The loud, distorted Hammond organ and occasionally the mellotron were popular with early metal bands these instruments were displaced in the 1970-80s by keyboards and synthesizers. Keyboards are often used to enhance the fullness of the sound. 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. Metal subgenres variously emphasize, alter, or omit one or more of these attributes. Heavy metal is traditionally characterized by loud distorted guitars, emphatic rhythms, dense bass-and-drum sound, and vigorous vocals.

3.2 Development: late 1960s and early 1970s.

Since the mid-1990s, popular styles such as nu metal, which often incorporates elements of funk and hip hop and metalcore, which blends extreme metal with hardcore punk, have further expanded the definition of the genre. Underground scenes produced an array of more extreme, very aggressive styles: thrash metal broke into the mainstream with bands such as Metallica, while other styles like death metal and black metal remain underground phenomena. In the mid-1980s, pop-infused glam metal became a major commercial force with groups like MГ¶tley CrГјe. Bands in the New Wave of British Heavy Metal such as Iron Maiden, Saxon, Diamond Head and MotГ¶rhead followed in a similar vein, introducing a punk rock influence and an increasing emphasis on the most dark sound. In the mid-1970s, Judas Priest helped spur the genre's evolution by discarding much of its blues influence. Although early heavy metal bands such as Led Zeppelin, Black Sabbath, and Deep Purple attracted large audiences, they were often critically reviled at the time, a status common throughout the history of the genre. Heavy metal has long had a worldwide following of fans commonly known as metalheads.

Heavy metal lyrics often talk about topics like social problems, politics, and drugs. The bands that created the electric blues-based heavy metal is really developed a thick, massive sound, characterized by highly amplified distortion, extended guitar solos, emphatic beats, and overall loudness. Within its his stylistic origins and musical influences we can mention best styles of the music genres as varied as blues rock, hard rock and psychedelic rock. Heavy metal (or simply metal) is a genre of rock music that developed during the 1960s to early 1970s, largely in the United States and the United Kingdom.
