Loures is a city and a municipality in the central Portuguese Grande Lisboa Subregion. It is situated to the north of Lisbon, it was created on 26 July 1886 by a royal decree. The population in 2011 was 199,494, in an area of 167.24 km². It borders the municipalities of Odivelas, Mafra, Arruda dos Vinhos, Vila Franca de Xira and Lisbon; the municipality is divided in three areas: the rustic one, to the north, the urban one, to the south and the urban-industrial, to the east. Portela de Sacavém is the site of Portugal's largest airport. In this eastern area, the ten local parishes claim to be independent from Loures, form its own municipality set in the town of Sacavém; this struggle dates from the beginnings of the Portuguese Republic, has a strong support among the local population. There was early human settlement in the Loures area dating back to the Upper Paleolithic period, as evidenced by findings at the Cave of Pego do Diabo and the Cave of Salemas. Several Neolithic burial chambers have been identified, such as the Anta de Carcavelos.
Loures was a Roman settlement during the 1st millennium, based in a cemetery that became the site of the first church. It was a region notable for the presence of many castros, before the Roman occupation. After the Romans, the Visigoths began occupying the territory, followed by the Moors; the parish of Loures was first mentioned in 1118, again in 1191, along with the parishes of Unhose and Sacavém. At the time the region was agricultural, involved in small export trade, that included the cultivation of lettuce; the first written document appeared in 1170, written by Afonso Henriques, who provided privileges and benefits to the Moors that lived on the outskirts of Lisbon in the sallayos. In 1178, King Sancho I of Portugal having discovered that the Moors of Lisbon were allied to groups in Loures, came to the territory with a Templar force to confront those peoples. Following the defeat of the Moors, the King transferred the region to the Knights Templar, who established the sect of warrior-monks.
The extinction of Templars in 1311, opened the way for the expropriation of lands and property by the Pope. King Denis of Portugal, on the other hand, proposed the creation in Portugal of a new Order to replace the Templars that would be the recipient of these assets: the Order of Christ. In Loures, the Templar lands passed into the hands of this religious order constructing a new Church over the ruins of the 4th-century temple, located alongside the Christian cemetery that existed there. In addition to the main settlement, the village of Montemor, situated at a height of 350 metres, was sought by residents from Lisbon during the Plague; the Chapel of Nossa Senhora da Saúde was built during this era: in 1598, the Plague devastated the capital, for five years on it spread across the country. Fleeing the contagion, many of urban residents escaped into the country to the elevated villages, which they assumed protected them from the disease; some families brought with them the image of Our Lady of Health, raised a church, in order to defend themselves of the Plague: by 1604 the threat had passed, no cases of the disease were discovered within the territory.
A myth developed for successive generations of the miraculous influence of the patron, providing protection from health-related disease. By the 19th century, between 1832 and 1834, cholera spread throughout the region, the people of Loures, once again, implored Our Lady of Health to protect them from epidemic. Owing to their fears, the image of the saint was removed from Montemor, paraded through Loures in procession, it remained in the altar of the Church of Loures until the threat had passed, when it was returned to its hermitage in Montemor. Loures was elevated to the status of "town" on 26 October 1926, under decree 12/543, city on 9 August 1990, under decree 35/90. In 1997 Odivelas and six other parishes were separated to form Odivelas Municipality. Administratively, the municipality is divided into 10 civil parishes: Bucelas Camarate, Unhos e Apelação Fanhões Loures Lousa Moscavide e Portela Sacavém e Prior Velho Santa Iria de Azoia São João da Talha e Bobadela Santo Antão e São Julião do Tojal Santo António dos Cavaleiros e FrielasFrom these, both Loures and Sacavém are cities, Bobadela, Camarate, Santa Iria de Azóia, Santo António dos Cavaleiros and São João da Talha are towns.

Singing is the act of producing musical sounds with the voice and augments regular speech by the use of sustained tonality, a variety of vocal techniques. A person who sings is called a vocalist. Singers perform music that can be sung without accompaniment by musical instruments. Singing is done in an ensemble of musicians, such as a choir of singers or a band of instrumentalists. Singers may perform as soloists or accompanied by anything from a single instrument up to a symphony orchestra or big band. Different singing styles include art music such as opera and Chinese opera, Indian music and religious music styles such as gospel, traditional music styles, world music, blues and popular music styles such as pop, electronic dance music and filmi. Singing arranged or improvised, it may be done as a form of religious devotion, as a hobby, as a source of pleasure, comfort or ritual, as part of music education or as a profession. Excellence in singing requires time, dedication and regular practice.
If practice is done on a regular basis the sounds can become more clear and strong. Professional singers build their careers around one specific musical genre, such as classical or rock, although there are singers with crossover success, they take voice training provided by voice teachers or vocal coaches throughout their careers. In its physical aspect, singing has a well-defined technique that depends on the use of the lungs, which act as an air supply or bellows. Though these four mechanisms function independently, they are coordinated in the establishment of a vocal technique and are made to interact upon one another. During passive breathing, air is inhaled with the diaphragm while exhalation occurs without any effort. Exhalation may be aided by lower pelvis/pelvic muscles. Inhalation is aided by use of external intercostals and sternocleidomastoid muscles; the pitch is altered with the vocal cords. With the lips closed, this is called humming; the sound of each individual's singing voice is unique not only because of the actual shape and size of an individual's vocal cords but due to the size and shape of the rest of that person's body.
Humans have vocal folds which can loosen, tighten, or change their thickness, over which breath can be transferred at varying pressures. The shape of the chest and neck, the position of the tongue, the tightness of otherwise unrelated muscles can be altered. Any one of these actions results in a change in pitch, timbre, or tone of the sound produced. Sound resonates within different parts of the body and an individual's size and bone structure can affect the sound produced by an individual. Singers can learn to project sound in certain ways so that it resonates better within their vocal tract; this is known as vocal resonation. Another major influence on vocal sound and production is the function of the larynx which people can manipulate in different ways to produce different sounds; these different kinds of laryngeal function are described as different kinds of vocal registers. The primary method for singers to accomplish this is through the use of the Singer's Formant, it has been shown that a more powerful voice may be achieved with a fatter and fluid-like vocal fold mucosa.
The more pliable the mucosa, the more efficient the transfer of energy from the airflow to the vocal folds. Vocal registration refers to the system of vocal registers within the voice. A register in the voice is a particular series of tones, produced in the same vibratory pattern of the vocal folds, possessing the same quality. Registers originate in laryngeal function, they occur. Each of these vibratory patterns appears within a particular range of pitches and produces certain characteristic sounds; the occurrence of registers has been attributed to effects of the acoustic interaction between the vocal fold oscillation and the vocal tract. The term "register" can be somewhat confusing; the term register can be used to refer to any of the following: A particular part of the vocal range such as the upper, middle, or lower registers. A resonance area such as chest voice or head voice. A phonatory process A certain vocal timbre or vocal "color" A region of the voice, defined or delimited by vocal breaks.
In linguistics, a register language is a language which combines tone and vowel phonation into a single phonological system. Within speech pathology, the term vocal register has three constituent elements: a certain vibratory pattern of the vocal folds, a certain series of pitches, a certain type of sound. Speech pathologists identify four vocal registers based on the physiology of laryngeal function: the vocal fry register, the modal register, the falsetto register, the whistle register; this view is adopted by many vocal pedagogues. Vocal resonation is the process by which the basic product of phonation is en
The bass guitar is a plucked string instrument similar in appearance and construction to an electric guitar, except with a longer neck and scale length, four to six strings or courses. The four-string bass is tuned the same as the double bass, which corresponds to pitches one octave lower than the four lowest-pitched strings of a guitar, it is played with the fingers or thumb, or striking with a pick. The electric bass guitar has pickups and must be connected to an amplifier and speaker to be loud enough to compete with other instruments. Since the 1960s, the bass guitar has replaced the double bass in popular music as the bass instrument in the rhythm section. While types of basslines vary from one style of music to another, the bassist plays a similar role: anchoring the harmonic framework and establishing the beat. Many styles of music include the bass guitar, it is a soloing instrument. According to the New Grove Dictionary of Music and Musicians, an "Electric bass guitar a Guitar with four heavy strings tuned E1'-A1'-D2-G2."
It defines bass as "Bass. A contraction of Double bass or Electric bass guitar." According to some authors the proper term is "electric bass". Common names for the instrument are "bass guitar", "electric bass guitar", "electric bass" and some authors claim that they are accurate; the bass guitar is a transposing instrument, as it is notated in bass clef an octave higher than it sounds. In the 1930s, musician and inventor Paul Tutmarc of Seattle, developed the first electric bass guitar in its modern form, a fretted instrument designed to be played horizontally; the 1935 sales catalog for Tutmarc's electronic musical instrument company, featured his "Model 736 Bass Fiddle", a four-stringed, solid-bodied, fretted electric bass guitar with a 30 1⁄2-inch scale length, a single pick up. The adoption of a guitar's body shape made the instrument easier to hold and transport than any of the existing stringed bass instruments; the addition of frets enabled bassists to play in tune more than on fretless acoustic or electric upright basses.
Around 100 of these instruments were made during this period. Audiovox sold their “Model 236” bass amplifier. Around 1947, Tutmarc's son, began marketing a similar bass under the Serenader brand name, prominently advertised in the nationally distributed L. D. Heater Music Company wholesale jobber catalogue of 1948. However, the Tutmarc family inventions did not achieve market success. In the 1950s, Leo Fender and George Fullerton developed the first mass-produced electric bass guitar; the Fender Electric Instrument Manufacturing Company began producing the Precision Bass in October 1951. The "P-bass" evolved from a simple, un-contoured "slab" body design and a single coil pickup similar to that of a Telecaster, to something more like a Fender Stratocaster, with a contoured body design, edges beveled for comfort, a split single coil pickup; the "Fender Bass" was a revolutionary new instrument for gigging musicians. In comparison with the large, heavy upright bass, the main bass instrument in popular music from the early 1900s to the 1940s, the bass guitar could be transported to shows.
When amplified, the bass guitar was less prone than acoustic basses to unwanted audio feedback. In 1953 Monk Montgomery became the first bassist to tour with the Fender bass guitar, in Lionel Hampton's postwar big band. Montgomery was possibly the first to record with the bass guitar, on July 2, 1953 with The Art Farmer Septet. Roy Johnson, Shifty Henry, were other early Fender bass pioneers. Bill Black, playing with Elvis Presley, switched from upright bass to the Fender Precision Bass around 1957; the bass guitar was intended to appeal to guitarists as well as upright bass players, many early pioneers of the instrument, such as Carol Kaye, Joe Osborn, Paul McCartney were guitarists. In 1953, following Fender's lead, Gibson released the first short-scale violin-shaped electric bass, with an extendable end pin so a bassist could play it upright or horizontally. Gibson renamed the bass the EB-1 in 1958. In 1958, Gibson released the maple arched-top EB-2 described in the Gibson catalogue as a "hollow-body electric bass that features a Bass/Baritone pushbutton for two different tonal characteristics".
In 1959 these were followed by the more conventional-looking EB-0 Bass. The EB-0 was similar to a Gibson SG in appearance. Whereas Fender basses had pickups mounted in positions in between the base of the neck and the top of the bridge, many of Gibson's early basses featured one humbucking pickup mounted directly against the neck pocket; the EB-3, introduced in 1961 had a "mini-humbucker" at the bridge position. Gibson basses tended to be smaller, sleeker instruments with a shorter scale length than the Precision. A number of other companies began manufacturing bass guitars during the 1950s: Kay in 1952, Hofner and Danelectro in 1956, Rickenbacker in 1957 and Burns/Supersound in 1958. 1956 saw the appearance at the German trade fair "Musikmesse Frankfurt" of the distinctive Höfner 500/1 violin-shaped bass made using violin construction techniques by Walter Höfner, a second-generation violin luthier. The design was known popularly as the "Beat
A drum kit — called a drum set, trap set, or drums — is a collection of drums and other percussion instruments cymbals, which are set up on stands to be played by a single player, with drumsticks held in both hands, the feet operating pedals that control the hi-hat cymbal and the beater for the bass drum. A drum kit consists of a mix of drums and idiophones – most cymbals, but can include the woodblock and cowbell. In the 2000s, some kits include electronic instruments. Both hybrid and electronic kits are used. A standard modern kit, as used in popular music and taught in music schools, contains: A snare drum, mounted on a stand, placed between the player's knees and played with drum sticks A bass drum, played by a pedal operated by the right foot, which moves a felt-covered beater One or more toms, played with sticks or brushes A hi-hat, played with the sticks and closed with left foot pedal One or more cymbals, mounted on stands, played with the sticksAll of these are classified as non-pitched percussion, allowing the music to be scored using percussion notation, for which a loose semi-standardized form exists for both the drum kit and electronic drums.
The drum kit is played while seated on a stool known as a throne. While many instruments like the guitar or piano are capable of performing melodies and chords, most drum kits are unable to achieve this as they produce sounds of indeterminate pitch; the drum kit is a part of the standard rhythm section, used in many types of popular and traditional music styles, ranging from rock and pop to blues and jazz. Other standard instruments used in the rhythm section include the piano, electric guitar, electric bass, keyboards. Many drummers extend their kits from this basic configuration, adding more drums, more cymbals, many other instruments including pitched percussion. In some styles of music, particular extensions are normal. For example, some rock and heavy metal drummers make use of double bass drums, which can be achieved with either a second bass drum or a remote double foot pedal; some progressive drummers may include orchestral percussion such as gongs and tubular bells in their rig. Some performers, such as some rockabilly drummers, play small kits that omit elements from the basic setup.
Before the development of the drum set and cymbals used in military and orchestral music settings were played separately by different percussionists. In the 1840s, percussionists began to experiment with foot pedals as a way to enable them to play more than one instrument, but these devices would not be mass-produced for another 75 years. By the 1860s, percussionists started combining multiple drums into a set; the bass drum, snare drum and other percussion instruments were all struck with hand-held drum sticks. Drummers in musical theater shows and stage shows, where the budget for pit orchestras was limited, contributed to the creation of the drum set by developing techniques and devices that would enable them to cover the roles of multiple percussionists. Double-drumming was developed to enable one person to play the bass and snare with sticks, while the cymbals could be played by tapping the foot on a "low-boy". With this approach, the bass drum was played on beats one and three. While the music was first designed to accompany marching soldiers, this simple and straightforward drumming approach led to the birth of ragtime music when the simplistic marching beats became more syncopated.
This resulted in dance feel. The drum set was referred to as a "trap set", from the late 1800s to the 1930s, drummers were referred to as "trap drummers". By the 1870s, drummers were using an "overhang pedal". Most drummers in the 1870s preferred to do double drumming without any pedal to play multiple drums, rather than use an overhang pedal. Companies patented their pedal systems such as Dee Dee Chandler of New Orleans 1904–05. Liberating the hands for the first time, this evolution saw the bass drum played with the foot of a standing percussionist; the bass drum became the central piece around which every other percussion instrument would revolve. William F. Ludwig, Sr. and his brother, Theobald Ludwig, founded the Ludwig & Ludwig Co. in 1909 and patented the first commercially successful bass drum pedal system, paving the way for the modern drum kit. Wire brushes for use with drums and cymbals were introduced in 1912; the need for brushes arose due to the problem of the drum sound overshadowing the other instruments on stage.
Drummers began using metal fly swatters to reduce the volume on stage next to the other acoustic instruments. Drummers could still play the rudimentary snare figures and grooves with brushes that they would play with drumsticks. By World War I, drum kits were marching band-style military bass drums with many percussion items suspended on and around them. Drum kits became a central part of jazz Dixieland; the modern drum kit was developed in the vaudeville era during the 1920s in New Orleans. In 1917, a New Orleans band called "The Original Dixieland Jazz Band " recorded jazz tunes that became hits all o
A guitarist is a person who plays the guitar. Guitarists may play a variety of guitar family instruments such as classical guitars, acoustic guitars, electric guitars, bass guitars; some guitarists accompany themselves on the guitar by playing the harmonica. The guitarist may employ any of several methods for sounding the guitar, including finger picking, depending on the type of strings used, including strumming with the fingers, or a guitar pick made of bone, plastic, felt, leather, or paper, melodic flatpicking and finger-picking; the guitarist may employ various methods for selecting notes and chords, including fingering, the barre, and'bottleneck' or steel-guitar slides made of glass or metal. These left- and right-hand techniques may be intermixed in performance. Several magazines and websites have compiled what they intend as lists of the greatest guitarists—for example The 100 Greatest Guitarists of All Time by Rolling Stone magazine, or 100 Greatest Guitarists of All Time by Guitar World magazine.
Rolling Stone In 2003, Rolling Stone magazine published a list called The 100 Greatest Guitarists of All Time. This list included 100 guitarists whom the magazine editor David Fricke considered the best, with a brief introduction for each of them; the first in this list is the American guitarist Jimi Hendrix introduced by Pete Townshend, guitarist for The Who, who was, in his turn, ranked at #50 in the list. In describing the list to readers, Paul MacInnes from British newspaper The Guardian wrote, "Surprisingly enough for an American magazine, the top 10 is fair jam-packed with Yanks," though he noted three exceptions in the top 10; the online magazine Blogcritics criticized the list for introducing some undeserving guitarists while forgetting some artists the writer considered more worthy, such as Johnny Marr, Al Di Meola, Phil Keaggy or John Petrucci. In 2011, Rolling Stone updated the list, which this time was chosen by a panel of guitarists and other experts with the top 5 consisting of Jimi Hendrix, Eric Clapton, Jimmy Page, Keith Richards and Jeff Beck.
Artists who had not been included in the previous list were added. Rory Gallagher, for example, was ranked in 57th place; the 100 Greatest Guitarists of All Time is mentioned in many biographies about artists who appear in the list. Guitar World Guitar World, a monthly music magazine devoted to the guitar published their list of 100 greatest guitarists in the book Guitar World Presents the 100 Greatest Guitarists of All Time from the Pages of Guitar World Magazine. Different from the Rolling Stone list, which listed guitarists in descending order, Guitar World divided guitarists by music genre—such as "Lords of Hard Rock" for hard rock artists or "Jazzmen" for jazz players. Despite the appearance in other magazines like Billboard, this publication by Guitar World was criticized for including no female musicians within its selection. However, Guitar World published a list of "Eight Amazing Female Acoustic Players," including Kaki King, Muriel Anderson and Sharon Isbin. TIME and others Following the death of Les Paul, TIME website presented their list of 10 greatest artists in electric guitar.
As in Rolling Stone magazine's list, Jimi Hendrix was chosen as the greatest guitarist followed by Slash from Guns'N' Roses, B. B. King, Keith Richards, Jimmy Page, Eric Clapton. Gigwise.com, an online music magazine ranks Jimi Hendrix as the greatest guitarist followed by Jimmy Page, B. B. King, Keith Richards and Kirk Hammett. There are many classical guitarists listed as notable in their respective epochs. In recent decades, the most "notable classical and cross genre" guitarist was Paco de Lucía, one of the first flamenco guitarists to have crossed over into other genres of music such as classical and jazz. Richard Chapman and Eric Clapton, authors of Guitar: Music, Players, describe de Lucía as a "titanic figure in the world of flamenco guitar", Dennis Koster, author of Guitar Atlas, has referred to de Lucía as "one of history's greatest guitarists.".

Psychedelic rock is a diverse style of rock music inspired, influenced, or representative of psychedelic culture, centred around perception-altering hallucinogenic drugs. The music is intended to replicate and enhance the mind-altering experiences of psychedelic drugs, most notably LSD. Many psychedelic groups differ in style, the label is applied spuriously. Originating in the mid-1960s among British and American musicians, the sounds of psychedelic rock invokes three core effects of LSD: depersonalization and dynamization. Musically, the effects may be represented via novelty studio tricks, electronic or non-Western instrumentation, disjunctive song structures, extended instrumental segments; some of the earlier 1960s psychedelic rock musicians were based in folk and the blues, while others showcased an explicit Indian classical influence called "raga rock". In the 1960s, there existed two main variants of the genre: the whimsical British pop-psychedelia and the harder American West Coast acid rock.
While "acid rock" is sometimes deployed interchangeably with the term "psychedelic rock", it refers more to the heavier and more extreme ends of the genre. The peak years of psychedelic rock were between 1966 and 1969, with milestone events including the 1967 Summer of Love and the 1969 Woodstock Rock Festival, becoming an international musical movement associated with a widespread counterculture before beginning a decline as changing attitudes, the loss of some key individuals and a back-to-basics movement, led surviving performers to move into new musical areas; the genre bridged the transition from early blues and folk-based rock to progressive rock and hard rock, as a result contributed to the development of sub-genres such as heavy metal. Since the late 1970s it has been revived in various forms of neo-psychedelia; as a musical style, psychedelic rock attempted to replicate the effects of and enhance the mind-altering experiences of hallucinogenic drugs, incorporating new electronic sound effects and recording effects, extended solos, improvisation.
Common features include: electric guitars used with feedback, wah wah and fuzzbox effects units. The term "psychedelic" was coined in 1956 by psychiatrist Humphry Osmond first as an alternative descriptor for hallucinogenic drugs in the context of psychedelic psychotherapy; as the countercultural scene developed in San Francisco, the terms acid rock and psychedelic rock were used in 1966 to describe the new drug-influenced music and were being used by 1967. The terms psychedelic rock and acid rock are used interchangeably, but acid rock may be distinguished as a more extreme variation, heavier, relied on long jams, focused more directly on LSD, made greater use of distortion. In the popular music of the early 1960s, it was common for producers and engineers to experiment with musical form, unnatural reverb, other sound effects; some of the best known examples are Phil Spector's Wall of Sound production formula and Joe Meek's use of homemade electronics for acts like the Tornados. XTC's Andy Partridge interprets the music of psychedelic groups as a "grown-up" version of children's novelty records, believing that many acts were trying to emulate those records that they grew up with.
There was no transition to be made. You go from things like'Flying Purple People Eater' to'I Am the Walrus', they go hand-in-hand." Music critic Richie Unterberger says that attempts to "pin down" the first psychedelic record are therefore "nearly as elusive as trying to name the first rock & roll record". Some of the "far-fetched claims" include the instrumental "Telstar" and the Dave Clark Five's "massively reverb-laden" "Any Way You Want It"; the first mention of LSD on a rock record was the Gamblers' 1960 surf instrumental "LSD 25". A 1962 single by The Ventures, "The 2000 Pound Bee", issued forth the buzz of a distorted, "fuzztone" guitar, the quest into "the possibilities of heavy, transistorised distortion" and other effects, like improved reverb and echo began in earnest on London's fertile rock'n' roll scene. By 1964 fuzztone could be heard on singles by P. J. Proby, the Beatles had employed feedback in "I Feel Fine", their 6th consecutive No. 1 hit in the UK. American folk singer Bob Dylan was a massive influence on mid 1960s rock music.
He led directly to the creation of folk rock and the psychedelic rock musicians that followed, his lyrics were a touchstone for the psychedelic songwriters of the late 1960s. Virtuoso sitarist Ravi Shankar had begun in 1956 a mission to bring Indian classical music to the West, inspiring jazz and folk musicians.
In the music industry, a single is a type of release a song recording of fewer tracks than an LP record or an album. This can be released for sale to the public in a variety of different formats. In most cases, a single is a song, released separately from an album, although it also appears on an album; these are the songs from albums that are released separately for promotional uses such as digital download or commercial radio airplay and are expected to be the most popular. In other cases a recording released. Despite being referred to as a single, singles can include up to as many as three tracks; the biggest digital music distributor, iTunes Store, accepts as many as three tracks less than ten minutes each as a single, as does popular music player Spotify. Any more than three tracks on a musical release or thirty minutes in total running time is either an extended play or, if over six tracks long, an album; when mainstream music was purchased via vinyl records, singles would be released double-sided.
That is to say, they were released with an A-side and B-side, on which two singles would be released, one on each side. Moreover, only the most popular songs from a released album would be released as a single. In more contemporary forms of music consumption, artists release most, if not all, of the tracks on an album as singles; the basic specifications of the music single were set in the late 19th century, when the gramophone record began to supersede phonograph cylinders in commercially produced musical recordings. Gramophone discs were manufactured in several sizes. By about 1910, the 10-inch, 78 rpm shellac disc had become the most used format; the inherent technical limitations of the gramophone disc defined the standard format for commercial recordings in the early 20th century. The crude disc-cutting techniques of the time and the thickness of the needles used on record players limited the number of grooves per inch that could be inscribed on the disc surface, a high rotation speed was necessary to achieve acceptable recording and playback fidelity.
78 rpm was chosen as the standard because of the introduction of the electrically powered, synchronous turntable motor in 1925, which ran at 3600 rpm with a 46:1 gear ratio, resulting in a rotation speed of 78.26 rpm. With these factors applied to the 10-inch format and performers tailored their output to fit the new medium; the 3-minute single remained the standard into the 1960s, when the availability of microgroove recording and improved mastering techniques enabled recording artists to increase the duration of their recorded songs. The breakthrough came with Bob Dylan's "Like a Rolling Stone". Although CBS tried to make the record more "radio friendly" by cutting the performance into halves, separating them between the two sides of the vinyl disc, both Dylan and his fans demanded that the full six-minute take be placed on one side, that radio stations play the song in its entirety; as digital downloading and audio streaming have become more prevalent, it has become possible for every track on an album to be available separately.
The concept of a single for an album has been retained as an identification of a more promoted or more popular song within an album collection. The demand for music downloads skyrocketed after the launch of Apple's iTunes Store in January 2001 and the creation of portable music and digital audio players such as the iPod. In September 1997, with the release of Duran Duran's "Electric Barbarella" for paid downloads, Capitol Records became the first major label to sell a digital single from a well-known artist. Geffen Records released Aerosmith's "Head First" digitally for free. In 2004, Recording Industry Association of America introduced digital single certification due to significant sales of digital formats, with Gwen Stefani's "Hollaback Girl" becoming RIAA's first platinum digital single. In 2013, RIAA incorporated on-demand streams into the digital single certification. Single sales in the United Kingdom reached an all-time low in January 2005, as the popularity of the compact disc was overtaken by the then-unofficial medium of the music download.
Recognizing this, On 17 April 2005, Official UK Singles Chart added the download format to the existing format of physical CD singles. Gnarls Barkley was the first act to reach No.1 on this chart through downloads alone in April 2006, for their debut single "Crazy", released physically the following week. On 1 January 2007 digital downloads became eligible from the point of release, without the need for an accompanying physical. Sales improved in the following years, reaching a record high in 2008 that still proceeded to be overtaken in 2009, 2010 and 2011. Singles have been issued in various formats, including 7-inch, 10-inch, 12-inch vinyl discs. Other, less common, formats include singles on Digital Compact Cassette, DVD, LD, as well as many non-standard sizes of vinyl disc; the most common form of the vinyl single is the 45 or 7-inch. The names are derived from its play speed, 45 rpm, the standard diameter, 7 inches; the 7-inch 45 rpm record was released 31 March 1949 by RCA Victor as a smaller, more durable and higher-fidelity replacement for the 78 rpm shellac discs.
The first 45
