Heavy metal music

In music, heavy metal is progenitor of the "Metal-family" (for ex. heavy metal, black metal, death metal...). Metal derives directly from blues and rock, even if in some sub-genres there is an evident influence of classical music. So, even if heavy metal and black metal belong to the same family, there is an effective difference between them. Heavy metal is mainly blues-based, with pentatonic scales and a blues-like song structure; black metal is based on classical music, even if at a first glance it seems to be only distorted guitars playing very fast a repeating melody.

Heavy Metal developed out of Sixties Rock and Blues when musicians started to exploit the opportunities of the electrically amplified guitar to produce a louder, more discordant sound. The origin of the term "Heavy Metal" is uncertain. Some theories hold that it was coined by one of the critics for Rolling Stone Magazine. Others have attempted to trace its origin to the words "heavy metal thunder" in the Steppenwolf song "Born to be Wild", or the William S. Burroughs story "The Heavy Metal Kid". Regardless of its origin, the term may have been used as a jibe initially but was quickly adopted by its adherents. Bands such as Led Zeppelin, Deep Purple and Black Sabbath specialised in a "stripped down" sound in which the Blues inheritance was reduced. The influence of Jimi Hendrix should not be discounted though, acting as both an innovator in the technical capabilities of the electric guitar and a bridge between black music and white European rockers. Some of the original Heavy Metallers joked that their simplified sound was more the result of limited ability rather the desire to innovate.

Some people say The Beatles started to ignite the metal music movement with their album of Sgt. Pepper Lonely's Hearts Club Band, and the song "Helter Skelter" from The Beatles. This opinion, however, is open for debate. The earliest song that is clearly identifiable as prototype heavy metal appears to be 'You Really Got Me' by The Kinks.

The American band Grand Funk Railroad epitomised early heavy metal, and set an alternative benchmark in which the volume of the music was seen as the important factor rather than its musical qualities. Douglas Adams neatly satirised this propensity for excessive volume in The Hitch Hikers Guide to the Galaxy with the fictional rock band Disaster Area - creators of the loudest sound in the known universe. It should be noted however, that Adams was satirising Pink Floyd stage shows specifically - rather than metal in general.

The energetic and vitalised music soon found an audience and rapidly spread to the United States through extended touring. American musicians swiftly absorbed the agitated style and began to restore a more technically refined element as well as the Blues element.

An element to be pointed out is that heavy metal is considered by many to be white/European, in opposition to the blues-based rock, which derives from Afro-American music. This only means that the majority of the audience and the players seem to be white. There are, if one chooses to look, several examples of bands that have disproved this stereotype and the audiences can be quite mixed.

In the early 80s the New Wave of British Heavy Metal made metal music very popular (especially in Europe) with Bands like Iron Maiden, Judas Priest and Motörhead. This period influenced all metal sub-genres and can be considered as their common roots. Sub-genres of heavy metal are numerous:

Thrash Metal: A very aggressive and rhythm-based style of metal. Examples are Slayer, Overkill and early Metallica
Power Metal: Clean vocals and hymn-like choruses are charactistic for this style. The lyrics are often based on fantasy or sci-fi themes. The most famous bands are: Iron Maiden, Helloween, Blind Guardian and Hammerfall, the first of which is British and the latter three continental European.
Death Metal: Extreme music with low-pitched guitars and growling vocals. There is no common theme in the lyrics, they range from splatter (Cannibal Corpse) and war (Bolt Thrower) to Christian motives (Mortification). Besides the mentioned, Death, Morbid Angel and Entombed are other important bands.
Black Metal: A precise defintion for this style is very hard to give. One approach is strictly based on the lyrics, which are satanic or otherwise occult. Bands: Mayhem, Darkthrone and Venom (early black metal).
Nu Metal: Newest form of heavy metal, usually features down tuned guitars (7 string guitars are common), sampling artists/DJs and angst-ridden, hip-hop influenced vocals.
Goth Metal fuses the bleak, icy atmospherics of goth rock with the loud guitars and aggression of heavy metal, finding the middle ground between the two styles in a melodramatic sense of theater and lyrical obsessions with religion and horror. Bands: Theatre of Tragedy, Paradise Lost, Lacrimosa and My Dying Bride.
Doom Metal is inspired largely by the lumbering dirges and stoned, paranoid darkness of Black Sabbath, doom metal is one of the very few heavy metal subgenres to prize feel and mood more than flashy technique. Bands: Candlemass, Cathedral and Anathema.
Neo-Classical Metal: The most renowned artist is the Swedish axeman Yngwie J. Malmsteen. In neo-classical metal, the traditional toolbox of metal song-writing is used, but with a twist: all of it takes place in a structure that is heavily influenced by baroque music. The chord progressions, arpeggios, broken chords, and speedy scale runs of neo-classical metal are borrowed for the most part from Johann Sebastian Bach, Antonio Vivaldi and Niccolo Paganini. Although Malmsteen is the most well-known proponent of this evolution of metal, however, classical elements used in heavy metal and hard rock date back to Ritchie Blackmore of Deep Purple and Eddie Van Halen's innovations in the 1970s.
Progressive metal: combines elements of progressive rock and heavy metal. Bands include Dream Theater and Symphony X.
Glam metal: Glam focused on stage craft and appearance (leather, spandex, long hair and makeup being very common), and generally uses a lot of "feel good" rhythms and catchy lyrics. Glam Bands: Motley Crue, Ratt, Poison, Dokken, Vixen, and Cinderella among many, many others.

The most used lineup for metal is: a drummer, sometimes using a double bass-drum; a bass guitar; a rhythm guitar; a lead guitar; a singer; sometimes a keyboard player can be found. Guitar playing is very important in heavy metal. Intricate solos and riffs are a big part of heavy metal music. Guitarists use sweep-picking, tapping and similar techniques to obtain amazing fast playing. Heavy metal is not limited, however, to the standard outfit of guitars and drums. The Finnish cello quartet, Apocalyptica, has created their own version of heavy metal, difficult to categorize but leaning towards the darker side of metal. They apply various familiar effects to their sounds such as the all-familiar distortion, chorusing, flanging, etc. to create their style, which has fallen under a mixed assortment of applause and criticism due to their deviance.

There is a great variety of ways that heavy metal singers sing, from clean vocals to a high-pitched wail to a deep growl. The black and death metal scene tend to use distorted and guttural voices (for example try to listen to some songs of the Florida band Deicide). Generally it's hard to understand what the singer is "singing". Often, the text is considered to be too crude to be spoken out clearly (try to listen to Cannibal Corpse), but there are some bands that will have very good lyrics obscured by the style of the singing.
