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.

Los Angeles the City of Los Angeles and known by its initials L. A. is the most populous city in California, the second most populous city in the United States, after New York City, the third most populous city in North America. With an estimated population of four million, Los Angeles is the cultural and commercial center of Southern California; the city is known for its Mediterranean climate, ethnic diversity and the entertainment industry, its sprawling metropolis. Los Angeles is the largest city on the West Coast of North America. Los Angeles is in a large basin bounded by the Pacific Ocean on one side and by mountains as high as 10,000 feet on the other; the city proper, which covers about 469 square miles, is the seat of Los Angeles County, the most populated county in the country. Los Angeles is the principal city of the Los Angeles metropolitan area, the second largest in the United States after that of New York City, with a population of 13.1 million. It is part of the Los Angeles-Long Beach combined statistical area the nation's second most populous area with a 2015 estimated population of 18.7 million.
Los Angeles is one of the most substantial economic engines within the United States, with a diverse economy in a broad range of professional and cultural fields. Los Angeles is famous as the home of Hollywood, a major center of the world entertainment industry. A global city, it has been ranked 6th in the Global Cities Index and 9th in the Global Economic Power Index; the Los Angeles metropolitan area has a gross metropolitan product of $1.044 trillion, making it the third-largest in the world, after the Tokyo and New York metropolitan areas. Los Angeles hosted the 1932 and 1984 Summer Olympics and will host the event for a third time in 2028; the city hosted the Miss Universe pageant twice, in 1990 and 2006, was one of 9 American cities to host the 1994 FIFA men's soccer World Cup and one of 8 to host the 1999 FIFA women's soccer World Cup, hosting the final match for both tournaments. Home to the Chumash and Tongva, Los Angeles was claimed by Juan Rodríguez Cabrillo for Spain in 1542 along with the rest of what would become Alta California.
The city was founded on September 4, 1781, by Spanish governor Felipe de Neve. It became a part of Mexico in 1821 following the Mexican War of Independence. In 1848, at the end of the Mexican–American War, Los Angeles and the rest of California were purchased as part of the Treaty of Guadalupe Hidalgo, becoming part of the United States. Los Angeles was incorporated as a municipality on April 4, 1850, five months before California achieved statehood; the discovery of oil in the 1890s brought rapid growth to the city. The completion of the Los Angeles Aqueduct in 1913, delivering water from Eastern California assured the city's continued rapid growth; the Los Angeles coastal area was settled by the Chumash tribes. A Gabrieleño settlement in the area was called iyáangẚ, meaning "poison oak place". Maritime explorer Juan Rodríguez Cabrillo claimed the area of southern California for the Spanish Empire in 1542 while on an official military exploring expedition moving north along the Pacific coast from earlier colonizing bases of New Spain in Central and South America.
Gaspar de Portolà and Franciscan missionary Juan Crespí, reached the present site of Los Angeles on August 2, 1769. In 1771, Franciscan friar Junípero Serra directed the building of the Mission San Gabriel Arcángel, the first mission in the area. On September 4, 1781, a group of forty-four settlers known as "Los Pobladores" founded the pueblo they called El Pueblo de Nuestra Señora la Reina de los Ángeles,'The Town of Our Lady the Queen of the Angels'; the present-day city has the largest Roman Catholic Archdiocese in the United States. Two-thirds of the Mexican or settlers were mestizo or mulatto, a mixture of African and European ancestry; the settlement remained a small ranch town for decades, but by 1820, the population had increased to about 650 residents. Today, the pueblo is commemorated in the historic district of Los Angeles Pueblo Plaza and Olvera Street, the oldest part of Los Angeles. New Spain achieved its independence from the Spanish Empire in 1821, the pueblo continued as a part of Mexico.
During Mexican rule, Governor Pío Pico made Los Angeles Alta California's regional capital. Mexican rule ended during the Mexican–American War: Americans took control from the Californios after a series of battles, culminating with the signing of the Treaty of Cahuenga on January 13, 1847. Railroads arrived with the completion of the transcontinental Southern Pacific line to Los Angeles in 1876 and the Santa Fe Railroad in 1885. Petroleum was discovered in the city and surrounding area in 1892, by 1923, the discoveries had helped California become the country's largest oil producer, accounting for about one-quarter of the world's petroleum output. By 1900, the population had grown to more than 102,000; the completion of the Los Angeles Aqueduct in 1913, under the supervision of William Mulholland, assured the continued growth of the city. Due to clauses in the city's charter that prevented the City of Los Angeles from selling or providing water from the aqueduct to any area outside its borders, many adjacent city and communities became compelled to annex themselves into Los Angeles.
Los Angeles created the first municipal zoning ordinance in the United States. On September 14, 1908, the Los Angeles City Council promulgated residential and industrial land use zones; the new ordinance established three residential zones of a single type, where industrial uses were
Pop music is a genre of popular music that originated in its modern form in the United States and United Kingdom during the mid-1950s. The terms "popular music" and "pop music" are used interchangeably, although the former describes all music, popular and includes many diverse styles. "Pop" and "rock" were synonymous terms until the late 1960s, when they became differentiated from each other. Although much of the music that appears on record charts is seen as pop music, the genre is distinguished from chart music. Pop music is eclectic, borrows elements from other styles such as urban, rock and country. Identifying factors include short to medium-length songs written in a basic format, as well as common use of repeated choruses, melodic tunes, hooks. David Hatch and Stephen Millward define pop music as "a body of music, distinguishable from popular and folk musics". According to Pete Seeger, pop music is "professional music which draws upon both folk music and fine arts music". Although pop music is seen as just the singles charts, it is not the sum of all chart music.
The music charts contain songs from a variety of sources, including classical, jazz and novelty songs. As a genre, pop music is seen to develop separately. Therefore, the term "pop music" may be used to describe a distinct genre, designed to appeal to all characterized as "instant singles-based music aimed at teenagers" in contrast to rock music as "album-based music for adults". Pop music continuously evolves along with the term's definition. According to music writer Bill Lamb, popular music is defined as "the music since industrialization in the 1800s, most in line with the tastes and interests of the urban middle class." The term "pop song" was first used in 1926, in the sense of a piece of music "having popular appeal". Hatch and Millward indicate that many events in the history of recording in the 1920s can be seen as the birth of the modern pop music industry, including in country and hillbilly music. According to the website of The New Grove Dictionary of Music and Musicians, the term "pop music" "originated in Britain in the mid-1950s as a description for rock and roll and the new youth music styles that it influenced".
The Oxford Dictionary of Music states that while pop's "earlier meaning meant concerts appealing to a wide audience since the late 1950s, pop has had the special meaning of non-classical mus in the form of songs, performed by such artists as the Beatles, the Rolling Stones, ABBA, etc." Grove Music Online states that " in the early 1960s,'pop music' competed terminologically with beat music, while in the US its coverage overlapped with that of'rock and roll'". From about 1967, the term “pop music” was used in opposition to the term rock music, a division that gave generic significance to both terms. While rock aspired to authenticity and an expansion of the possibilities of popular music, pop was more commercial and accessible. According to British musicologist Simon Frith, pop music is produced "as a matter of enterprise not art", is "designed to appeal to everyone" but "doesn't come from any particular place or mark off any particular taste". Frith adds that it is "not driven by any significant ambition except profit and commercial reward and, in musical terms, it is conservative".
It is, "provided from on high rather than being made from below... Pop is not a do-it-yourself music but is professionally produced and packaged". According to Frith, characteristics of pop music include an aim of appealing to a general audience, rather than to a particular sub-culture or ideology, an emphasis on craftsmanship rather than formal "artistic" qualities. Music scholar Timothy Warner said it has an emphasis on recording and technology, rather than live performance; the main medium of pop music is the song between two and a half and three and a half minutes in length marked by a consistent and noticeable rhythmic element, a mainstream style and a simple traditional structure. Common variants include the verse-chorus form and the thirty-two-bar form, with a focus on melodies and catchy hooks, a chorus that contrasts melodically and harmonically with the verse; the beat and the melodies tend to be simple, with limited harmonic accompaniment. The lyrics of modern pop songs focus on simple themes – love and romantic relationships – although there are notable exceptions.
Harmony and chord progressions in pop music are "that of classical European tonality, only more simple-minded." Clichés include the barbershop quartet-style blues scale-influenced harmony. There was a lessening of the influence of traditional views of the circle of fifths between the mid-1950s and the late 1970s, including less predominance for the dominant function. Throughout its development, pop music has absorbed influences from other genres of popular music. Early pop music drew on the sentimental ballad for its form, gained its use of vocal harmonies from gospel and soul music, instrumentation from jazz and rock music, orchestration from classical music, tempo from dance music, backing from electronic music, rhythmic elements from hip-hop music, spoken passages from rap. In the 1960s, the majority of mainstream pop music fell in two categories: guitar and bass groups or singers
The United States of America known as the United States or America, is a country composed of 50 states, a federal district, five major self-governing territories, various possessions. At 3.8 million square miles, the United States is the world's third or fourth largest country by total area and is smaller than the entire continent of Europe's 3.9 million square miles. With a population of over 327 million people, the U. S. is the third most populous country. The capital is Washington, D. C. and the largest city by population is New York City. Forty-eight states and the capital's federal district are contiguous in North America between Canada and Mexico; the State of Alaska is in the northwest corner of North America, bordered by Canada to the east and across the Bering Strait from Russia to the west. The State of Hawaii is an archipelago in the mid-Pacific Ocean; the U. S. territories are scattered about the Pacific Ocean and the Caribbean Sea, stretching across nine official time zones. The diverse geography and wildlife of the United States make it one of the world's 17 megadiverse countries.
Paleo-Indians migrated from Siberia to the North American mainland at least 12,000 years ago. European colonization began in the 16th century; the United States emerged from the thirteen British colonies established along the East Coast. Numerous disputes between Great Britain and the colonies following the French and Indian War led to the American Revolution, which began in 1775, the subsequent Declaration of Independence in 1776; the war ended in 1783 with the United States becoming the first country to gain independence from a European power. The current constitution was adopted in 1788, with the first ten amendments, collectively named the Bill of Rights, being ratified in 1791 to guarantee many fundamental civil liberties; the United States embarked on a vigorous expansion across North America throughout the 19th century, acquiring new territories, displacing Native American tribes, admitting new states until it spanned the continent by 1848. During the second half of the 19th century, the Civil War led to the abolition of slavery.
By the end of the century, the United States had extended into the Pacific Ocean, its economy, driven in large part by the Industrial Revolution, began to soar. The Spanish–American War and World War I confirmed the country's status as a global military power; the United States emerged from World War II as a global superpower, the first country to develop nuclear weapons, the only country to use them in warfare, a permanent member of the United Nations Security Council. Sweeping civil rights legislation, notably the Civil Rights Act of 1964, the Voting Rights Act of 1965 and the Fair Housing Act of 1968, outlawed discrimination based on race or color. During the Cold War, the United States and the Soviet Union competed in the Space Race, culminating with the 1969 U. S. Moon landing; the end of the Cold War and the collapse of the Soviet Union in 1991 left the United States as the world's sole superpower. The United States is the world's oldest surviving federation, it is a representative democracy.
The United States is a founding member of the United Nations, World Bank, International Monetary Fund, Organization of American States, other international organizations. The United States is a developed country, with the world's largest economy by nominal GDP and second-largest economy by PPP, accounting for a quarter of global GDP; the U. S. economy is post-industrial, characterized by the dominance of services and knowledge-based activities, although the manufacturing sector remains the second-largest in the world. The United States is the world's largest importer and the second largest exporter of goods, by value. Although its population is only 4.3% of the world total, the U. S. holds 31% of the total wealth in the world, the largest share of global wealth concentrated in a single country. Despite wide income and wealth disparities, the United States continues to rank high in measures of socioeconomic performance, including average wage, human development, per capita GDP, worker productivity.
The United States is the foremost military power in the world, making up a third of global military spending, is a leading political and scientific force internationally. In 1507, the German cartographer Martin Waldseemüller produced a world map on which he named the lands of the Western Hemisphere America in honor of the Italian explorer and cartographer Amerigo Vespucci; the first documentary evidence of the phrase "United States of America" is from a letter dated January 2, 1776, written by Stephen Moylan, Esq. to George Washington's aide-de-camp and Muster-Master General of the Continental Army, Lt. Col. Joseph Reed. Moylan expressed his wish to go "with full and ample powers from the United States of America to Spain" to seek assistance in the revolutionary war effort; the first known publication of the phrase "United States of America" was in an anonymous essay in The Virginia Gazette newspaper in Williamsburg, Virginia, on April 6, 1776. The second draft of the Articles of Confederation, prepared by John Dickinson and completed by June 17, 1776, at the latest, declared "The name of this Confederation shall be the'United States of America'".
The final version of the Articles sent to the states for ratification in late 1777 contains the sentence "The Stile of this Confederacy shall be'The United States of America'". In June 1776, Thomas Jefferson wrote the phrase "UNITED STATES OF AMERICA" in all capitalized letters in the headline of his "original Rough draught" of the Declaration of Independence; this draft of the document did not surface unti
A music video is a short film that integrates a song with imagery, is produced for promotional or artistic purposes. Modern music videos are made and used as a marketing device intended to promote the sale of music recordings. There are cases where songs are used in tie-in marketing campaigns that allow them to become more than just a song. Tie-ins and merchandising can be used for food or other products. Although the origins of the music video date back to musical short films that first appeared in the 1920s, they again came into prominence in the 1980s when the channel MTV based their format around the medium. Prior to the 1980s, these kinds of videos were described by various terms including "illustrated song", "filmed insert", "promotional film", "promotional clip", "promotional video", "song video", "song clip" or "film clip". Music videos use a wide range of styles and contemporary video-making techniques, including animation, live action and non-narrative approaches such as abstract film.
Some music videos combine different styles with the music, such as animation and live action. Combining these styles and techniques has become more popular because of the variety for the audience. Many music videos interpret images and scenes from the song's lyrics, while others take a more thematic approach. Other music videos may not have any concept, being a filmed version of the song's live concert performance. In 1894, sheet music publishers Edward B. Marks Joe Stern hired electrician George Thomas and various performers to promote sales of their song "The Little Lost Child". Using a magic lantern, Thomas projected a series of still images on a screen simultaneous to live performances; this would become a popular form of entertainment known as the illustrated song, the first step toward music video. In 1926, with the arrival of "talkies" many musical short films were produced. Vitaphone shorts featured many bands and dancers. Animation artist Max Fleischer introduced a series of sing-along short cartoons called Screen Songs, which invited audiences to sing along to popular songs by "following the bouncing ball", similar to a modern karaoke machine.
Early 1930s cartoons featured popular musicians performing their hit songs on-camera in live-action segments during the cartoons. The early animated films by Walt Disney, such as the Silly Symphonies shorts and Fantasia, which featured several interpretations of classical pieces, were built around music; the Warner Bros. cartoons today billed as Looney Tunes and Merrie Melodies, were fashioned around specific songs from upcoming Warner Bros. musical films. Live action musical shorts, featuring such popular performers as Cab Calloway, were distributed to theaters. Blues singer Bessie Smith appeared in a two-reel short film called St. Louis Blues featuring a dramatized performance of the hit song. Numerous other musicians appeared in short musical subjects during this period. Soundies and released from 1940 to 1947, were musical films that included short dance sequences, similar to music videos. In the mid-1940s, musician Louis Jordan made short films for his songs, some of which were spliced together into a feature film, Lookout Sister.
These films were, according to music historian Donald Clarke, the "ancestors" of music video. Musical films were another important precursor to music video, several well-known music videos have imitated the style of classic Hollywood musicals from the 1930s to the 1950s. One of the best-known examples is Madonna's 1985 video for "Material Girl", modelled on Jack Cole's staging of "Diamonds Are A Girl's Best Friend" from the film Gentlemen Prefer Blondes. Several of Michael Jackson's videos show the unmistakable influence of the dance sequences in classic Hollywood musicals, including the landmark "Thriller" and the Martin Scorsese-directed "Bad", influenced by the stylised dance "fights" in the film version of West Side Story. According to the Internet Accuracy Project, disc jockey–singer J. P. "The Big Bopper" Richardson was the first to coin the phrase "music video", in 1959. In his autobiography, Tony Bennett claims to have created "...the first music video" when he was filmed walking along the Serpentine in Hyde Park, London in 1956, with the resulting clip being set to his recording of the song "Stranger in Paradise".
The clip was sent to UK and US television stations and aired on shows including Dick Clark's American Bandstand. The oldest example of a promotional music video with similarities to more abstract, modern videos seems to be the Czech "Dáme si do bytu" created in 1958 and directed by Ladislav Rychman. In the late 1950s the Scopitone, a visual jukebox, was invented in France and short films were produced by many French artists, such as Serge Gainsbourg, Françoise Hardy, Jacques Dutronc, the Belgian Jacques Brel to accompany their songs, its use spread to other countries, similar machines such as the Cinebox in Italy and Color-Sonic in the USA were patented. In 1961, for the Canadian show Singalong Jubilee, Manny Pittson began pre-recording the music audio, went on-location and taped various visuals with the musicians lip-synching edited the audio and video together. Most music numbers were taped in-studio on stage, the location shoot "videos" were to add variety. In 1964, Kenneth Anger's experimental short film, Scorpio Rising used popular songs instead of dialog.
In 1964, The Moody Blues producer, Alex Murray, wanted to promote his version of "Go Now". The short film clip he produced and directed to promote the single has a striking visual style that predates Queen's similar "Bohemian Rhapsody" vid
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
