Description
Mathgrind is an extreme fusion of mathcore’s jagged rhythmic complexity with grindcore’s hyper‑speed, brevity, and abrasion.
Expect songs that last seconds to a couple of minutes, filled with whiplash changes, odd‑meter riffs (e.g., 7/8, 13/16), metric modulations, and relentless blast beats. Guitars and bass are highly distorted and tightly gated, favoring dissonant interval sets (minor 2nds, tritones, cluster voicings), rapid taps/sweeps, and sudden stop‑start figures. Vocals range from piercing screams to guttural barks, often delivered in short, cathartic bursts that mirror the music’s cut‑up architecture.
Where grindcore pursues speed and ferocity and mathcore pursues rhythmic sophistication, mathgrind deliberately maximizes both—resulting in music that feels simultaneously chaotic and surgically precise.
History
Foundations (late 1990s)
• The roots of mathgrind lie in the convergence of U.S. mathcore and the most technical strains of grindcore. Bands like The Dillinger Escape Plan pushed hardcore into acrobatic meters and complex song forms, while highly technical grind (e.g., Discordance Axis) showed how speed and precision could coexist.
Codification and Naming (2000s)
• In the early–mid 2000s, a crop of groups began writing grind‑length songs using distinctly mathcore syntax—irregular meters, constantly shifting subdivisions, and polyrhythmic stabs—leading fans and writers to adopt “mathgrind” as a handy label.
• DIY circuits, file‑sharing, and online message boards/zines helped disseminate recordings rapidly, encouraging bands to push technicality and micro‑song construction even further.
Expansion and Cross‑Pollination (2010s)
• The style influenced adjacent micro‑scenes: cybergrind producers integrated mathy patterning into programmed drums; nintendocore bands fused chiptune timbres with mathgrind’s rhythmic whiplash; and modern deathcore borrowed blast‑centric, start‑stop figures and odd‑meter breakdowns.
• International acts adopted the approach, but the core aesthetic—short form, extreme tempos, and highly discontinuous structures—remained consistent.
Present Day (2020s)
• Mathgrind persists as a niche yet influential vocabulary. Its techniques percolate into technical grind, cybergrind, and avant‑heavy scenes, while the classic 2000s recordings continue to serve as templates for writing hyper‑compressed, rhythm‑forward extreme music.
How to make a track in this genre
Rhythm and Meter
• Start from grindcore tempos (230–300+ BPM) and write in asymmetrical meters (7/8, 5/4, 11/8) and mixed bars (e.g., 7/8 + 9/8 + 4/4).
• Use metric modulation and frequent tempo/meter cuts; arrange riffs as short cells that can be reordered or interrupted abruptly.
Drums
• Employ blast beats (traditional, hammer, gravity) and d‑beats; punctuate with sudden rests and cymbal chokes to articulate form.
• Layer polyrhythms (e.g., snare accents in 3 over a 4‑subdivided guitar figure) and use tight kicks to mirror guitar stabs.
Guitars and Bass
• Tunings: Drop C/B or extended‑range (7/8‑string) for clarity at speed.
• Vocabulary: dissonant dyads (m2), tritones, chromatic runs, cluster chords, wide‑interval tapping; alternate between palm‑muted staccato and open‑string flurries.
• Bass should lock with kicks; use pick attack, slight drive/fuzz, and occasional tapping to cut through dense guitars.
Harmony and Texture
• Favor atonal/contrapuntal motion over scalar riffs; interleave contrary lines between guitars when arranging for two guitars.
• Use abrupt dynamic pivots: full‑band blasts → single‑instrument hits → tutti re‑entry.
Vocals and Lyrics
• Harsh vocals (screams, barks, shrieks). Keep phrasing short to match micro‑riffs.
• Lyrical themes range from surrealist and satirical to socio‑political; the delivery should feel percussive.
Structure and Form
• Keep tracks concise (0:20–1:40 is common). Build from 6–12 distinct cells rather than verse/chorus.
• Employ jump‑cuts, false endings, and sudden reprises to maintain volatility.
Sound and Production
• Tight gating, fast transients, and minimal room wash. Prioritize clarity of attacks so odd meters remain intelligible.
• Hard edit transitions (tape stops, mutes) to emphasize the cut‑up aesthetic.
Workflow Tips
• Compose to a click with changing time‑signature markers; notate or grid riffs to avoid drift at extreme tempos.
• Rehearse transitions in isolation; the ‘silence as punctuation’ is as important as the notes.
• Start with a 30–60 second piece containing at least three meters and two blast‑beat variants, then iterate.
