BBC Radio 1
BBC Radio 1 is a British radio station operated by the British Broadcasting Corporation which broadcasts internationally, specialising in modern popular music and current chart hits throughout the day. Radio 1 provides alternative genres after 7 pm, including electronica, hip hop and indie; the choice of music and presenting style is that of programme hosts, however those who present in the daytime have to rotate a number of songs a specific number of times per week. It was launched in 1967 to meet the demand for music generated by pirate radio stations, when the average age of the UK population was 27; the BBC claim that they target the 15–29 age group, the average age of its UK audience since 2009 is 30. BBC Radio 1 started 24-hour broadcasting on 1 May 1991. Radio 1 was established in 1967 as a successor to the BBC Light Programme, which had broadcast popular music and other entertainment since 1945. Radio 1 was conceived as a direct response to the popularity of offshore pirate radio stations such as Radio Caroline and Radio London, outlawed by Act of Parliament.
Radio 1 was launched at 6:55 am on Saturday 30 September 1967. Broadcasts were on 247 metres high wave, using a network of transmitters which had carried the Light Programme. Most were of comparatively low power, at less than 50 kilowatts, leading to patchy coverage of the country; the first disc jockey to broadcast on the new station was Tony Blackburn, whose cheery style, first heard on Radio Caroline and Radio London, won him the prime slot on what became known as the "Radio 1 Breakfast Show". The first words on Radio 1 – after a countdown by the Controller of Radios 1 and 2, Robin Scott, a jingle, recorded at PAMS in Dallas, beginning "The voice of Radio 1" – were: And, good morning everyone. Welcome to the exciting new sound of Radio 1; this was the first use of US-style jingles on BBC radio, but the style was familiar to listeners who were acquainted with Blackburn and other DJs from their days on pirate radio. The reason jingles from PAMS were used was that the Musicians' Union would not agree to a single fee for the singers and musicians if the jingles were made "in-house" by the BBC.
The first music to be heard on the station was "Theme One", specially composed for the launch by George Martin. It was followed by an extract from "Beefeaters" by Johnny Dankworth; the first complete record played on Radio 1 was "Flowers in the Rain" by The Move, the number 2 record in that week's Top 20. The second single was "Massachusetts" by The Bee Gees; the breakfast show remains the most prized slot in the Radio 1 schedule, with every change of breakfast show presenter exciting considerable media interest. The initial rota of staff included John Peel and a gaggle of others, some transferred from pirate stations, such as Keith Skues, Ed Stewart, Mike Raven, David Ryder, Jim Fisher, Jimmy Young, Dave Cash, Kenny Everett, Simon Dee, Terry Wogan, Duncan Johnson, Doug Crawford, Tommy Vance, Chris Denning, Emperor Rosko, Pete Murray, Bob Holness. Many of the most popular pirate radio voices, such as Simon Dee, had only a one-hour slot per week Initially, the station was unpopular with some of its target audience who, it is claimed, disliked the fact that much of its airtime was shared with Radio 2 and that it was less unequivocally aimed at a young audience than the offshore stations, with some DJs such as Jimmy Young being in their 40s.
The fact that it was part of an "establishment" institution such as the BBC was a turn-off for some, needle time restrictions prevented it from playing as many records as offshore stations had. It had limited finances and as in January 1975, suffered disproportionately when the BBC had to make financial cutbacks, strengthening an impression that it was regarded as a lower priority by senior BBC executives. Despite this, it gained massive audiences, becoming the most listened-to station in the world with audiences of over 10 million claimed for some of its shows. In the early-mid-1970s Radio 1 presenters were out of the British tabloids, thanks to the Publicity Department's high-profile work; the touring summer live broadcasts called the Radio 1 Roadshow – as part of the BBC'Radio Weeks' promotions that took Radio 1, 2 and 4 shows on the road – drew some of the largest crowds of the decade. The station undoubtedly played a role in maintaining the high sales of 45 rpm single records although it benefited from a lack of competition, apart from Radio Luxembourg and Manx Radio in the Isle of Man..
Alan Freeman's'Saturday Rock Show' was voted'Best Radio Show' five years running by readers of a national music publication, was axed by controller Derek Chinnery. Annie Nightingale, who joined in 1970, was Britain's first female DJ and is now the longest serving presenter, having evolved her musical tastes with the times. On Thursday 23 November 1978 the station moved to two new medium wave frequencies which allowed a major increase in transmitter powers and improved coverage of the UK. 247 metres was passed to Radio 3. The station was on medium wave only until the early 80s, when it took over the Radio 2 FM frequency for a number of hours on weekend afternoons and late weekday evenings; the BBC set up an FM channel specifically
Streaming media is multimedia, received by and presented to an end-user while being delivered by a provider. The verb "to stream" refers to the process of obtaining media in this manner. A client end-user can use their media player to start playing digital video or digital audio content before the entire file has been transmitted. Distinguishing delivery method from the media distributed applies to telecommunications networks, as most of the delivery systems are either inherently streaming or inherently non-streaming. For example, in the 1930s, elevator music was among the earliest popular music available as streaming media; the term "streaming media" can apply to media other than video and audio, such as live closed captioning, ticker tape, real-time text, which are all considered "streaming text". Live streaming is the delivery of Internet content in real-time much as live television broadcasts content over the airwaves via a television signal. Live internet streaming requires a form of source media, an encoder to digitize the content, a media publisher, a content delivery network to distribute and deliver the content.
Live streaming does not need to be recorded at the origination point, although it is. There are challenges with streaming content on the Internet. If the user does not have enough bandwidth in their Internet connection, they may experience stops, lags, or slow buffering of the content; some users may not be able to stream certain content due to not having compatible computer or software systems. Some popular streaming services include the video sharing website YouTube and Mixer, which live stream the playing of video games. Netflix and Amazon Video stream movies and TV shows, Spotify, Apple Music and TIDAL stream music. In the early 1920s, George O. Squier was granted patents for a system for the transmission and distribution of signals over electrical lines, the technical basis for what became Muzak, a technology streaming continuous music to commercial customers without the use of radio. Attempts to display media on computers date back to the earliest days of computing in the mid-20th century.
However, little progress was made for several decades due to the high cost and limited capabilities of computer hardware. From the late 1980s through the 1990s, consumer-grade personal computers became powerful enough to display various media; the primary technical issues related to streaming were having enough CPU power bus bandwidth to support the required data rates, creating low-latency interrupt paths in the operating system to prevent buffer underrun, enabling skip-free streaming of the content. However, computer networks were still limited in the mid-1990s, audio and video media were delivered over non-streaming channels, such as by downloading a digital file from a remote server and saving it to a local drive on the end user's computer or storing it as a digital file and playing it back from CD-ROMs. In 1991 the first commercial Ethernet Switch was introduced, which enabled more powerful computer networks leading to the first streaming video solutions used by schools and corporations such as expanding Bloomberg Television worldwide.
In the mid 1990s the World Wide Web was established, but streaming audio would not be practical until years later. During the late 1990s and early 2000s, users had increased access to computer networks the Internet. During the early 2000s, users had access to increased network bandwidth in the "last mile"; these technological improvements facilitated the streaming of audio and video content to computer users in their homes and workplaces. There was an increasing use of standard protocols and formats, such as TCP/IP, HTTP, HTML as the Internet became commercialized, which led to an infusion of investment into the sector; the band Severe Tire Damage was the first group to perform live on the Internet. On June 24, 1993, the band was playing a gig at Xerox PARC while elsewhere in the building, scientists were discussing new technology for broadcasting on the Internet using multicasting; as proof of PARC's technology, the band's performance was broadcast and could be seen live in Australia and elsewhere.
In a March 2017 interview, band member Russ Haines stated that the band had used "half of the total bandwidth of the internet" to stream the performance, a 152-by-76 pixel video, updated eight to twelve times per second, with audio quality, "at best, a bad telephone connection". Microsoft Research developed a Microsoft TV application, compiled under MS Windows Studio Suite and tested in conjunction with Connectix QuickCam. RealNetworks was a pioneer in the streaming media markets, when it broadcast a baseball game between the New York Yankees and the Seattle Mariners over the Internet in 1995; the first symphonic concert on the Internet took place at the Paramount Theater in Seattle, Washington on November 10, 1995. The concert was a collaboration between The Seattle Symphony and various guest musicians such as Slash, Matt Cameron, Barrett Martin; when Word Magazine launched in 1995, they featured the first-ever streaming soundtracks on the Internet.

Rock music is a broad genre of popular music that originated as "rock and roll" in the United States in the early 1950s, developed into a range of different styles in the 1960s and particularly in the United Kingdom and in the United States. It has its roots in 1940s and 1950s rock and roll, a style which drew on the genres of blues and blues, from country music. Rock music drew on a number of other genres such as electric blues and folk, incorporated influences from jazz and other musical styles. Musically, rock has centered on the electric guitar as part of a rock group with electric bass and one or more singers. Rock is song-based music with a 4/4 time signature using a verse–chorus form, but the genre has become diverse. Like pop music, lyrics stress romantic love but address a wide variety of other themes that are social or political. By the late 1960s "classic rock" period, a number of distinct rock music subgenres had emerged, including hybrids like blues rock, folk rock, country rock, southern rock, raga rock, jazz-rock, many of which contributed to the development of psychedelic rock, influenced by the countercultural psychedelic and hippie scene.
New genres that emerged included progressive rock. In the second half of the 1970s, punk rock reacted by producing stripped-down, energetic social and political critiques. Punk was an influence in the 1980s on new wave, post-punk and alternative rock. From the 1990s alternative rock began to dominate rock music and break into the mainstream in the form of grunge and indie rock. Further fusion subgenres have since emerged, including pop punk, electronic rock, rap rock, rap metal, as well as conscious attempts to revisit rock's history, including the garage rock/post-punk and techno-pop revivals at the beginning of the 2000s. Rock music has embodied and served as the vehicle for cultural and social movements, leading to major subcultures including mods and rockers in the UK and the hippie counterculture that spread out from San Francisco in the US in the 1960s. 1970s punk culture spawned the goth and emo subcultures. Inheriting the folk tradition of the protest song, rock music has been associated with political activism as well as changes in social attitudes to race and drug use, is seen as an expression of youth revolt against adult consumerism and conformity.
The sound of rock is traditionally centered on the amplified electric guitar, which emerged in its modern form in the 1950s with the popularity of rock and roll. It was influenced by the sounds of electric blues guitarists; the sound of an electric guitar in rock music is supported by an electric bass guitar, which pioneered in jazz music in the same era, percussion produced from a drum kit that combines drums and cymbals. This trio of instruments has been complemented by the inclusion of other instruments keyboards such as the piano, the Hammond organ, the synthesizer; the basic rock instrumentation was derived from the basic blues band instrumentation. A group of musicians performing rock music is termed as a rock group. Furthermore, it consists of between three and five members. Classically, a rock band takes the form of a quartet whose members cover one or more roles, including vocalist, lead guitarist, rhythm guitarist, bass guitarist and keyboard player or other instrumentalist. Rock music is traditionally built on a foundation of simple unsyncopated rhythms in a 4/4 meter, with a repetitive snare drum back beat on beats two and four.
Melodies originate from older musical modes such as the Dorian and Mixolydian, as well as major and minor modes. Harmonies range from the common triad to parallel perfect fourths and fifths and dissonant harmonic progressions. Since the late 1950s and from the mid 1960s onwards, rock music used the verse-chorus structure derived from blues and folk music, but there has been considerable variation from this model. Critics have stressed the eclecticism and stylistic diversity of rock; because of its complex history and its tendency to borrow from other musical and cultural forms, it has been argued that "it is impossible to bind rock music to a rigidly delineated musical definition." Unlike many earlier styles of popular music, rock lyrics have dealt with a wide range of themes, including romantic love, rebellion against "The Establishment", social concerns, life styles. These themes were inherited from a variety of sources such as the Tin Pan Alley pop tradition, folk music, rhythm and blues.
Music journalist Robert Christgau characterizes rock lyrics as a "cool medium" with simple diction and repeated refrains, asserts that rock's primary "function" "pertains to music, or, more noise." The predominance of white and middle class musicians in rock music has been noted, rock has been seen as an appropriation of black musical forms for a young and male audience. As a result, it has been seen to articulate the concerns of this group in both style and lyrics. Christgau, writing in 1972, said in spite of some exceptions, "rock and roll implies an identification of male sexuality and aggression". Since the term "rock" started being used in preference to "rock and roll" from the late-1960s, it has been contrasted with pop music, with which it has shared many characteristics, but from wh
The United Kingdom the United Kingdom of Great Britain and Northern Ireland, sometimes referred to as Britain, is a sovereign country located off the north-western coast of the European mainland. The United Kingdom includes the island of Great Britain, the north-eastern part of the island of Ireland, many smaller islands. Northern Ireland is the only part of the United Kingdom that shares a land border with another sovereign state, the Republic of Ireland. Apart from this land border, the United Kingdom is surrounded by the Atlantic Ocean, with the North Sea to the east, the English Channel to the south and the Celtic Sea to the south-west, giving it the 12th-longest coastline in the world; the Irish Sea lies between Great Ireland. With an area of 242,500 square kilometres, the United Kingdom is the 78th-largest sovereign state in the world, it is the 22nd-most populous country, with an estimated 66.0 million inhabitants in 2017. The UK is constitutional monarchy; the current monarch is Queen Elizabeth II, who has reigned since 1952, making her the longest-serving current head of state.
The United Kingdom's capital and largest city is London, a global city and financial centre with an urban area population of 10.3 million. Other major urban areas in the UK include Greater Manchester, the West Midlands and West Yorkshire conurbations, Greater Glasgow and the Liverpool Built-up Area; the United Kingdom consists of four constituent countries: England, Scotland and Northern Ireland. Their capitals are London, Edinburgh and Belfast, respectively. Apart from England, the countries have their own devolved governments, each with varying powers, but such power is delegated by the Parliament of the United Kingdom, which may enact laws unilaterally altering or abolishing devolution; the nearby Isle of Man, Bailiwick of Guernsey and Bailiwick of Jersey are not part of the UK, being Crown dependencies with the British Government responsible for defence and international representation. The medieval conquest and subsequent annexation of Wales by the Kingdom of England, followed by the union between England and Scotland in 1707 to form the Kingdom of Great Britain, the union in 1801 of Great Britain with the Kingdom of Ireland created the United Kingdom of Great Britain and Ireland.
Five-sixths of Ireland seceded from the UK in 1922, leaving the present formulation of the United Kingdom of Great Britain and Northern Ireland. There are fourteen British Overseas Territories, the remnants of the British Empire which, at its height in the 1920s, encompassed a quarter of the world's land mass and was the largest empire in history. British influence can be observed in the language and political systems of many of its former colonies; the United Kingdom is a developed country and has the world's fifth-largest economy by nominal GDP and ninth-largest economy by purchasing power parity. It has a high-income economy and has a high Human Development Index rating, ranking 14th in the world, it was the world's first industrialised country and the world's foremost power during the 19th and early 20th centuries. The UK remains a great power, with considerable economic, military and political influence internationally, it is sixth in military expenditure in the world. It has been a permanent member of the United Nations Security Council since its first session in 1946.
It has been a leading member state of the European Union and its predecessor, the European Economic Community, since 1973. The United Kingdom is a member of the Commonwealth of Nations, the Council of Europe, the G7, the G20, NATO, the Organisation for Economic Co-operation and Development and the World Trade Organization; the 1707 Acts of Union declared that the kingdoms of England and Scotland were "United into One Kingdom by the Name of Great Britain". The term "United Kingdom" has been used as a description for the former kingdom of Great Britain, although its official name from 1707 to 1800 was "Great Britain"; the Acts of Union 1800 united the kingdom of Great Britain and the kingdom of Ireland in 1801, forming the United Kingdom of Great Britain and Ireland. Following the partition of Ireland and the independence of the Irish Free State in 1922, which left Northern Ireland as the only part of the island of Ireland within the United Kingdom, the name was changed to the "United Kingdom of Great Britain and Northern Ireland".
Although the United Kingdom is a sovereign country, Scotland and Northern Ireland are widely referred to as countries. The UK Prime Minister's website has used the phrase "countries within a country" to describe the United Kingdom; some statistical summaries, such as those for the twelve NUTS 1 regions of the United Kingdom refer to Scotland and Northern Ireland as "regions". Northern Ireland is referred to as a "province". With regard to Northern Ireland, the descriptive name used "can be controversial, with the choice revealing one's political preferences"; the term "Great Britain" conventionally refers to the island of Great Britain, or politically to England and Wales in combination. However, it is sometimes used as a loose synonym for the United Kingdom as a whole; the term "Britain" is used both as a synonym for Great Britain, as a synonym for the United Kingdom. Usage is mixed, with the BBC preferring to use Britain as shorthand only for Great Britain and the UK Government, while accepting that both terms refer to the United K
A music download is the digital transfer of music via the Internet into a device capable of decoding and playing it, such as a home computer, MP3 player or smartphone. This term encompasses both legal downloads and downloads of copyrighted material without permission or legal payment. According to a Nielsen report, downloadable music accounted for 55.9% of all music sales in the US in 2012. By the beginning of 2011, Apple's iTunes Store alone made US$1.1 billion of revenue in the first quarter of its fiscal year. Paid downloads are sometimes encoded with Digital Rights Management that restricts copying the music or playing purchased songs on certain digital audio players, they are always compressed using a lossy codec, which reduces file size and bandwidth requirements. These music resources have been created as a response to expanding technology and needs of customers that wanted easy, quick access to music, their business models respond to the "download revolution" by making legal services attractive for users.
Legal music downloads have faced a number of challenges from artists, record labels and the Recording Industry Association of America. In July 2007, the Universal Music Group decided not to renew their long-term contracts with iTunes; this decision was based upon the issue of pricing of songs, as Universal wanted to be able to charge more or less depending on the artist, a shift away from iTunes' standard—at the time—99 cents per song pricing. Many industry leaders feel that this is only the first of many show-downs between Apple Inc. and the various record labels. According to research by the website TorrentFreak, 38% of Swedish artists support file share downloading and claim that it helps artists in early career stages; the Swedish rock group Lamont has profited from file sharing. The Recording Industry Association of America oversees about 85% of published music production and manufacturing in the United States, they work to protect musicians while supporting the First Amendment rights. Their stated goal is to support artists' creativity and help them not be cheated out of money by illegal downloading.
The Recording Industry Association of America launched its first lawsuits on 8 September 2003, against individuals who illegally downloaded music files from the Kazaa FastTrack network. Two years after it began, the campaign survived at least one major legal challenge; the RIAA said it filed 750 suits in February 2006 against individuals downloading music files without paying for them in hopes of putting an end to Internet music piracy. The RIAA hopes their campaign will force people to respect the copyrights of music labels and minimize the number of illegal downloads; the Official Charts Company began to incorporate downloads in the UK Singles Chart on 17 April 2005, at which time Radio 1 stopped broadcasting the separate download chart, although the chart is still compiled. This was on condition that the song must have a physical media release at the same time. Music downloads have been measured by the Official Charts Company since 2004 and included in the main UK Singles Chart from 2005.
The most downloaded song in the UK is "Happy" by Pharrell Williams with over 1.8 million downloads. In November 2005, the record for the best-selling downloaded single in the United States was held by Gwen Stefani's "Hollaback Girl", which sold over one million downloads, making it the first song to achieve platinum download status; as of July 2012, the record for the best-selling downloaded single in the United States on the iTunes Store is held by The Black Eyed Peas's "I Gotta Feeling", which has sold over 8 million downloads. Soon after his death in 2009, Michael Jackson became the first artist to sell over one million songs downloaded via the Internet in one week. However, Adele marks the most downloads sold by a single song in a week, with "Hello" selling 1.12 million copies in November 2015. Eminem's seventh studio album, became the first album to sell one million digital copies. Beyoncé's self-titled fifth studio album became the fastest-selling album within 24 hours in iTunes history after its release in December 2013.
Within 24 hours of availability, the album sold 430,000 digital copies. Adele's third studio album 25 became the fastest-selling album in a week iTunes history after it was released on 20 November 2015, it sold 1.64 million digital copies in its first week. In 2006, the Recording Industry Association of Japan began issuing certifications for digitally released music in Japan, compiling data from the early 2000s onwards; the best-selling song is Fukushima-based vocal group Greeeen's song "Kiseki", certified for being downloaded four million times between 2008 and 2015, followed by R&B singer Thelma Aoyama's "Soba ni Iru ne" featuring rapper SoulJa, certified for three million downloads between 2008 and 2014. Greeeen's song "Ai Uta" ranks as the third highest certified song, with 2.5 million downloads tracked between 2007 and 2009. Two more songs have sold more than two million paid downloads: Ayaka's "Mikazuki" and Kobukuro's "Tsubomi"; the most successful ringtone in Japan is Moldovan-Romanian band O-Zone's "Dragostea din tei", known locally as "Koi no Maiahi", certified as having four million units sold.
In Japan, only two albums have received digital certifications by the RIAJ. The first was Songs for Japan, a charity compilation album raising profits for the 2011 Tōhoku earthquake and tsunami, certified gold for 100,000 downloa
Heavy metal music
Heavy metal is a genre of rock music that developed in the late 1960s and early 1970s in the United Kingdom. With roots in blues rock, psychedelic rock, acid rock, the bands that created heavy metal developed a thick, massive sound, characterized by amplified distortion, extended guitar solos, emphatic beats, overall loudness; the genre's lyrics and performance styles are sometimes associated with machismo. In 1968, three of the genre's most famous pioneers, Led Zeppelin, Black Sabbath and Deep Purple were founded. Though they came to attract wide audiences, they were derided by critics. During the mid-1970s, Judas Priest helped spur the genre's evolution by discarding much of its blues influence. Beginning in the late 1970s, bands in the new wave of British heavy metal such as Iron Maiden and Def Leppard followed in a similar vein. Before the end of the decade, heavy metal fans became known as "metalheads" or "headbangers". During the 1980s, glam metal became popular with groups such as Mötley Crüe.
Underground scenes produced an array of more aggressive styles: thrash metal broke into the mainstream with bands such as Metallica, Slayer and Anthrax, while other extreme subgenres of heavy metal such as death metal and black metal remain subcultural phenomena. Since the mid-1990s popular styles have further expanded the definition of the genre; these include groove metal and nu metal, the latter of which incorporates elements of grunge and hip hop. Heavy metal is traditionally characterized by loud distorted guitars, emphatic rhythms, dense bass-and-drum sound, vigorous vocals. Heavy metal subgenres variously alter, or omit one or more of these attributes; the 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, a singer, who may or may not be an instrumentalist.
Keyboard instruments are sometimes used to enhance the fullness of the sound. Deep Purple's Jon Lord played an overdriven Hammond organ. In 1970, John Paul Jones used a Moog synthesizer on Led Zeppelin III; the electric guitar and the sonic power that it projects through amplification has been the key element in heavy metal. The heavy metal guitar sound comes from a combined use of heavy distortion. For classic heavy metal guitar tone, guitarists maintain moderate levels gain at moderate levels, without excessive preamp or pedal distortion, to retain open spaces and air in the music. Thrash metal guitar tone has scooped mid-frequencies and compressed sound with lots of bass frequencies. Guitar solos are "an essential element of the heavy metal code... that underscores the significance of the guitar" to the genre. Most heavy metal songs "feature at least one guitar solo", "a primary means through which the heavy metal performer expresses virtuosity"; some exceptions are nu grindcore bands, which tend to omit guitar solos.
With rhythm guitar parts, the "heavy crunch sound in heavy metal... palm muting" the strings with the picking hand and using distortion. Palm muting creates a tighter, more precise sound and it emphasizes the low end; the lead role of the guitar in heavy metal 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 claims; the prominent role of the bass is key to the metal sound, the interplay of bass and guitar is a central element. The bass guitar provides the low-end sound crucial to making the music "heavy"; the bass plays a "more important role in heavy metal than in any other genre of rock". Metal basslines vary in complexity, from holding down a low pedal point as a foundation to doubling complex riffs and licks along with the lead or rhythm guitars.
Some bands feature the bass as a lead instrument, an approach popularized by Metallica's Cliff Burton with his heavy emphasis on bass guitar solos and use of chords while playing bass in the early 1980s. Lemmy of Motörhead played overdriven power chords in his bass lines; the essence of heavy metal drumming is creating a loud, constant beat for the band using the "trifecta of speed and precision". Heavy metal drumming "requires an exceptional amount of endurance", drummers have to develop "considerable speed and dexterity... to play the intricate patterns" used in heavy metal. A characteristic metal drumming technique is the cymbal choke, which consists of striking a cymbal and immediately silencing it by grabbing it with the other hand, producing a burst of sound; the metal drum setup is much larger than those employed in other forms of rock music. Black metal, death metal and some "mainstream metal" bands "all depend upon double-kicks and blast beats". In live performance, loudness—an "onslaught of sound", in sociologist Deena Weinstein's description—is considered vital.
In his book Metalheads, psychologist Jeffrey Arnett refers to heavy me
