 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 "contend 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

Rhythm and tempo

The rhythm in metal songs is emphatic, with deliberate stresses. Weinstein observes that the wide array of sonic effects available to metal drummers enables the "rhythmic pattern to take on a complexity within its elemental drive and insistency." In many heavy metal songs, the main groove is characterized by short, two-note or three-note rhythmic figures—generally made up of 8th

He claims that metal's "most influential musicians have been guitar players who have also studied classical music. Their appropriation and adaptation of classical models sparked the development of a new kind of guitar virtuosity [and] changes in the harmonic and melodic language of heavy metal." The Grove Music Online states that the "1980s brought on ...the widespread adaptation of chord progressions and virtuosic practices from 18th-century European models, especially Bach, Wilhelm Richard Wagner and Vivaldi, by influential guitarists such as Eddie Van Halen

Deriving from the genre's roots in blues music, sex is another important topic—a thread running from Led Zeppelin's suggestive lyrics to the more explicit references of glam and nu metal bands. Romantic tragedy is a standard theme of gothic and doom metal, as well as of nu metal, where teenage angst is another central topic. Heavy metal songs often feature outlandish, fantasy-inspired lyrics, lending them an escapist quality. Iron Maiden's songs, for instance, were frequently inspired by mythology, fiction, and poetry, such as Iron Maiden's "Rime of the Ancient Mariner", based on the Samuel Taylor Coleridge

The thematic content of heavy metal has long been a target of criticism. According to Jon Pareles, "Heavy metal's main subject matter is simple and virtually universal. With grunts, moans and subliterary lyrics, it celebrates...a party without limits.... [T]he bulk of the music is stylized and formulaic." Music critics have often deemed metal lyrics juvenile and banal, and others have objected to what they see as advocacy of misogyny

While the case attracted a great deal of media attention, it was ultimately dismissed. In some predominantly Muslim countries, heavy metal has been officially denounced as a threat to traditional values. In countries including Morocco, Egypt, Lebanon, and Malaysia, there have been incidents of heavy metal musicians and fans being arrested and incarcerated.

Down-the-back long hair, according to Weinstein, is the "most crucial distinguishing feature of metal fashion." Originally adopted from the hippie subculture, by the 1980s and 1990s heavy metal hair "symbolised the hate, angst and disenchantment of a generation that seemingly never felt at home," according to journalist Nader Rahman. Long hair gave members of the metal community "the power they needed to rebel against nothing in general."

The classic uniform of heavy metal fans consists of "blue jeans, black T-shirts, boots and black leather or jeans jackets.... T-shirts are generally emblazoned with the logos or other visual representations of favorite metal bands." Metal fans also "appropriated elements from the S&M community (chains, metal studs, skulls, leather and crosses)." In the 1980s, a range of sources, from punk and goth music to horror films, influenced metal fashion. Many metal performers of the 1970s and 1980s used radically shaped and brightly colored instruments to enhance their stage appearance. Fashion and personal style was especially important for glam metal bands of the era. Performers typically wore long, dyed, hairspray-teased hair (hence the nickname, "hair metal"); makeup such as lipstick and eyeliner; gaudy clothing, including leopard-skin-printed shirts or vests and tight denim, leather, or spandex pants; and accessories such as headbands and jewelry.

Fan subculture

Deena Weinstein argues that heavy metal has outlasted many other rock genres largely due to the emergence of an intense, exclusionary, strongly masculine subculture. While the metal fanbase is largely young, white, male, and blue-collar, the group is "tolerant of those outside its core demographic base who follow its codes of dress, appearance, and behavior." Identification with the subculture is strengthened not only by the shared experience of concert-going and shared elements of fashion, but also by contributing to metal magazines and, more recently, websites.

The metal scene has been characterized as a "subculture of alienation", with its own code of authenticity. This code puts several demands on performers: they must appear both completely devoted to their music and loyal to the subculture that supports it; they must appear uninterested in mainstream appeal and radio hits; and they must never "sell out

Where the blues-rock drumming style started out largely as simple shuffle beats on small kits, drummers began using a more muscular, complex, and amplified approach to match and be heard against the increasingly loud guitar. Vocalists similarly modified their technique and increased their reliance on amplification, often becoming more stylized and dramatic. In terms of sheer volume, especially in live performance, The Who's "bigger-louder-wall-of-Marshalls" approach was seminal.

Though Judas Priest did not have a top 40 album in the U.S. until 1980, for many it was the definitive post-Sabbath heavy metal band; its twin-guitar attack, featuring rapid tempos and a nonbluesy, more cleanly metallic sound, was a major influence on later acts. While heavy metal was growing in popularity, most critics were not enamored of the music. Objections were raised to metal's adoption of visual spectacle and other trappings of commercial artifice, but the main offense was its perceived musical and lyrical vacuity: reviewing a Black Sabbath album in the early 1970s, leading critic Robert Christgau
