WHAT IS HEAVY METAL MUSIC?
Heavy metal (often referred to simply as metal) is a genre of rock music that developed in between 1968 and 1974 , largely in the United Kingdom and the United States.With roots inblues-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 masculinity and machismo. The first heavy metal bands such as Led Zeppelin, Black Sabbath and Deep Purple attracted large audiences, though they were often critically reviled, a status common throughout the history of the genre. In the mid-1970s Judas Priest helped spur the genre's evolution by discarding much of its blues influence; Motörhead introduced a punk rock sensibility and an increasing emphasis on speed. Bands in the New Wave of British Heavy Metal such as Iron Maiden followed in a similar vein. Before the end of the decade, heavy metal had attracted a worldwide following of fans known as "metalheads" or "headbangers". In the 1980s, glam metal became a major commercial force with bands like Mötley Crüe and Ratt. Underground scenes produced an array of more extreme, aggressive styles: thrash metal broke into the mainstream with bands such as Metallica and Megadeth, while other styles likedeath metal and black metal remain subcultural phenomena. Since the mid-1990s, popular styles such as nu metal, which often incorporates elements of grunge and rapping; andmetalcore, which blends extreme metal with hardcore, have further expanded the definition of the genre.
Heavy metal is traditionally characterized by loud distorted guitars, emphatic rhythms, dense bass-and-drum sound, and vigorous vocals. Metal subgenres variously emphasize, alter, or omit one or more of these attributes. New York Times critic Jon Pareles writes, "In the taxonomy of popular music, heavy metal is a major subspecies of hard-rock—the breed with less syncopation, less blues, more showmanship and more brute force." The typical band lineup includes a drummer, a bassist, a rhythm guitarist, a lead guitarist, and a singer, who may or may not be an instrumentalist. Keyboard instruments are sometimes used to enhance the fullness of the sound. The electric guitar and the sonic power that it projects through amplification has historically been the key element in heavy metal. The lead role of the guitar in heavy metal often collides with the traditional "frontman" or bandleader role of the vocalist, creating a musical tension as the two "contends for dominance” in a spirit of “affectionate rivalry". Heavy metal "demands the subordination of the voice" to the overall sound of the band. Reflecting metal's roots in the 1960s counterculture, an "explicit display of emotion" is required from the vocals as a sign of authenticity. Critic Simon Frith claims that the metal singer's "tone of voice" is more important than the lyrics. Metal vocals vary widely in style, from the multioctave, theatrical approach of Judas Priest's Rob Halford and Iron Maiden's Bruce Dickinson, to the gruff style of Motörhead's Lemmy and Metallica's James Hetfield, to the growling of many death metal performers, and to the harsh screams of black metal. The prominent role of the bass is also key to the metal sound, and the interplay of bass and guitar is a central element. The bass guitar provides the low-end sound crucial to making the music "heavy". Metal basslines vary widely in complexity, from holding down a low pedal point as a foundation to doubling complex riffs and licks along with the lead and/or rhythm guitars. Some bands feature the bass as a lead instrument, an approach popularized by Metallica's Cliff Burton in the early 1980s. The essence of metal drumming is creating a loud, constant beat for the band using the "trifecta of speed, power, and precision"....
