Death metal is a subgenre of heavy metal generally involving low tuned guitars played with tremolo picking and many solos, double
kick or blast beat drumming techniques, minor
keys or atonality, and rapid time signature changes, chromatic chord progressions, and intricate song-writing. Death metal is the most underrated and underappreciated genre in music, with many of the most famous bands full of world class musicians that taught at the most prestigious music schools in the
world. The best aspects of every genre of music (new wave of
British heavy metal, classical musical, thrash metal, grindcore,
black metal and jazz) can be found in death metal albums articulated in a more intelligent and enjoyable manner than in the aforementioned genres. Examples are
Atheist's take on jazz, Arghoslent's NWOBHM riffs, Necrophagist's Beethoven-influenced riffs, and Appalling Spawn's grindcore elements. Death metal produces the most thought-provoking and intelligent lyrics of any genre as referenced below.
Guy 1: Why do you think death metal appeals almost exclusively to very intelligent
people?
Guy
2: As illuminated in the documentary The Boy With the Incredible Brain, many very high IQ
people think in terms of shapes and music that forms shapes. It is not hard to understand why the ebb and flow of death metal riffs appeal almost exclusively to very intelligent
people who sense and recognize the shape and contours of the very intricate and highly educated music that is death metal.
