Heavy Metal

Heavy metal or metal is a genre of rock music that developed between 1968 and 1974 , largely in the United Kingdom and the United States. 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.
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 like death 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; and metalcore, 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.

Heavy metal is typically characterized by a guitar-and-drum-dominated sound, strong rhythms and classical, bluesy or symphonic styles. However, heavy metal sub-genres have their own stylistic variations on the original form that often omit or alter many of these characteristics. There is a very wide variety of sounds and styles within the genre of Metal.

The most commonly used line-up for a metal band is a drummer, a bassist, a rhythm guitarist, a lead guitarist, and a singer (who may or may not be an instrumentalist). Keyboards were popular with early metal bands (especially the organ and occasionally the mellotron), but were gradually used less and less frequently. Today they are used by some styles (prog metal, later black metal) and shunned by others, though as different subgenres develop they have begun to become more popular. The guitar and the sonic power that it projects through amplification, however, is the key element in heavy metal music. Distortion of the guitar sound is used to create a more powerful, "heavy'" sound. Later, more intricate solos and riffs became a big part of heavy metal music. Guitarists use sweep-picking, tapping and other advanced techniques for rapid playing, and many sub-genres praise virtuosity over simplicity. Also, as technology has developed, new ways of altering the guitar's sound have been
adopted.

Metal vocals vary widely in style. Vocalists' abilities and styles range from the multi-octave theatrical vocals of Judas Priest's Rob Halford and Iron Maiden's Bruce Dickinson, to the intentionally gruff vocals of Metallica's James Hetfield and Lemmy from Motörhead .
