A song is a single work of music, intended to be sung by the human voice with distinct and fixed pitches and patterns using sound and silence and a variety of forms that include the repetition of sections. Through semantic widening, a broader sense of the word "song" may refer to instrumentals. Written words created for music or for which music is created, are called lyrics. If a pre-existing poem is set to composed music in classical music it is an art song. Songs that are sung on repeated pitches without distinct contours and patterns that rise and fall are called chants. Songs in a simple style that are learned informally are referred to as folk songs. Songs that are composed for professional singers who sell their recordings or live shows to the mass market are called popular songs; these songs, which have broad appeal, are composed by professional songwriters and lyricists. Art songs are composed by trained classical composers for recital performances. Songs are recorded on audio or video.
Songs may appear in plays, musical theatre, stage shows of any form, within operas. A song may be for a solo singer, a lead singer supported by background singers, a duet, trio, or larger ensemble involving more voices singing in harmony, although the term is not used for large classical music vocal forms including opera and oratorio, which use terms such as aria and recitative instead. Songs with more than one voice to a part singing in polyphony or harmony are considered choral works. Songs can be broadly divided depending on the criteria used. Art songs are songs created for performance by classical artists with piano or violin/viola accompaniment, although they can be sung solo. Art songs require strong vocal technique, understanding of language and poetry for interpretation. Though such singers may perform popular or folk songs on their programs, these characteristics and the use of poetry are what distinguish art songs from popular songs. Art songs are a tradition from most European countries, now other countries with classical music traditions.
German-speaking communities use the term art song to distinguish so-called "serious" compositions from folk song. The lyrics are written by a poet or lyricist and the music separately by a composer. Art songs may be more formally complicated than popular or folk songs, though many early Lieder by the likes of Franz Schubert are in simple strophic form; the accompaniment of European art songs is considered as an important part of the composition. Some art songs are so revered. Art songs emerge from the tradition of singing romantic love songs to an ideal or imaginary person and from religious songs; the troubadours and bards of Europe began the documented tradition of romantic songs, continued by the Elizabethan lutenists. Some of the earliest art songs are found in the music of Henry Purcell; the tradition of the romance, a love song with a flowing accompaniment in triple meter, entered opera in the 19th century, spread from there throughout Europe. It became one of the underpinnings of popular songs.
While a romance has a simple accompaniment, art songs tend to have complicated, sophisticated accompaniments that underpin, illustrate or provide contrast to the voice. Sometimes the accompaniment performer has the melody. Folk songs are songs of anonymous origin that are transmitted orally, they are a major aspect of national or cultural identity. Art songs approach the status of folk songs when people forget who the author was. Folk songs are frequently transmitted non-orally in the modern era. Folk songs exist in every culture. Popular songs may become folk songs by the same process of detachment from its source. Folk songs are more-or-less in the public domain by definition, though there are many folk song entertainers who publish and record copyrighted original material; this tradition led to the singer-songwriter style of performing, where an artist has written confessional poetry or personal statements and sings them set to music, most with guitar accompaniment. There are many genres of popular songs, including torch songs, novelty songs, rock and soul songs, other commercial genres, such as rapping.
Folk songs include ballads, plaints, love songs, mourning songs, dance songs, work songs, ritual songs and many more.

Lucent Technologies, Inc. was an American multinational telecommunications equipment company headquartered in Murray Hill, New Jersey, in the United States. It was established on September 30, 1996, through the divestiture of the former AT&T Technologies business unit of AT&T Corporation, which included Western Electric and Bell Labs. Lucent was merged with Alcatel SA of France in a merger of equals on December 1, 2006, forming Alcatel-Lucent. Alcatel-Lucent was absorbed by Nokia in January 2016. Lucent means "they shine" in Latin; the name was applied in 1996 at the time of the split from AT&T. The name was criticised, as the logo was to be, both internally and externally. Corporate communications and business cards included the strapline'Bell Labs Innovations' in a bid to retain the prestige of the internationally famous research lab, within a new business under an as-yet unknown name; this same linguistic root gives Lucifer, "the light bearer", a character in Dante's epic poem Inferno. Shortly after the Lucent renaming in 1996, Lucent's Plan 9 project released a development of their work as the Inferno OS in 1997.
This extended the'Lucifer' and Dante references as a series of punning names for the components of Inferno - Dis, Limbo and Styx. When the rights to Inferno were sold in 2000, the company Vita Nuova Holdings was formed to represent them; this continues the Dante theme, although moving away from his Divine Comedy to the poem La Vita Nuova. The Lucent logo, the Innovation Ring, was designed by Landor Associates, a prominent San Francisco-based branding consultancy. One source inside Lucent says that the logo is a Zen Buddhist symbol for "eternal truth", the Enso, turned 90 degrees and modified. Another source says it represents a snake holding its tail in its mouth. Lucent's logo has been said to represent constant re-creating and re-thinking. Carly Fiorina picked the logo because her mother was a painter and she rejected the sterile geometric logos of most high tech companies. After the logo was compared in the media to the ring a coffee mug leaves on paper, a Dilbert comic strip showed Dogbert as an overpaid consultant designing a new company logo.
A telecommunication commentator referred to the logo as "a big red zero" and predicted financial losses. One of the primary reasons AT&T Corporation chose to spin off its equipment manufacturing business was to permit it to profit from sales to competing telecommunications providers. Bell Labs brought prestige to the new company, as well as the revenue from thousands of patents. At the time of its spinoff, Lucent was placed under the leadership of Henry Schacht, brought in to oversee its transition from an arm of AT&T into an independent corporation. Richard McGinn, serving as President and COO, succeeded Schacht as CEO in 1997 while Schacht remained chairman of the board. Lucent became a "darling" stock of the investment community in the late 1990s, its split-adjusted spinoff price of $7.56/share rose to a high of $84. Its market capitalization reached a high of $258 billion, it was at the time the most held company with 5.3 million shareholders. In 1997, Lucent acquired Milpitas-based voicemail market leader Octel Communications Corporation for $2.1 billion, a move which rendered the Business Systems Group profitable.
By 1999 Lucent stock continued to soar and in that year Lucent acquired Ascend Communications, an Alameda, California–based manufacturer of communications equipment for US$24 billion. Lucent decided instead to build its own routers. In 1997, Lucent acquired Livingston Enterprises Inc. for $650 million in stock. Livingston was known most for the creation of the RADIUS protocol and their PortMaster product, used by dial-up internet service providers. In 1995, Carly Fiorina led corporate operations. In that capacity, she reported to Lucent chief executive Henry B. Schacht, she played a key role in planning and implementing the 1996 initial public offering of a successful stock and company launch strategy. Under her guidance, the spin-off raised US$3 billion. In 1996, Fiorina was appointed president of Lucent's consumer products sector, reporting to president and chief operating officer Rich McGinn. In 1997, she was named group president for Lucent's US$19 billion global service-provider business, overseeing marketing and sales for the company's largest customer segment.
That year, Fiorina chaired a US$2.5 billion joint venture between Lucent's consumer communications and Royal Philips Electronics, under the name Philips Consumer Communications. The focus of the venture was to bring both companies to the top three in technology and brand recognition; the project struggled and dissolved a year after it garnered only 2% market share in mobile phones. Losses were at $500 million on sales of $2.5 billion. As a result of the failed joint venture, Philips announced the closure of one-quarter of the company's 230 factories worldwide, Lucent closed down its wireless handset portion of the venture. Analysts suggested that the joint venture's failure was due to a combination of technology and management problems. Upon the end of the joint venture, PCC sent 5,000 employees back to Philips, many of which were laid off, 8,400 employees back to Lucent. Under Fiorina, the company added 22,000 jobs and revenues seemed to grow from US$19 billion to US$38 billion. However, the real cause of Lucent spurring sales under Fiorina was by lending money to their own customers.
Universal Music Group
Universal Music Group is an American global music corporation, a subsidiary of the French media conglomerate Vivendi. UMG's global corporate headquarters are located in California, it is considered one of the "Big Three" record labels, along with Warner Music Group. Since 2004, the corporation is no longer related to the film studio Universal Studios. Universal Music was once the record company attached to film studio Universal Pictures; the company's origins go back to the formation of the American branch of Decca Records in September 1934. The Decca Record Co. Ltd. of England spun American Decca off in 1939. MCA Inc. merged with American Decca in 1962. In November 1990, Japanese multinational conglomerate Matsushita Electric agreed to acquire MCA for $6.59 billion. In 1995, Seagram acquired 80 percent of MCA from Matsushita. On December 9, 1996, the company was renamed Universal Studios, Inc. and its music division was renamed Universal Music Group. In May 1998, Seagram purchased PolyGram and merged it with Universal Music Group in early 1999.
With the 2004 acquisition of Universal Studios by General Electric and merging with GE's NBC, Universal Music Group was cast under separate management from the eponymous film studio. This is the second time a music company has done so, the first being the separation of Time Warner and Warner Music Group. In February 2006, the label became 100 percent owned by French media conglomerate Vivendi when Vivendi purchased the last 20 percent from Matsushita. On June 25, 2007, Vivendi completed its €1.63 billion purchase of BMG Music Publishing, after receiving European Union regulatory approval, having announced the acquisition on September 6, 2006. Doug Morris stepped down from his position as CEO on January 1, 2011. Former chairman/CEO of Universal Music International Lucian Grainge was promoted to CEO of the company. Grainge replaced him as chairman on March 9, 2011. Morris became the next chairman of Sony Music Entertainment on July 1, 2011. With Grainge's appointment as CEO at UMG, Max Hole was promoted to COO of UMGI, effective July 1, 2010.
Starting in 2011 UMG's Interscope Geffen A&M Records will be signing contestants from American Idol/Idol series. On January 2011, UMG announced it was donating 200,000 master recordings from the 1920s to 1940s to the Library of Congress for preservation. In March 2011, Barry Weiss became chairman and CEO of The Island Def Jam Music Group and Universal Republic Records. Both companies were restructured under Weiss. In December 2011, David Foster was named Chairman of Verve Music Group. In 2011, EMI sold its recorded music operations to Universal Music Group for £1.2 billion and its music publishing operations to a Sony-led consortium for $2.2 billion. Among the other companies that had competed for the recorded music business was Warner Music Group, reported to have made a $2 billion bid. IMPALA opposed the merger. In March 2012, the European Union opened an investigation into the acquisition The EU asked rivals and consumer groups whether the deal would result in higher prices and shut out competitors.
On September 21, 2012, the sale of EMI to UMG was approved in Europe and the United States by the European Commission and Federal Trade Commission respectively. However, the European Commission approved the deal only under the condition the merged company divest one third of its total operations to other companies with a proven track record in the music industry. UMG divested Mute Records, Roxy Recordings, MPS Records, Cooperative Music, Now That's What I Call Music!, Universal Greece, Sanctuary Records, Chrysalis Records, EMI Classics, Virgin Classics, EMI's European regional labels to comply with this condition. UMG retained The Beatles and Robbie Williams; the Beatles catalogue was transferred to UMG's newly formed Calderstone Productions, while Williams' catalogue was transferred to Island Records. Universal Music Group completed their acquisition of EMI on September 28, 2012. In November 2012, Steve Barnett was appointed CEO of Capitol Music Group, he served as COO of Columbia Records. In compliance the conditions of the European Commission after purchase of EMI, Universal Music Group sold the Mute catalogue to the German-based BMG Rights Management on December 22, 2012.
Two months BMG acquired Sanctuary Records for €50 million. On November 8, 2012, Universal Music and Hewlett-Packard launched a marketing operation that allows customers with an HP computer with HP Connected Music software to access music from Universal artists, as well as exclusive content. On February 8, 2013, Warner Music Group acquired the Parlophone Label Group for $765 million. In February, Sony Music Entertainment acquired Universal's European share in Now That's What I Call Music for $60 million. Play It Again Sam acquired Co-Operative Music for £500,000 in March 2013. With EMI's absorption into Universal Music complete, its British operations will consist of five label units: Island, Decca, Virgin EMI and Capitol. In April 2013, Universal Music Greece was sold to Victoras Antippas, who renamed the company Cobalt Music. Edel AG acquired the MPS catalogue from Universal in January 2014. On March 20, 2013, UMG announced the worldwide extension of their exclusive distribution deal with the Disney Music Group, excluding Japan and Russia.
As a result of t
September 11 attacks
The September 11 attacks were a series of four coordinated terrorist attacks by the Islamic terrorist group al-Qaeda against the United States on the morning of Tuesday, September 11, 2001. The attacks killed 2,996 people, injured over 6,000 others, caused at least $10 billion in infrastructure and property damage. Additional people died of 9/11-related cancer and respiratory diseases in the months and years following the attacks. Four passenger airliners operated by two major U. S. passenger air carriers —all of which departed from airports in the northeastern United States bound for California—were hijacked by 19 al-Qaeda terrorists. Two of the planes, American Airlines Flight 11 and United Airlines Flight 175, were crashed into the North and South towers of the World Trade Center complex in Lower Manhattan. Within an hour and 42 minutes, both 110-story towers collapsed. Debris and the resulting fires caused a partial or complete collapse of all other buildings in the World Trade Center complex, including the 47-story 7 World Trade Center tower, as well as significant damage to ten other large surrounding structures.
A third plane, American Airlines Flight 77, was crashed into the Pentagon in Arlington County, which led to a partial collapse of the building's west side. The fourth plane, United Airlines Flight 93, was flown toward Washington, D. C. but crashed into a field in Stonycreek Township near Shanksville, after its passengers thwarted the hijackers. 9/11 is the single deadliest terrorist attack in human history and the single deadliest incident for firefighters and law enforcement officers in the history of the United States, with 343 and 72 killed, respectively. Suspicion fell on al-Qaeda; the United States responded by launching the War on Terror and invaded Afghanistan to depose the Taliban, which had failed to comply with U. S. demands to extradite Osama bin expel al-Qaeda from Afghanistan. Many countries strengthened their anti-terrorism legislation and expanded the powers of law enforcement and intelligence agencies to prevent terrorist attacks. Although Osama bin Laden, al-Qaeda's leader denied any involvement, in 2004 he claimed responsibility for the attacks.
Al-Qaeda and bin Laden cited U. S. support of Israel, the presence of U. S. troops in Saudi Arabia, sanctions against Iraq as motives. After evading capture for a decade, bin Laden was located in Pakistan and killed by SEAL Team Six of the U. S. Navy in May 2011; the destruction of the World Trade Center and nearby infrastructure harmed the economy of Lower Manhattan and had a significant effect on global markets, which resulted in the closing of Wall Street until September 17 and the civilian airspace in the U. S. and Canada until September 13. Many closings and cancellations followed, out of respect or fear of further attacks. Cleanup of the World Trade Center site was completed in May 2002, the Pentagon was repaired within a year. On November 18, 2006, construction of One World Trade Center began at the World Trade Center site; the building was opened on November 3, 2014. Numerous memorials have been constructed, including the National September 11 Memorial & Museum in New York City, the Pentagon Memorial in Arlington County and the Flight 93 National Memorial in a field in Stonycreek Township near Shanksville, Pennsylvania.
Although not confirmed, there is evidence of alleged Saudi Arabian involvement in the attacks. Given as main evidence in these charges are the contents of the 28 redacted pages of the December 2002 Joint Inquiry into Intelligence Community Activities before and after the Terrorist Attacks of September 11, 2001 conducted by the Senate Select Committee on Intelligence and the House Permanent Select Committee on Intelligence; these 28 pages contain information regarding the material and financial assistance given to the hijackers and their affiliates leading up to the attacks by the Saudi Arabian government. The origins of al-Qaeda can be traced to 1979. Osama bin Laden helped organize Arab mujahideen to resist the Soviets. Under the guidance of Ayman al-Zawahiri, bin Laden became more radical. In 1996, bin Laden issued his first fatwā. In a second fatwā in 1998, bin Laden outlined his objections to American foreign policy with respect to Israel, as well as the continued presence of American troops in Saudi Arabia after the Gulf War.
Bin Laden used Islamic texts to exhort Muslims to attack Americans until the stated grievances are reversed. Muslim legal scholars "have throughout Islamic history unanimously agreed that the jihad is an individual duty if the enemy destroys the Muslim countries", according to bin Laden. Bin Laden orchestrated the attacks and denied involvement but recanted his false statements. Al Jazeera broadcast a statement by bin Laden on September 16, 2001, stating, "I stress that I have not carried out this act, which appears to have been carried out by individuals with their own motivation." In November 2001, U. S. forces recovered a videotape from a destroyed house in Afghanistan. In the video, bin Laden admits foreknowledge of the attacks. On December 27, 2001, a second bin Laden video was released. In the video, he said: It has become clear that the West in general and America in particular have an unspeakable hatred for Islam.... It is the hatred of crusaders. Terrorism against America deserves to be praised because it was a response to injustice, aimed at forcing America to stop its support for Israel, which kills our people....
Radio broadcasting is transmission by radio waves intended to reach a wide audience. Stations can be linked in radio networks to broadcast a common radio format, either in broadcast syndication or simulcast or both; the signal types can be digital audio. The earliest radio stations did not carry audio. For audio broadcasts to be possible, electronic detection and amplification devices had to be incorporated; the thermionic valve was invented in 1904 by the English physicist John Ambrose Fleming. He developed a device he called an "oscillation valve"; the heated filament, or cathode, was capable of thermionic emission of electrons that would flow to the plate when it was at a higher voltage. Electrons, could not pass in the reverse direction because the plate was not heated and thus not capable of thermionic emission of electrons. Known as the Fleming valve, it could be used as a rectifier of alternating current and as a radio wave detector; this improved the crystal set which rectified the radio signal using an early solid-state diode based on a crystal and a so-called cat's whisker.
However, what was still required was an amplifier. The triode was patented on March 4, 1906, by the Austrian Robert von Lieben independent from that, on October 25, 1906, Lee De Forest patented his three-element Audion, it wasn't put to practical use until 1912 when its amplifying ability became recognized by researchers. By about 1920, valve technology had matured to the point where radio broadcasting was becoming viable. However, an early audio transmission that could be termed a broadcast may have occurred on Christmas Eve in 1906 by Reginald Fessenden, although this is disputed. While many early experimenters attempted to create systems similar to radiotelephone devices by which only two parties were meant to communicate, there were others who intended to transmit to larger audiences. Charles Herrold started broadcasting in California in 1909 and was carrying audio by the next year.. In The Hague, the Netherlands, PCGG started broadcasting on November 6, 1919, making it, arguably the first commercial broadcasting station.
In 1916, Frank Conrad, an electrical engineer employed at the Westinghouse Electric Corporation, began broadcasting from his Wilkinsburg, Pennsylvania garage with the call letters 8XK. The station was moved to the top of the Westinghouse factory building in East Pittsburgh, Pennsylvania. Westinghouse relaunched the station as KDKA on November 2, 1920, as the first commercially licensed radio station in America; the commercial broadcasting designation came from the type of broadcast license. The first licensed broadcast in the United States came from KDKA itself: the results of the Harding/Cox Presidential Election; the Montreal station that became CFCF began broadcast programming on May 20, 1920, the Detroit station that became WWJ began program broadcasts beginning on August 20, 1920, although neither held a license at the time. In 1920, wireless broadcasts for entertainment began in the UK from the Marconi Research Centre 2MT at Writtle near Chelmsford, England. A famous broadcast from Marconi's New Street Works factory in Chelmsford was made by the famous soprano Dame Nellie Melba on 15 June 1920, where she sang two arias and her famous trill.
She was the first artist of international renown to participate in direct radio broadcasts. The 2MT station began to broadcast regular entertainment in 1922; the BBC was amalgamated in 1922 and received a Royal Charter in 1926, making it the first national broadcaster in the world, followed by Czech Radio and other European broadcasters in 1923. Radio Argentina began scheduled transmissions from the Teatro Coliseo in Buenos Aires on August 27, 1920, making its own priority claim; the station got its license on November 19, 1923. The delay was due to the lack of official Argentine licensing procedures before that date; this station continued regular broadcasting of entertainment and cultural fare for several decades. Radio in education soon followed and colleges across the U. S. began adding radio broadcasting courses to their curricula. Curry College in Milton, Massachusetts introduced one of the first broadcasting majors in 1932 when the college teamed up with WLOE in Boston to have students broadcast programs.
Broadcasting service is – according to Article 1.38 of the International Telecommunication Union´s Radio Regulations – defined as «A radiocommunication service in which the transmission are intended for direct reception by the general public. This service may include sound transmissions, television transmissions or other types of transmission.» Definitions identical to those contained in the Annexes to the Constitution and Convention of the International Telecommunication Union are marked "" or "" respectively. A radio broadcasting station is associated with wireless transmission, though in practice broadcasting transmission take place using both wires and radio waves; the point of this is that anyone with the appropriate receiving technology can receive the broadcast. In line to ITU Radio Regulations each broadcasting station shall be classified by the service in which it operates permanently or temporarily. Broadcasting by radio takes several forms; these include FM stations. There are several subtypes, namely commercial broadcasting, non-commercial educational public broadcasting and non-profit varieties as well as community radio, student-run campus radio stations, and
The Internet is the global system of interconnected computer networks that use the Internet protocol suite to link devices worldwide. It is a network of networks that consists of private, academic and government networks of local to global scope, linked by a broad array of electronic and optical networking technologies; the Internet carries a vast range of information resources and services, such as the inter-linked hypertext documents and applications of the World Wide Web, electronic mail and file sharing. Some publications no longer capitalize "internet"; the origins of the Internet date back to research commissioned by the federal government of the United States in the 1960s to build robust, fault-tolerant communication with computer networks. The primary precursor network, the ARPANET served as a backbone for interconnection of regional academic and military networks in the 1980s; the funding of the National Science Foundation Network as a new backbone in the 1980s, as well as private funding for other commercial extensions, led to worldwide participation in the development of new networking technologies, the merger of many networks.
The linking of commercial networks and enterprises by the early 1990s marked the beginning of the transition to the modern Internet, generated a sustained exponential growth as generations of institutional and mobile computers were connected to the network. Although the Internet was used by academia since the 1980s, commercialization incorporated its services and technologies into every aspect of modern life. Most traditional communication media, including telephony, television, paper mail and newspapers are reshaped, redefined, or bypassed by the Internet, giving birth to new services such as email, Internet telephony, Internet television, online music, digital newspapers, video streaming websites. Newspaper and other print publishing are adapting to website technology, or are reshaped into blogging, web feeds and online news aggregators; the Internet has enabled and accelerated new forms of personal interactions through instant messaging, Internet forums, social networking. Online shopping has grown exponentially both for major retailers and small businesses and entrepreneurs, as it enables firms to extend their "brick and mortar" presence to serve a larger market or sell goods and services online.
Business-to-business and financial services on the Internet affect supply chains across entire industries. The Internet has no single centralized governance in either technological implementation or policies for access and usage; the overreaching definitions of the two principal name spaces in the Internet, the Internet Protocol address space and the Domain Name System, are directed by a maintainer organization, the Internet Corporation for Assigned Names and Numbers. The technical underpinning and standardization of the core protocols is an activity of the Internet Engineering Task Force, a non-profit organization of loosely affiliated international participants that anyone may associate with by contributing technical expertise. In November 2006, the Internet was included on USA Today's list of New Seven Wonders; when the term Internet is used to refer to the specific global system of interconnected Internet Protocol networks, the word is a proper noun that should be written with an initial capital letter.
In common use and the media, it is erroneously not capitalized, viz. the internet. Some guides specify that the word should be capitalized when used as a noun, but not capitalized when used as an adjective; the Internet is often referred to as the Net, as a short form of network. As early as 1849, the word internetted was used uncapitalized as an adjective, meaning interconnected or interwoven; the designers of early computer networks used internet both as a noun and as a verb in shorthand form of internetwork or internetworking, meaning interconnecting computer networks. The terms Internet and World Wide Web are used interchangeably in everyday speech. However, the World Wide Web or the Web is only one of a large number of Internet services; the Web is a collection of interconnected documents and other web resources, linked by hyperlinks and URLs. As another point of comparison, Hypertext Transfer Protocol, or HTTP, is the language used on the Web for information transfer, yet it is just one of many languages or protocols that can be used for communication on the Internet.
The term Interweb is a portmanteau of Internet and World Wide Web used sarcastically to parody a technically unsavvy user. Research into packet switching, one of the fundamental Internet technologies, started in the early 1960s in the work of Paul Baran and Donald Davies. Packet-switched networks such as the NPL network, ARPANET, the Merit Network, CYCLADES, Telenet were developed in the late 1960s and early 1970s; the ARPANET project led to the development of protocols for internetworking, by which multiple separate networks could be joined into a network of networks. ARPANET development began with two network nodes which were interconnected between the Network Measurement Center at the University of California, Los Angeles Henry Samueli School of Engineering and Applied Science directed by Leonard Kleinrock, the NLS system at SRI International by Douglas Engelbart in Menlo Park, California, on 29 October 1969; the third site was the Culler-Fried Interactive Mathematics Center at the University of California, Santa Barbara, followed by the University of
Music is an art form and cultural activity whose medium is sound organized in time. General definitions of music include common elements such as pitch, rhythm and the sonic qualities of timbre and texture. Different styles or types of music may de-emphasize or omit some of these elements. Music is performed with a vast range of instruments and vocal techniques ranging from singing to rapping; the word derives from Greek μουσική. See glossary of musical terminology. In its most general form, the activities describing music as an art form or cultural activity include the creation of works of music, the criticism of music, the study of the history of music, the aesthetic examination of music. Ancient Greek and Indian philosophers defined music as tones ordered horizontally as melodies and vertically as harmonies. Common sayings such as "the harmony of the spheres" and "it is music to my ears" point to the notion that music is ordered and pleasant to listen to. However, 20th-century composer John Cage thought that any sound can be music, for example, "There is no noise, only sound."The creation, performance and the definition of music vary according to culture and social context.
Indeed, throughout history, some new forms or styles of music have been criticized as "not being music", including Beethoven's Grosse Fuge string quartet in 1825, early jazz in the beginning of the 1900s and hardcore punk in the 1980s. There are many types of music, including popular music, traditional music, art music, music written for religious ceremonies and work songs such as chanteys. Music ranges from organized compositions–such as Classical music symphonies from the 1700s and 1800s, through to spontaneously played improvisational music such as jazz, avant-garde styles of chance-based contemporary music from the 20th and 21st centuries. Music can be divided into genres and genres can be further divided into subgenres, although the dividing lines and relationships between music genres are subtle, sometimes open to personal interpretation, controversial. For example, it can be hard to draw the line between heavy metal. Within the arts, music may be classified as a fine art or as an auditory art.
Music may be played or sung and heard live at a rock concert or orchestra performance, heard live as part of a dramatic work, or it may be recorded and listened to on a radio, MP3 player, CD player, smartphone or as film score or TV show. In many cultures, music is an important part of people's way of life, as it plays a key role in religious rituals, rite of passage ceremonies, social activities and cultural activities ranging from amateur karaoke singing to playing in an amateur funk band or singing in a community choir. People may make music as a hobby, like a teen playing cello in a youth orchestra, or work as a professional musician or singer; the music industry includes the individuals who create new songs and musical pieces, individuals who perform music, individuals who record music, individuals who organize concert tours, individuals who sell recordings, sheet music, scores to customers. The word derives from Greek μουσική. In Greek mythology, the nine Muses were the goddesses who inspired literature and the arts and who were the source of the knowledge embodied in the poetry, song-lyrics, myths in the Greek culture.
According to the Online Etymological Dictionary, the term "music" is derived from "mid-13c. Musike, from Old French musique and directly from Latin musica "the art of music," including poetry." This is derived from the "... Greek mousike " of the Muses," from fem. of mousikos "pertaining to the Muses," from Mousa "Muse". Modern spelling from 1630s. In classical Greece, any art in which the Muses presided, but music and lyric poetry." Music is composed and performed for many purposes, ranging from aesthetic pleasure, religious or ceremonial purposes, or as an entertainment product for the marketplace. When music was only available through sheet music scores, such as during the Classical and Romantic eras, music lovers would buy the sheet music of their favourite pieces and songs so that they could perform them at home on the piano. With the advent of sound recording, records of popular songs, rather than sheet music became the dominant way that music lovers would enjoy their favourite songs. With the advent of home tape recorders in the 1980s and digital music in the 1990s, music lovers could make tapes or playlists of their favourite songs and take them with them on a portable cassette player or MP3 player.
