Metal=heavy Metal (according to wikipedia) Heavy metal (often referred to simply as metal) is a genre of rock music[1] that developed in the late 1960s and early 1970s, largely in England and the United States.[2] With roots in blues-rock and psychedelic rock, the bands that created heavy metal developed a thick, massive sound, characterized by highly amplified distortion, extended guitar solos, emphatic beats, and overall loudness. Heavy metal lyrics and performance styles are generally associated with machismo and masculine sexuality.
Death metal- is an extreme subgenre of heavy metal. It typically employs fast tempos, heavily distorted guitars, deep growling vocals, morbid lyrics, blast beat drumming, and complex song structures with multiple tempo changes.
Building off the speed and complexity of thrash metal, death metal emerged during the mid 1980s.
Black Metal- Black metal is an extreme subgenre of heavy metal. It often employs fast tempos, shrieked vocals, highly distorted guitars played with tremolo picking, double-kick drumming, and unconventional song structure.
During the first half of the 1980s, certain thrash metal bands established a prototype for black metal.
Black metal guitarists usually favour high pitched guitar tones and abundant distortion.[2] Typically, the guitar is played with much usage of fast tremolo picking.[2][3][4] When composing music, guitarists often use those scales, intervals and chord progressions that produce the most dissonant, fearful and ominous sounds. Additionally, guitar solos and low guitar tunings are a rarity in black metal.
