A death growl (or simply a growl) is a vocal style (an extended vocal technique) usually employed by death metal singers but also used in other heavy metal styles, such as metalcore. Death growls are sometimes criticized for their "ugliness". However, the harshness of death growls is in keeping with death metal's abrasive music style and often dark and obscene subject matter. The progressively more forceful enunciation of metal vocals has been noted from heavy metal to thrash metal to death metal.
Death metal, in particular, is associated with growled vocals. Death metal, which tends to be lyrically and thematically darker and more morbid than other forms of metal, features vocals that attempt to evoke chaos, death, and misery by being "usually very deep, guttural, and unintelligible". Natalie Purcell notes, "Although the vast majority of death metal bands use very low, beast-like, almost indiscernible growls as vocals, many also have high and screechy or operatic vocals, or simply deep and forcefully sung vocals." Sociologist Deena Weinstein has noted of death metal: "Vocalists in this style have a distinctive sound, growling and snarling rather than singing the words. Making ample use of the voice distortion box."
|"||To appreciate the music, fans first had to accept a merciless sonic signature: guttural vocals that were little more than a menacing, sub-audible growl. James Hetfield's thrash metal rasp was harsh in contrast to Rob Halford's heavy metal high notes, but creatures like Glen Benton of Deicide tore out their larynxes to summon images of decaying corpses and giant catastrophic horrors.||"|
Growls can be obtained with various voice effects, but the effects are usually used to enhance rather than create, and are seldom used at all. Voice teachers teach different techniques, but long-term use will still take its toll if done incorrectly - these techniques are designed to reduce rather than eliminate harm. However it has been shown by many vocalists (ex. Christian lvestam) that long-term use of these techniques can occur without causing harm to the voice. The techniques usually involve using the diaphragm and air pressure on the throat to form the sound, similar to forms of overtone singing. As a person tries to squeeze their throat, the sound gets less intense (usually used for higher growls/screams to decrease tension on chords). Some vocalists (ex. Danny Worsnop, Oliver Sykes) tend to use too much pressure on their throats and thus have vocal cord problems/defects. The Radboud University Nijmegen Medical Centre in The Netherlands reported in June 2007 that, because of the increased popularity of growling in the region, it was treating several patients who had performed the techniques incorrectly for edema and polyps on the vocal folds.
Growled vocals may have been a part of Viking music. In the 10th century, Arab-Spanish Sefardi Jewish merchant Abraham ben Jacob visited Denmark and commented on the local music as follows: "Never before I have heard uglier songs than those of the Vikings in Slesvig. The growling sound coming from their throats reminds me of dogs howling, only more untamed."
In Hildegard of Bingen's 12th-century allegorical morality play Ordo Virtutum, the role of the Devil uniquely does not employ melodic singing, but is performed in a manner which Hildegard specifies as strepitus diaboli and which is often taken to mean a low and growling voice.
In 1966, The Who released the song "Boris the Spider", which featured death growls sung in basso profondo by bass player John Entwistle. This can be considered one of the first uses of death growl in popular music.
The use of growling, "monstrous" vocals for ominous effect in rock music can be traced at least as far back as "I Put a Spell on You" by Screamin' Jay Hawkins in 1956. Mike Oldfield's "Tubular Bells, Part Two," from 1973, contains a section from 11:55 to 16:30 featuring extensive use of guttural vocals which are very close in style to the modern "death growl", however this effect was created by manipulating tape speed.
In 1969 and the early 1970s, the song "21st Century Schizoid Man" by King Crimson is notable for its heavily distorted vocals sung by Greg Lake. The songs "Iron Man" by Black Sabbath and "One of These Days" by Pink Floyd both contain brief passages of ominously growled, low-pitched vocals (in both cases studio-manipulated) against a heavy background of rock riffs. Other examples are Roger Waters' screams in some Pink Floyd songs, such as "Take Up Thy Stethoscope and Walk" (1967), "Careful with That Axe, Eugene" (1968). Punk rock bands like The Clash, Stiff Little Fingers, and 999 also regularly employed gruff sounding vocals, however nothing like the death growl common in metal music today. On the other hand, the low, raspy, aggressive pitch of Lemmy from Motrhead was not unlike the growl and can be thought to presage the current style.
The advent of the growl as it is used today coincided roughly with the gradual emergence of death metal, and it is thus difficult to pinpoint a specific individual as the inventor of the technique. Different vocalists likely developed the style over time. The band Death (and its precursor Mantas) with its two vocalists--initially Kam Lee and subsequently Chuck Schuldiner--have been cited as among the first (although Schuldiner would eventually switch to a more high-pitched screeching). Possessed are also considered by some to be one of the earliest bands to employ growls, as are Necrophagia and Master. Around the same time, bands such as Hellhammer, with Tom G. Warrior on vocals, and seminal act Massacre also employed a variation of the growl. Massacre vocalist Kam Lee's growls were highly guttural, low pitched and unintelligible compared to other death metal vocalists of the mid 1980s. This influenced the British Grindcore band Napalm Death. The vocalists from Napalm Death--consecutively Nic Bullen, Lee Dorrian and Mark "Barney" Greenway--further developed the style in the late 1980s, adding more aggression and deeper guttural elements to it, while also speeding up delivery of the lyrics. Another vocalist who gradually deepened his voice into the growling used today on death metal and grindcore was Chris Barnes, original vocalist of Cannibal Corpse, in the band's video biography, he states that he wanted to sing as high as Rob Halford, but his voice was too low pitched for that. So he started trying to blend it with the other instruments, coming up with a dark and really low guttural voice that became his signature. While Chris Barnes had a low voice, Matt Harvey of Exhumed could scream very high and always used "high vocals" in their songs. Frank Mullen of technical death metal band Suffocation was renowned for his innovative form of the death growl back when Suffocation's debut album Effigy of the Forgotten was released, with some sources claiming that it was the blueprint for the modern form of death growls.
