habit of splicing metal to something incompatible starts, and it does it within one band rather than across a production team. Side by side →

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

History

Babymetal was created in 2010 as a subunit of a Japanese idol group, on the apparently absurd premise of combining J-pop with metal. It reached Wembley Arena and Glastonbury, backed by some of Japan's finest session players. Band-Maid, in parallel, play heavy rock in maid costumes and are entirely serious about the music.
