California is a state in the Pacific Region of the United States. With 39.6 million residents, California is the most populous U. S. the third-largest by area. The state capital is Sacramento; the Greater Los Angeles Area and the San Francisco Bay Area are the nation's second and fifth most populous urban regions, with 18.7 million and 9.7 million residents respectively. Los Angeles is California's most populous city, the country's second most populous, after New York City. California has the nation's most populous county, Los Angeles County, its largest county by area, San Bernardino County; the City and County of San Francisco is both the country's second-most densely populated major city after New York City and the fifth-most densely populated county, behind only four of the five New York City boroughs. California's $3.0 trillion economy is larger than that of any other state, larger than those of Texas and Florida combined, the largest sub-national economy in the world. If it were a country, California would be the 5th largest economy in the world, the 36th most populous as of 2017.
The Greater Los Angeles Area and the San Francisco Bay Area are the nation's second- and third-largest urban economies, after the New York metropolitan area. The San Francisco Bay Area PSA had the nation's highest GDP per capita in 2017 among large PSAs, is home to three of the world's ten largest companies by market capitalization and four of the world's ten richest people. California is considered a global trendsetter in popular culture, innovation and politics, it is considered the origin of the American film industry, the hippie counterculture, fast food, the Internet, the personal computer, among others. The San Francisco Bay Area and the Greater Los Angeles Area are seen as global centers of the technology and entertainment industries, respectively. California has a diverse economy: 58% of the state's economy is centered on finance, real estate services and professional, scientific and technical business services. Although it accounts for only 1.5% of the state's economy, California's agriculture industry has the highest output of any U.
S. state. California is bordered by Oregon to the north and Arizona to the east, the Mexican state of Baja California to the south; the state's diverse geography ranges from the Pacific Coast in the west to the Sierra Nevada mountain range in the east, from the redwood–Douglas fir forests in the northwest to the Mojave Desert in the southeast. The Central Valley, a major agricultural area, dominates the state's center. Although California is well-known for its warm Mediterranean climate, the large size of the state results in climates that vary from moist temperate rainforest in the north to arid desert in the interior, as well as snowy alpine in the mountains. Over time and wildfires have become more pervasive features. What is now California was first settled by various Native Californian tribes before being explored by a number of European expeditions during the 16th and 17th centuries; the Spanish Empire claimed it as part of Alta California in their New Spain colony. The area became a part of Mexico in 1821 following its successful war for independence but was ceded to the United States in 1848 after the Mexican–American War.
The western portion of Alta California was organized and admitted as the 31st state on September 9, 1850. The California Gold Rush starting in 1848 led to dramatic social and demographic changes, with large-scale emigration from the east and abroad with an accompanying economic boom; the word California referred to the Baja California Peninsula of Mexico. The name derived from the mythical island California in the fictional story of Queen Calafia, as recorded in a 1510 work The Adventures of Esplandián by Garci Rodríguez de Montalvo; this work was the fifth in a popular Spanish chivalric romance series that began with Amadis de Gaula. Queen Calafia's kingdom was said to be a remote land rich in gold and pearls, inhabited by beautiful black women who wore gold armor and lived like Amazons, as well as griffins and other strange beasts. In the fictional paradise, the ruler Queen Calafia fought alongside Muslims and her name may have been chosen to echo the title of a Muslim leader, the Caliph. It's possible.
Know ye that at the right hand of the Indies there is an island called California close to that part of the Terrestrial Paradise, inhabited by black women without a single man among them, they lived in the manner of Amazons. They were robust of body with great virtue; the island itself is one of the wildest in the world on account of the craggy rocks. Shortened forms of the state's name include CA, Cal. Calif. and US-CA. Settled by successive waves of arrivals during the last 10,000 years, California was one of the most culturally and linguistically diverse areas in pre-Columbian North America. Various estimates of the native population range from 100,000 to 300,000; the Indigenous peoples of California included more than 70 distinct groups of Native Americans, ranging from large, settled populations living on the coast to groups in the interior. California groups were diverse in their political organization with bands, villages, on the resource-rich coasts, large chiefdoms, such as the Chumash and Salinan.

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
Red Lorry Yellow Lorry
Red Lorry Yellow Lorry known briefly as the Lorries, are a post-punk band that were formed in Leeds, England in early 1981. The band was formed by guitarist/songwriter Chris Reed and vocalist Mark Sweeney, along with bassist Steve Smith and drummer Mick Brown. Sweeney left the band in late 1981 and Reed permanently took over as vocalist, with Martin Fagan joining as a second guitarist; the group's sound, featuring a numbing guitar drone, powerfully throbbing bass, pounding drum machine, Reed's cavernous vocal tones, caused the Lorries to be lumped into the then-developing gothic rock scene by pop journalists, although the band themselves denied they were associated with goth and preferred to cite Wire as an influence, said they "were inspired by MC5."In 1982, the Lorries' manager Dave Hall provided independent record label Red Rhino with a cassette of the group's demos. Impressed by the quality of the songs, Red Rhino label head "Tony K" signed the band and released "Beating My Head" unchanged from the demo as the band's debut single.
The song made a strong appearance on the influential NME independent record chart. Fagan and Smith soon departed the band, to be replaced by Dave Wolfenden and Paul Southern respectively. Afterwards, bassist Southern was replaced by Leon Phillips. While numerous additional personnel changes would occur in the history of the band, Wolfenden became a mainstay and a frequent songwriting partner of Reed's during the band's most productive period. In 1983 and 1984, the band released several more singles. John Peel was an early supporter, the band recorded two radio sessions for him in March and November 1983. In 1985, the band's debut album, Talk about the Weather, was released and peaked at No. 3 on the NME independent albums chart. The album, which most fans consider to be the band's best, received positive reviews and sold well for a small label offering. "Hollow Eyes", a single taken from the album, attained good sales as well, as did follow-up non-LP singles "Chance" and "Spinning Round", the latter of, felt to be the Lorries's strongest song.
The band released one more album on Red Rhino in 1986, a single and a four track EP, before signing to Situation Two, an offshoot of Beggars Banquet Records. Two albums followed, 1989's Blow. Neither of the Beggars Banquet albums appeared on any mainstream pop charts. Singles, including "Only Dreaming" and "Open Up" failed to chart, the band was subsequently dropped by the label. In 1991, the band released a further single, "Talking Back", the Blasting Off album on the tiny Sparkhead label, after which Reed broke up what was left of the band. In 2003, Reed revived the name Red Lorry Yellow Lorry and released four new songs in 2004, available via internet download only on the band’s website; the band toured in the UK during 2004 and 2005, but although journalist Mick Mercer wrote in 2014 that "new material is on its way", no additional Red Lorry Yellow Lorry music has subsequently been released. In 2005, the band released Thunder in the Black Cave, a live DVD recorded in Belgium during their 2004 European tour.
In 2006, Reed released an acoustic-based album, Minimal Animal, under the name'Chris Reed Unit'.

A percussion instrument is a musical instrument, sounded by being struck or scraped by a beater. The percussion family is believed to include the oldest musical instruments, following the human voice; the percussion section of an orchestra most contains instruments such as timpani, snare drum, bass drum, cymbals and tambourine. However, the section can contain non-percussive instruments, such as whistles and sirens, or a blown conch shell. Percussive techniques can be applied to the human body, as in body percussion. On the other hand, keyboard instruments, such as the celesta, are not part of the percussion section, but keyboard percussion instruments such as the glockenspiel and xylophone are included. Percussion instruments are most divided into two classes: Pitched percussion instruments, which produce notes with an identifiable pitch, unpitched percussion instruments, which produce notes or sounds without an identifiable pitch. Percussion instruments may play not only rhythm, but melody and harmony.
Percussion is referred to as "the backbone" or "the heartbeat" of a musical ensemble working in close collaboration with bass instruments, when present. In jazz and other popular music ensembles, the pianist, bassist and sometimes the guitarist are referred to as the rhythm section. Most classical pieces written for full orchestra since the time of Haydn and Mozart are orchestrated to place emphasis on the strings and brass; however at least one pair of timpani is included, though they play continuously. Rather, they serve to provide additional accents. In the 18th and 19th centuries, other percussion instruments have been used, again sparingly; the use of percussion instruments became more frequent in the 20th century classical music. In every style of music, percussion plays a pivotal role. In military marching bands and pipes and drums, it is the beat of the bass drum that keeps the soldiers in step and at a regular speed, it is the snare that provides that crisp, decisive air to the tune of a regiment.
In classic jazz, one immediately thinks of the distinctive rhythm of the hi-hats or the ride cymbal when the word "swing" is spoken. In more recent popular music culture, it is impossible to name three or four rock, hip-hop, funk or soul charts or songs that do not have some sort of percussive beat keeping the tune in time; because of the diversity of percussive instruments, it is not uncommon to find large musical ensembles composed of percussion. Rhythm and harmony are all represented in these ensembles. Music for pitched percussion instruments can be notated on a staff with the same treble and bass clefs used by many non-percussive instruments. Music for percussive instruments without a definite pitch can be notated with a specialist rhythm or percussion-clef. Percussion instruments are classified by various criteria sometimes depending on their construction, ethnic origin, function within musical theory and orchestration, or their relative prevalence in common knowledge; the word "percussion" derives from Latin the terms: "percussio", "percussus".
As a noun in contemporary English, Wiktionary describes it as "the collision of two bodies to produce a sound." The term has application in medicine and weaponry, as in percussion cap. However, all known uses of percussion appear to share a similar lineage beginning with the original Latin: "percussus". In a musical context the percussion instruments may have been coined to describe a family of musical instruments including drums, metal plates, or blocks that musicians beat or struck to produce sound. Hornbostel–Sachs has no high-level section for percussion. Most percussion instruments are classified as membranophones; however the term percussion is instead used at lower-levels of the Hornbostel–Sachs hierarchy, including to identify instruments struck with either a non-sonorous object or against a non-sonorous object. This is opposed to concussion, which refers to instruments with two or more complementary sonorous parts that strike against each other and other meanings. For example: 111.1 Concussion idiophones or clappers, played in pairs and beaten against each other, such as zills and clapsticks.
111.2 Percussion idiophones, includes many percussion instruments played with the hand or by a percussion mallet, such as the hang and the xylophone, but not drums and only some cymbals. 21 Struck drums, includes most types of drum, such as the timpani, snare drum, tom-tom. (Included in most drum sets or 412.12 Percussion reeds, a class of wind instrument unrelated to percussion in the more common sense There are many instruments that have some claim to being percussion, but are classified otherwise: Keyboard instruments such as the celesta and piano. Stringed instruments played with beaters such as the hammered dulcimer. Unpitched whistles and similar instruments, such as the pea whistle and Acme siren. Percussion instruments are sometimes classified as "pitched" or "unpitched". While valid, this classification is seen as inadequate. Rather, it may be more informative to describe percussion instruments in regards to one or more of the following four paradigms: Many texts, including Teaching Percussion by Gary Cook of the University of Arizona, begin by studying the physica
Beatboxing is a form of vocal percussion involving the art of mimicking drum machines, using one's mouth, lips and voice. It may involve vocal imitation of turntablism, other musical instruments. Beatboxing today is connected with hip-hop culture referred to as "the fifth element" of hip-hop, although it is not limited to hip-hop music; the term "beatboxing" is sometimes used to refer to vocal percussion in general. Techniques similar to beatboxing have been present in many American musical genres since the 19th century, such as early rural music, both black and white, religious songs, ragtime and hokum. Examples include the Appalachian technique of eefing and the blues song Bye bye bird by Sonny Boy Williamson II. Additional influences may include forms of African traditional music, in which performers utilize their bodies as percussion instruments and produce sounds with their mouths by breathing loudly in and out, a technique used in beatboxing today. Vocal percussion, "the imitation or approximation of percussion instruments," and beatboxing is a form of vocal percussion but can be described as, "music with your mouth... beatboxing is making and being the music, not just rhythm."...
Beatboxing is both the rhythm — predominantely through the bass and snare drums as well as hi-hat — while incorporating various sound effects such as DJ scratching and bass lines. Using the mouth, lips and voice to make music is thus the beatboxer's equivalent to a pianist's fingers and arms. Many well-known performers used vocal percussion even though this was not directly connected to the cultural tradition that came to be known as beatboxing. Paul McCartney's. Pink Floyd's "Pow R. Toc H." includes vocal percussion performed by the group's lead vocalist, Syd Barrett. Jazz singers Bobby McFerrin and Al Jarreau were well known for their vocal styles and techniques, which have had great impact on techniques beatboxers use today. Michael Jackson was known to record himself beatboxing on a dictation tape recorder as a demo and scratch recording to compose several of his songs, including "Billie Jean", "The Girl Is Mine", others. Gert Fröbe, a German actor most known for playing Auric Goldfinger in the James Bond film Goldfinger, "beatboxes" as Colonel Manfred von Holstein in Those Magnificent Men in their Flying Machines, a 1965 British comedy film.
The term "beatboxing" is derived from the mimicry of early drum machines known as beatboxes the Roland TR-808. The term "beatbox" was used to refer to earlier Roland drum machines such as the TR-55 and CR-78 in the 1970s, they were followed by the TR-808, released in 1980, which became central to hip hop music and electronic dance music. It is the TR-808 that human beatboxing is modeled after."Human beatboxing" in hip-hop originated in the 1980s. Its early pioneers include Doug E. Fresh, the self-proclaimed first "human beatbox". Wise inspired an entire new fan base of human beatboxers with his human turntable technique. Other pioneers of beatboxing include Rahzel well known for his realistic robotic sounds and for his ability to sing and beatbox Scratch a beatboxer and musician well known for further revolutionizing the use of vocal scratching in beatboxing, Kenny Muhammad The Human Orchestra, a beatboxer known for his technicality and outstanding rhythmic precision, who pioneered the inward k snare, a beatbox technique that imitates a snare drum by breathing inward.
The Internet has played a large part in the popularity of modern beatboxing. Alex Tew started the first online community of beatboxers in 2000 under the banner of HUMANBEATBOX. COM. An early example of modern beatboxing was seen in the 2001 South Korean romantic comedy film My Sassy Girl. In 2001, Gavin Tyte, a member of this community created the world's first tutorials and video tutorials on beatboxing. In 2003, the community held the world's first Human Beatbox Convention in London featuring beatbox artists from all over the world. Beatboxing's current popularity is due in part to releases from artists such as Rahzel, RoxorLoops, Reeps One, Alem. Sometimes, modern beatboxers will use their hand or another part of their body to extend the spectrum of sound effects and rhythm; some have developed a technique that involves blowing and sucking air around their fingers to produce a realistic record scratching noise, known as the "crab scratch." Another hand technique includes the "throat tap," which involves beatboxers tapping their fingers against their throats as they throat sing or hum.
Beat boxers these days can produce upto 8 different sounds at the same time. Today there is an increase in the variety. People have gone as far as adding beatboxing in with different instruments to create a different sound unlike any other. Artist Greg Patillo goes as far as adding in beatboxing while playing the flute to iconic songs. Beatbox has become modernized and has been seen in popular movies such as Pitch Perfect and Pitch Perfect 2. Both of these movies showcase classical songs performed with a cappella covers in which all of the beats to the songs are done using the idea and technique of beatboxing to complete the sound capable to imitate the original song; as with other musical disciplines, some form of musical not
An album is a collection of audio recordings issued as a collection on compact disc, audio tape, or another medium. Albums of recorded music were developed in the early 20th century as individual 78-rpm records collected in a bound book resembling a photograph album. Vinyl LPs are still issued, though album sales in the 21st-century have focused on CD and MP3 formats; the audio cassette was a format used alongside vinyl from the 1970s into the first decade of the 2000s. An album may be recorded in a recording studio, in a concert venue, at home, in the field, or a mix of places; the time frame for recording an album varies between a few hours to several years. This process requires several takes with different parts recorded separately, brought or "mixed" together. Recordings that are done in one take without overdubbing are termed "live" when done in a studio. Studios are built to absorb sound, eliminating reverberation, so as to assist in mixing different takes. Recordings, including live, may contain sound effects, voice adjustments, etc..
With modern recording technology, musicians can be recorded in separate rooms or at separate times while listening to the other parts using headphones. Album covers and liner notes are used, sometimes additional information is provided, such as analysis of the recording, lyrics or librettos; the term "album" was applied to a collection of various items housed in a book format. In musical usage the word was used for collections of short pieces of printed music from the early nineteenth century. Collections of related 78rpm records were bundled in book-like albums; when long-playing records were introduced, a collection of pieces on a single record was called an album. An album, in ancient Rome, was a board chalked or painted white, on which decrees and other public notices were inscribed in black, it was from this that in medieval and modern times album came to denote a book of blank pages in which verses, sketches and the like are collected. Which in turn led to the modern meaning of an album as a collection of audio recordings issued as a single item.
In the early nineteenth century "album" was used in the titles of some classical music sets, such as Schumann's Album for the Young Opus 68, a set of 43 short pieces. When 78rpm records came out, the popular 10-inch disc could only hold about three minutes of sound per side, so all popular recordings were limited to around three minutes in length. Classical-music and spoken-word items were released on the longer 12-inch 78s, about 4–5 minutes per side. For example, in 1924, George Gershwin recorded a drastically shortened version of the seventeen-minute Rhapsody in Blue with Paul Whiteman and His Orchestra, it ran for 8m 59s. Deutsche Grammophon had produced an album for its complete recording of the opera Carmen in 1908. German record company Odeon released the Nutcracker Suite by Tchaikovsky in 1909 on 4 double-sided discs in a specially designed package; this practice of issuing albums does not seem to have been taken up by other record companies for many years. By about 1910, bound collections of empty sleeves with a paperboard or leather cover, similar to a photograph album, were sold as record albums that customers could use to store their records.
These albums came in both 12-inch sizes. The covers of these bound books were wider and taller than the records inside, allowing the record album to be placed on a shelf upright, like a book, suspending the fragile records above the shelf and protecting them. In the 1930s, record companies began issuing collections of 78 rpm records by one performer or of one type of music in specially assembled albums with artwork on the front cover and liner notes on the back or inside cover. Most albums included three or four records, with two sides each, making six or eight compositions per album; the 12-inch LP record, or 33 1⁄3 rpm microgroove vinyl record, is a gramophone record format introduced by Columbia Records in 1948. A single LP record had the same or similar number of tunes as a typical album of 78s, it was adopted by the record industry as a standard format for the "album". Apart from minor refinements and the important addition of stereophonic sound capability, it has remained the standard format for vinyl albums.
The term "album" was extended to other recording media such as Compact audio cassette, compact disc, MiniDisc, digital albums, as they were introduced. As part of a trend of shifting sales in the music industry, some observers feel that the early 21st century experienced the death of the album. While an album may contain as many or as few tracks as required, in the United States, The Recording Academy's rules for Grammy Awards state that an album must comprise a minimum total playing time of 15 minutes with at least five distinct tracks or a minimum total playing time of 30 minutes with no minimum track requirement. In the United Kingdom, the criteria for the UK Albums Chart is that a recording counts as an "album" i
Rock and roll
Rock and roll is a genre of popular music that originated and evolved in the United States during the late 1940s and early 1950s from musical styles such as gospel, jump blues, boogie woogie, rhythm and blues, along with country music. While elements of what was to become rock and roll can be heard in blues records from the 1920s and in country records of the 1930s, the genre did not acquire its name until 1954. According to Greg Kot, "rock and roll" refers to a style of popular music originating in the U. S. in the 1950s prior to its development by the mid-1960s into "the more encompassing international style known as rock music, though the latter continued to be known as rock and roll." For the purpose of differentiation, this article deals with the first definition. In the earliest rock and roll styles, either the piano or saxophone was the lead instrument, but these instruments were replaced or supplemented by guitar in the middle to late 1950s; the beat is a dance rhythm with an accentuated backbeat, always provided by a snare drum.
Classic rock and roll is played with one or two electric guitars, a double bass or string bass or an electric bass guitar, a drum kit. Beyond a musical style and roll, as seen in movies, in fan magazines, on television, influenced lifestyles, fashion and language. In addition and roll may have contributed to the civil rights movement because both African-American and white American teenagers enjoyed the music, it went on to spawn various genres without the characteristic backbeat, that are now more called "rock music" or "rock". The term "rock and roll" now has at least two different meanings, both in common usage; the American Heritage Dictionary and the Merriam-Webster Dictionary both define rock and roll as synonymous with rock music. Encyclopædia Britannica, on the other hand, regards it as the music that originated in the mid-1950s and developed "into the more encompassing international style known as rock music"; the phrase "rocking and rolling" described the movement of a ship on the ocean, but was used by the early twentieth century, both to describe the spiritual fervor of black church rituals and as a sexual analogy.
Various gospel and swing recordings used the phrase before it became used more – but still intermittently – in the 1940s, on recordings and in reviews of what became known as "rhythm and blues" music aimed at a black audience. In 1934, the song "Rock and Roll" by the Boswell Sisters appeared in the film Transatlantic Merry-Go-Round. In 1942, Billboard magazine columnist Maurie Orodenker started to use the term "rock-and-roll" to describe upbeat recordings such as "Rock Me" by Sister Rosetta Tharpe. By 1943, the "Rock and Roll Inn" in South Merchantville, New Jersey, was established as a music venue. In 1951, Ohio, disc jockey Alan Freed began playing this music style while popularizing the phrase to describe it; the origins of rock and roll have been fiercely debated by historians of music. There is general agreement that it arose in the Southern United States – a region that would produce most of the major early rock and roll acts – through the meeting of various influences that embodied a merging of the African musical tradition with European instrumentation.
The migration of many former slaves and their descendants to major urban centers such as St. Louis, New York City, Chicago and Buffalo meant that black and white residents were living in close proximity in larger numbers than before, as a result heard each other's music and began to emulate each other's fashions. Radio stations that made white and black forms of music available to both groups, the development and spread of the gramophone record, African-American musical styles such as jazz and swing which were taken up by white musicians, aided this process of "cultural collision"; the immediate roots of rock and roll lay in the rhythm and blues called "race music", country music of the 1940s and 1950s. Significant influences were jazz, gospel and folk. Commentators differ in their views of which of these forms were most important and the degree to which the new music was a re-branding of African-American rhythm and blues for a white market, or a new hybrid of black and white forms. In the 1930s, swing, both in urban-based dance bands and blues-influenced country swing, were among the first music to present African-American sounds for a predominantly white audience.
One noteworthy example of a jazz song with recognizably rock and roll elements is Big Joe Turner with pianist Pete Johnson's 1939 single Roll'Em Pete, regarded as an important precursor of rock and roll. The 1940s saw the increased use of blaring horns, shouted lyrics and boogie woogie beats in jazz-based music. During and after World War II, with shortages of fuel and limitations on audiences and available personnel, large jazz bands were less economical and tended to be replaced by smaller combos, using guitars and drums. In the same period on the West Coast and in the Midwest, the development of jump blues, with its guitar riffs, prominent beats and shouted lyrics, prefigured many developments. In the documentary film Hail! Hail! Rock'n' Roll, Keith Richards proposes that Chuck Berry developed his brand of rock and roll by transposing the familiar two-note lead line of jump blues piano directly to the electric guitar, creatin
