A CD single is a music single in the form of a compact disc. The standard in the Red Book for the term CD single is an 8cm CD, it now refers to any single recorded onto a CD of any size the CD5, or 5-inch CD single. The format was introduced in the mid-1980s but did not gain its place in the market until the early 1990s. With the rise in digital downloads in the early 2010s, sales of CD singles have decreased. Commercially released CD singles can vary in length from two songs up to six songs like an EP; some contain multiple mixes of one or more songs, in the tradition of 12" vinyl singles, in some cases, they may contain a music video for the single itself as well as a collectible poster. Depending on the nation, there may be limits on the number of songs and total length for sales to count in singles charts. Dire Straits' "Brothers in Arms" is reported to have been the world's first CD single, issued in the UK in two separate singles as a promotional item, one distinguished with a logo for the tour, Live in'85, a second to commemorate the Australian leg of the tour marked Live in'86.
Containing four tracks, it had a limited print run. The first commercially released CD Single was Angeline by John Martyn released on 1 February 1986. CD singles were first made eligible for the UK Singles Chart in 1987, the first number 1 available on the format in that country was "I Wanna Dance with Somebody" by Whitney Houston in May 1987; the Mini CD single CD3 format was created for use for singles in the late 1980s, but met with limited success in the US. The smaller CDs were more successful in Japan and had a resurgence in Europe early this century, marketed as "Pock it" CDs, being small enough to fit in a shirt pocket. By 1989, the CD3 was in decline in the US, it was common in the 1990s for US record companies to release both a two-track CD and a multi-track maxi CD. In the UK, record companies would release two CDs but these consisted of three tracks or more each. During the 1990s, CD single releases became less common in certain countries and were released in smaller editions, as the major record labels feared they were cannibalizing the sales of higher-profit-margin CD albums.
Pressure from record labels made singles charts in some countries become song charts, allowing album cuts to chart based only on airplay, without a single being released. In the US, the Billboard Hot 100 made this change in December 1998, after which few songs were released in the CD single format in the US, but they remained popular in the UK and other countries, where charts were still based on single sales and not radio airplay. At the end of the 1990s, the CD was the biggest-selling single format in the UK, but in the US, the dominant single format was airplay. With the advent of digital music sales, the CD single has been replaced as a distribution format in most countries, most charts now include digital download counts as well as physical single sales. In Australia, the Herald Sun reported the CD single is "set to become extinct". In early July 2009, leading music store JB Hi-Fi ceased stocking CD singles because of declining sales, with copies of the week's No. 1 single selling as few as only 350 copies across all their stores nationwide.
While CD singles no longer maintain their own section of the store, copies are still distributed but placed with the artist's albums. That is predominantly the case for popular Australian artists such as Jessica Mauboy, Kylie Minogue and, most Delta Goodrem, whose then-recent singles were released on CD in limited quantities; the ARIA Singles Chart is now "predominantly compiled from legal downloads", ARIA stopped compiling their physical singles sales chart. "On a Mission" by Gabriella Cilmi was the last CD single to be stocked in Kmart and Big W, who concluded stocking newly released singles. Sanity Entertainment, having resisted the decline for longer than the other major outlets, has ceased selling CD singles. In China and South Korea, CD single releases have been rare since the format was introduced, due of the amount of infringement and illegal file sharing over the internet, most of the time singles have been album cuts chart based only on airplay, but with the advent of digital music the charts have occasionally included digital download counts.
In Greece and Cyprus, the term "CD single" is used to describe an extended play in which there may be anywhere from three to six different tracks. These releases charted on the Greek Singles Chart with songs released as singles; the original CD single is a music single released on a mini Compact Disc that measures 8 cm in diameter, rather than the standard 12 cm. They are manufactured using the same methods as standard full-size CDs, can be played in most standard audio CD players and CD-ROM disc drives; the format was first released in the United States, United Kingdom, France, West Germany, Hong Kong in 1987 as the replacement for the 7-inch single. While mini CDs have fallen out of popularity among most major record labels, they remain a popular, low cost way for independent musicians and groups to release music. Capable of holding up to 20 minutes of music, most mini CD singles contain at least two tracks, ofte
In the music industry, a single is a type of release a song recording of fewer tracks than an LP record or an album. This can be released for sale to the public in a variety of different formats. In most cases, a single is a song, released separately from an album, although it also appears on an album; these are the songs from albums that are released separately for promotional uses such as digital download or commercial radio airplay and are expected to be the most popular. In other cases a recording released. Despite being referred to as a single, singles can include up to as many as three tracks; the biggest digital music distributor, iTunes Store, accepts as many as three tracks less than ten minutes each as a single, as does popular music player Spotify. Any more than three tracks on a musical release or thirty minutes in total running time is either an extended play or, if over six tracks long, an album; when mainstream music was purchased via vinyl records, singles would be released double-sided.
That is to say, they were released with an A-side and B-side, on which two singles would be released, one on each side. Moreover, only the most popular songs from a released album would be released as a single. In more contemporary forms of music consumption, artists release most, if not all, of the tracks on an album as singles; the basic specifications of the music single were set in the late 19th century, when the gramophone record began to supersede phonograph cylinders in commercially produced musical recordings. Gramophone discs were manufactured in several sizes. By about 1910, the 10-inch, 78 rpm shellac disc had become the most used format; the inherent technical limitations of the gramophone disc defined the standard format for commercial recordings in the early 20th century. The crude disc-cutting techniques of the time and the thickness of the needles used on record players limited the number of grooves per inch that could be inscribed on the disc surface, a high rotation speed was necessary to achieve acceptable recording and playback fidelity.
78 rpm was chosen as the standard because of the introduction of the electrically powered, synchronous turntable motor in 1925, which ran at 3600 rpm with a 46:1 gear ratio, resulting in a rotation speed of 78.26 rpm. With these factors applied to the 10-inch format and performers tailored their output to fit the new medium; the 3-minute single remained the standard into the 1960s, when the availability of microgroove recording and improved mastering techniques enabled recording artists to increase the duration of their recorded songs. The breakthrough came with Bob Dylan's "Like a Rolling Stone". Although CBS tried to make the record more "radio friendly" by cutting the performance into halves, separating them between the two sides of the vinyl disc, both Dylan and his fans demanded that the full six-minute take be placed on one side, that radio stations play the song in its entirety; as digital downloading and audio streaming have become more prevalent, it has become possible for every track on an album to be available separately.
The concept of a single for an album has been retained as an identification of a more promoted or more popular song within an album collection. The demand for music downloads skyrocketed after the launch of Apple's iTunes Store in January 2001 and the creation of portable music and digital audio players such as the iPod. In September 1997, with the release of Duran Duran's "Electric Barbarella" for paid downloads, Capitol Records became the first major label to sell a digital single from a well-known artist. Geffen Records released Aerosmith's "Head First" digitally for free. In 2004, Recording Industry Association of America introduced digital single certification due to significant sales of digital formats, with Gwen Stefani's "Hollaback Girl" becoming RIAA's first platinum digital single. In 2013, RIAA incorporated on-demand streams into the digital single certification. Single sales in the United Kingdom reached an all-time low in January 2005, as the popularity of the compact disc was overtaken by the then-unofficial medium of the music download.
Recognizing this, On 17 April 2005, Official UK Singles Chart added the download format to the existing format of physical CD singles. Gnarls Barkley was the first act to reach No.1 on this chart through downloads alone in April 2006, for their debut single "Crazy", released physically the following week. On 1 January 2007 digital downloads became eligible from the point of release, without the need for an accompanying physical. Sales improved in the following years, reaching a record high in 2008 that still proceeded to be overtaken in 2009, 2010 and 2011. Singles have been issued in various formats, including 7-inch, 10-inch, 12-inch vinyl discs. Other, less common, formats include singles on Digital Compact Cassette, DVD, LD, as well as many non-standard sizes of vinyl disc; the most common form of the vinyl single is the 45 or 7-inch. The names are derived from its play speed, 45 rpm, the standard diameter, 7 inches; the 7-inch 45 rpm record was released 31 March 1949 by RCA Victor as a smaller, more durable and higher-fidelity replacement for the 78 rpm shellac discs.

Japan is an island country in East Asia. Located in the Pacific Ocean, it lies off the eastern coast of the Asian continent and stretches from the Sea of Okhotsk in the north to the East China Sea and the Philippine Sea in the south; the kanji that make up Japan's name mean "sun origin", it is called the "Land of the Rising Sun". Japan is a stratovolcanic archipelago consisting of about 6,852 islands; the four largest are Honshu, Hokkaido and Shikoku, which make up about ninety-seven percent of Japan's land area and are referred to as home islands. The country is divided into 47 prefectures in eight regions, with Hokkaido being the northernmost prefecture and Okinawa being the southernmost one; the population of 127 million is the world's tenth largest. 90.7 % of people live in cities. About 13.8 million people live in the capital of Japan. The Greater Tokyo Area is the most populous metropolitan area in the world with over 38 million people. Archaeological research indicates; the first written mention of Japan is in Chinese history texts from the 1st century AD.
Influence from other regions China, followed by periods of isolation from Western Europe, has characterized Japan's history. From the 12th century until 1868, Japan was ruled by successive feudal military shōguns who ruled in the name of the Emperor. Japan entered into a long period of isolation in the early 17th century, ended in 1853 when a United States fleet pressured Japan to open to the West. After nearly two decades of internal conflict and insurrection, the Imperial Court regained its political power in 1868 through the help of several clans from Chōshū and Satsuma – and the Empire of Japan was established. In the late 19th and early 20th centuries, victories in the First Sino-Japanese War, the Russo-Japanese War and World War I allowed Japan to expand its empire during a period of increasing militarism; the Second Sino-Japanese War of 1937 expanded into part of World War II in 1941, which came to an end in 1945 following the Japanese surrender. Since adopting its revised constitution on May 3, 1947, during the occupation led by SCAP, the sovereign state of Japan has maintained a unitary parliamentary constitutional monarchy with an Emperor and an elected legislature called the National Diet.
Japan is a member of the ASEAN Plus mechanism, UN, the OECD, the G7, the G8, the G20, is considered a great power. Its economy is the world's third-largest by nominal GDP and the fourth-largest by purchasing power parity, it is the world's fourth-largest exporter and fourth-largest importer. Japan benefits from a skilled and educated workforce. Although it has renounced its right to declare war, Japan maintains a modern military with the world's eighth-largest military budget, used for self-defense and peacekeeping roles. Japan is a developed country with a high standard of living and Human Development Index, its population enjoys the highest life expectancy and third lowest infant mortality rate in the world, but is experiencing issues due to an aging population and low birthrate. Japan is renowned for its historical and extensive cinema, influential music industry, video gaming, rich cuisine and its major contributions to science and modern technology; the Japanese word for Japan is 日本, pronounced Nihon or Nippon and means "the origin of the sun".
The character nichi means "sun" or "day". The compound therefore means "origin of the sun" and is the source of the popular Western epithet "Land of the Rising Sun"; the earliest record of the name Nihon appears in the Chinese historical records of the Tang dynasty, the Old Book of Tang. At the end of the seventh century, a delegation from Japan requested that Nihon be used as the name of their country; this name may have its origin in a letter sent in 607 and recorded in the official history of the Sui dynasty. Prince Shōtoku, the Regent of Japan, sent a mission to China with a letter in which he called himself "the Emperor of the Land where the Sun rises"; the message said: "Here, I, the emperor of the country where the sun rises, send a letter to the emperor of the country where the sun sets. How are you". Prior to the adoption of Nihon, other terms such as Yamato and Wakoku were used; the term Wa is a homophone of Wo 倭, used by the Chinese as a designation for the Japanese as early as the third century Three Kingdoms period.
Another form of Wa, Wei in Chinese) was used for an early state in Japan called Nakoku during the Han dynasty. However, the Japanese disliked some connotation of Wa 倭, it was therefore replaced with the substitute character Wa, meaning "togetherness, harmony"; the English word Japan derives from the historical Chinese pronunciation of 日本. The Old Mandarin or early Wu Chinese pronunciation of Japan was recorded by Marco Polo as Cipangu. In modern Shanghainese, a Wu dialect, the pronunciation of characters 日本; the old Malay word for Japan, Japun or Japang, was borrowed from a southern coastal Chinese dialect Fukienese or Ningpo – and this Malay word was encountered by Portuguese traders in Southeast Asia in the 16th century. These Early Portuguese traders brought the word
Kylie Ann Minogue known mononymously as Kylie, is an Australian-British singer and actress. She achieved recognition starring in the Australian soap opera Neighbours, where she played tomboy mechanic Charlene Robinson. Appearing in the series for two years, Minogue's character married Scott Robinson in an episode viewed by nearly 20 million people in the United Kingdom, making it one of the most watched Australian TV episodes ever. Since Minogue has been a recording artist and has achieved commercial success and critical acclaim in the entertainment industry. Minogue has been recognised with several honorific nicknames, most notably the "Princess of Pop." She is recognised as the highest-selling Australian artist of all time by the Australian Recording Industry Association. Born and raised in Melbourne, Minogue has worked and lived in the United Kingdom since the 1990s, she released her first studio album Kylie the next year. In 1992, she left PWL and signed with Deconstruction Records where she released her self-titled studio album and Impossible Princess, both of which received positive reviews from critics.
Returning to more mainstream dance-oriented music, Minogue signed to Parlophone and released Light Years. The followup, was a hit in many countries, including the United States; the lead single "Can't Get You Out of My Head" became one of the most successful singles of the 2000s, selling over ten million units. It is recognised as her "signature song" and was named "the catchiest song ever" by Yahoo! Music. Other successful singles by Minogue include "I Should Be So Lucky", "The Loco-Motion", "Especially for You", "Hand on Your Heart", "Better the Devil You Know", "Confide in Me", "Spinning Around", "Love at First Sight", "Slow", "2 Hearts" and "All the Lovers". In 2005, while Minogue was on her Showgirl: The Greatest Hits Tour, she was diagnosed with breast cancer. After treatment, she resumed the tour under the title Showgirl: The Homecoming Tour, which critics viewed as a "triumph". Minogue made her film debut in The Delinquents and portrayed Cammy in Street Fighter. Minogue has appeared in the films Moulin Rouge!, Jack & Diane, Holy Motors.
In 2014, she appeared as a judge on the third series of The Voice Australia. Her other ventures include children's books and fashion; as of 2015, Minogue has had worldwide record sales of more than 80 million. She has mounted several successful and critically acclaimed concert world tours and received a Mo Award for "Australian Entertainer of the Year" for her live performances. Minogue was appointed an Officer of the Order of the British Empire in the 2008 New Year Honours for services to Music, she was appointed by the French government as a Chevalier of the Ordre des Arts et des Lettres for her contribution to the enrichment of French culture. Minogue was awarded an honorary Doctor of Health Science degree by Anglia Ruskin University for her work in raising awareness for breast cancer. In November 2011, on the 25th anniversary of the ARIA Music Awards, she was inducted by the Australian Recording Industry Association into the ARIA Hall of Fame. In December 2016, Billboard ranked her as the 18th most successful dance artist of all-time.
Minogue signed a new global recording contract with BMG Rights Management in early 2017. Her latest album Golden was released on 6 April 2018, debuting at No. 1 in the Australia. Kylie was born to Ronald Charles Minogue and Carol Ann Jones in Melbourne, Australia, on 28 May 1968, her father is a fifth generation Australian, has Irish ancestry, while her mother came from Maesteg, Wales. Jones had lived in Wales until age ten when her mother and father and Denis Jones, decided to move to Australia for a better life. Just before Kylie's birth, Ron qualified as an accountant and worked through several jobs while Carol worked as a professional dancer. Kylie's younger brother, Brendan, is a news cameraman in Australia, while her younger sister Dannii Minogue is a singer and television host; the Minogue family moved around various suburbs in Melbourne to sustain their living expenses, which Kylie found unsettling as a child. After the birth of Dannii, the family moved to South Oakleigh; because money was tight, Ron worked as an accountant at a family-owned car company and Carol worked as a tea lady at a local hospital.
After moving to Surrey Hills, Minogue attended Studfield Primary School before attending Camberwell Primary School. She went on to Camberwell High School. During her schooling years, Minogue found it difficult to make friends, she got her HSC with subjects including English. Minogue described herself as being of "average intelligence" and "quite modest" during her high school years. From the age of 11, Kylie appeared in small roles in soap operas including The Sullivans and Skyways. In 1985, she was cast in one of the lead roles in The Henderson Kids. Minogue took time off school to film The Henderson Kids and while Carol was not impressed, Minogue felt that she needed the independence to make it into the entertainment industry. During filming, co-star Nadine Garner labelled Minogue "fragile" after producers yelled at her for forgetting her lines. Minogue was dropped from the second season of the show after producer Alan Hardy felt the need for her character to be "written off". In retrospect, Hardy stated that removing her from the showing "turned out to be the best thing for her".
Interested in following a career in music, Minogue made a demo tape for the producers of weekly music programme Young Talent Time, which featured Dannii as a regular performer
Anime is hand-drawn and computer animation originating from or associated with Japan. The word anime is the Japanese term for animation. Outside Japan, anime refers to animation from Japan or as a Japanese-disseminated animation style characterized by colorful graphics, vibrant characters and fantastical themes; the culturally abstract approach to the word's meaning may open up the possibility of anime produced in countries other than Japan. For simplicity, many Westerners view anime as a Japanese animation product; some scholars suggest defining anime as or quintessentially Japanese may be related to a new form of Orientalism. The earliest commercial Japanese animation dates to 1917, Japanese anime production has since continued to increase steadily; the characteristic anime art style emerged in the 1960s with the works of Osamu Tezuka and spread internationally in the late twentieth century, developing a large domestic and international audience. Anime is distributed theatrically, by way of television broadcasts, directly to home media, over the Internet.
It is classified into numerous genres targeting diverse broad and niche audiences. Anime is a diverse art form with distinctive production methods and techniques that have been adapted over time in response to emergent technologies, it consists of an ideal story-telling mechanism, combining graphic art, characterization and other forms of imaginative and individualistic techniques. The production of anime focuses less on the animation of movement and more on the realism of settings as well as the use of camera effects, including panning and angle shots. Being hand-drawn, anime is separated from reality by a crucial gap of fiction that provides an ideal path for escapism that audiences can immerse themselves into with relative ease. Diverse art styles are used and character proportions and features can be quite varied, including characteristically large emotive or realistically sized eyes; the anime industry consists of over 430 production studios, including major names like Studio Ghibli and Toei Animation.
Despite comprising only a fraction of Japan's domestic film market, anime makes up a majority of Japanese DVD sales. It has seen international success after the rise of English-dubbed programming; this rise in international popularity has resulted in non-Japanese productions using the anime art style. Whether these works are anime-influenced animation or proper anime is a subject for debate amongst fans. Japanese anime accounts for 60% of the world's animated cartoon television shows, as of 2016. Anime is an art form animation, that includes all genres found in cinema, but it can be mistakenly classified as a genre. In Japanese, the term anime is used as a blanket term to refer to all forms of animation from around the world. In English, anime is more restrictively used to denote a "Japanese-style animated film or television entertainment" or as "a style of animation created in Japan"; the etymology of the word anime is disputed. The English term "animation" is written in Japanese katakana as アニメーション and is アニメ in its shortened form.
The pronunciation of anime in Japanese differs from pronunciations in other languages such as Standard English, which has different vowels and stress with regards to Japanese, where each mora carries equal stress. As with a few other Japanese words such as saké, Pokémon, Kobo Abé, English-language texts sometimes spell anime as animé, with an acute accent over the final e, to cue the reader to pronounce the letter, not to leave it silent as Standard English orthography may suggest; some sources claim that anime derives from the French term for animation dessin animé, but others believe this to be a myth derived from the French popularity of the medium in the late 1970s and 1980s. In English, anime—when used as a common noun—normally functions as a mass noun. Prior to the widespread use of anime, the term Japanimation was prevalent throughout the 1970s and 1980s. In the mid-1980s, the term anime began to supplant Japanimation. In general, the latter term now only appears in period works where it is used to distinguish and identify Japanese animation.
The word anime has been criticised, e.g. in 1987, when Hayao Miyazaki stated that he despised the truncated word anime because to him it represented the desolation of the Japanese animation industry. He equated the desolation with animators lacking motivation and with mass-produced, overly expressionistic products relying upon a fixed iconography of facial expressions and protracted and exaggerated action scenes but lacking depth and sophistication in that they do not attempt to convey emotion or thought; the first format of anime was theatrical viewing which began with commercial productions in 1917. The animated flips were crude and required played musical components before adding sound and vocal components to the production. On July 14, 1958, Nippon Television aired Mogura no Abanchūru, both the first televised and first color anime to debut, it wasn't until the 1960s when the first televised series were broadcast and it has remained a popular medium since. Works released in a direct to video format are called "original video animation" or "original animation video".
The emergence of the Internet has led some animators to distribute works online in a format called "original net anime". The home distribution of anime releases were
A record producer or music producer oversees and manages the sound recording and production of a band or performer's music, which may range from recording one song to recording a lengthy concept album. A producer has varying roles during the recording process, they may gather musical ideas for the project, collaborate with the artists to select cover tunes or original songs by the artist/group, work with artists and help them to improve their songs, lyrics or arrangements. A producer may also: Select session musicians to play rhythm section accompaniment parts or solos Co-write Propose changes to the song arrangements Coach the singers and musicians in the studioThe producer supervises the entire process from preproduction, through to the sound recording and mixing stages, and, in some cases, all the way to the audio mastering stage; the producer may perform these roles themselves, or help select the engineer, provide suggestions to the engineer. The producer may pay session musicians and engineers and ensure that the entire project is completed within the record label's budget.
A record producer or music producer has a broad role in overseeing and managing the recording and production of a band or performer's music. A producer has many roles that may include, but are not limited to, gathering ideas for the project, composing the music for the project, selecting songs or session musicians, proposing changes to the song arrangements, coaching the artist and musicians in the studio, controlling the recording sessions, supervising the entire process through audio mixing and, in some cases, to the audio mastering stage. Producers often take on a wider entrepreneurial role, with responsibility for the budget, schedules and negotiations. Writer Chris Deville explains it, "Sometimes a producer functions like a creative consultant — someone who helps a band achieve a certain aesthetic, or who comes up with the perfect violin part to complement the vocal melody, or who insists that a chorus should be a bridge. Other times a producer will build a complete piece of music from the ground up and present the finished product to a vocalist, like Metro Boomin supplying Future with readymade beats or Jack Antonoff letting Taylor Swift add lyrics and melody to an otherwise-finished “Out Of The Woods.”The artist of an album may not be a record producer or music producer for his/her album.
While both contribute creatively, the official credit of "record producer" may depend on the record contract. Christina Aguilera, for example, did not receive record producer credits until many albums into her career. In the 2010s, the producer role is sometimes divided among up to three different individuals: executive producer, vocal producer and music producer. An executive producer oversees project finances, a vocal producers oversees the vocal production, a music producer oversees the creative process of recording and mixings; the music producer is often a competent arranger, musician or songwriter who can bring fresh ideas to a project. As well as making any songwriting and arrangement adjustments, the producer selects and/or collaborates with the mixing engineer, who takes the raw recorded tracks and edits and modifies them with hardware and software tools to create a stereo or surround sound "mix" of all the individual voices sounds and instruments, in turn given further adjustment by a mastering engineer for the various distribution media.
The producer oversees the recording engineer who concentrates on the technical aspects of recording. Noted producer Phil Ek described his role as "the person who creatively guides or directs the process of making a record", like a director would a movie. Indeed, in Bollywood music, the designation is music director; the music producer's job is to create and mold a piece of music. The scope of responsibility may be one or two songs or an artist's entire album – in which case the producer will develop an overall vision for the album and how the various songs may interrelate. At the beginning of record industry, the producer role was technically limited to record, in one shot, artists performing live; the immediate predecessors to record producers were the artists and repertoire executives of the late 1920s and 1930s who oversaw the "pop" product and led session orchestras. That was the case of Ben Selvin at Columbia Records, Nathaniel Shilkret at Victor Records and Bob Haring at Brunswick Records.
By the end of the 1930s, the first professional recording studios not owned by the major companies were established separating the roles of A&R man and producer, although it wouldn't be until the late 1940s when the term "producer" became used in the industry. The role of producers changed progressively over the 1960s due to technology; the development of multitrack recording caused a major change in the recording process. Before multitracking, all the elements of a song had to be performed simultaneously. All of these singers and musicians had to be assembled in a large studio where the performance was recorded. With multitrack recording, the "bed tracks" (rhythm section accompaniment parts such as the bassline and rhythm guitar could be recorded first, the vocals and solos could be added using as many "takes" as necessary, it was no longer necessary to get all the players in the studio at the same time. A pop band could record their backing tracks one week, a horn section could be brought in a week to add horn shots and punches, a string section could be brought in a week after that.
Multitrack recording had another pro
A music genre is a conventional category that identifies some pieces of music as belonging to a shared tradition or set of conventions. It is to be distinguished from musical form and musical style, although in practice these terms are sometimes used interchangeably. Academics have argued that categorizing music by genre is inaccurate and outdated. Music can be divided into different genres in many different ways; the artistic nature of music means that these classifications are subjective and controversial, some genres may overlap. There are varying academic definitions of the term genre itself. In his book Form in Tonal Music, Douglass M. Green distinguishes between form, he lists madrigal, canzona and dance as examples of genres from the Renaissance period. To further clarify the meaning of genre, Green writes, "Beethoven's Op. 61 and Mendelssohn's Op. 64 are identical in genre – both are violin concertos – but different in form. However, Mozart's Rondo for Piano, K. 511, the Agnus Dei from his Mass, K. 317 are quite different in genre but happen to be similar in form."
Some, like Peter van der Merwe, treat the terms genre and style as the same, saying that genre should be defined as pieces of music that share a certain style or "basic musical language." Others, such as Allan F. Moore, state that genre and style are two separate terms, that secondary characteristics such as subject matter can differentiate between genres. A music genre or subgenre may be defined by the musical techniques, the style, the cultural context, the content and spirit of the themes. Geographical origin is sometimes used to identify a music genre, though a single geographical category will include a wide variety of subgenres. Timothy Laurie argues that since the early 1980s, "genre has graduated from being a subset of popular music studies to being an ubiquitous framework for constituting and evaluating musical research objects". Among the criteria used to classify musical genres are the trichotomy of art and traditional musics. Alternatively, music can be divided on three variables: arousal and depth.
Arousal reflects the energy level of the music. These three variables help explain why many people like similar songs from different traditionally segregated genres. Musicologists have sometimes classified music according to a trichotomic distinction such as Philip Tagg's "axiomatic triangle consisting of'folk','art' and'popular' musics", he explains that each of these three is distinguishable from the others according to certain criteria. The term art music refers to classical traditions, including both contemporary and historical classical music forms. Art music exists in many parts of the world, it emphasizes formal styles that invite technical and detailed deconstruction and criticism, demand focused attention from the listener. In Western practice, art music is considered a written musical tradition, preserved in some form of music notation rather than being transmitted orally, by rote, or in recordings, as popular and traditional music are. Most western art music has been written down using the standard forms of music notation that evolved in Europe, beginning well before the Renaissance and reaching its maturity in the Romantic period.
The identity of a "work" or "piece" of art music is defined by the notated version rather than by a particular performance, is associated with the composer rather than the performer. This is so in the case of western classical music. Art music may include certain forms of jazz, though some feel that jazz is a form of popular music. Sacred Christian music forms an important part of the classical music tradition and repertoire, but can be considered to have an identity of its own; the term popular music refers to any musical style accessible to the general public and disseminated by the mass media. Musicologist and popular music specialist Philip Tagg defined the notion in the light of sociocultural and economical aspects: Popular music, unlike art music, is conceived for mass distribution to large and socioculturally heterogeneous groups of listeners and distributed in non-written form, only possible in an industrial monetary economy where it becomes a commodity and in capitalist societies, subject to the laws of'free' enterprise... it should ideally sell as much as possible.
Popular music is found on most commercial and public service radio stations, in most commercial music retailers and department stores, in movie and television soundtracks. It is noted on the Billboard charts and, in addition to singer-songwriters and composers, it involves music producers more than other genres do; the distinction between classical and popular music has sometimes been blurred in marginal areas such as minimalist music and light classics.
