An album is a collection of audio recordings issued as a collection on compact disc, audio tape, or another medium. Albums of recorded music were developed in the early 20th century as individual 78-rpm records collected in a bound book resembling a photograph album. Vinyl LPs are still issued, though album sales in the 21st-century have focused on CD and MP3 formats; the audio cassette was a format used alongside vinyl from the 1970s into the first decade of the 2000s. An album may be recorded in a recording studio, in a concert venue, at home, in the field, or a mix of places; the time frame for recording an album varies between a few hours to several years. This process requires several takes with different parts recorded separately, brought or "mixed" together. Recordings that are done in one take without overdubbing are termed "live" when done in a studio. Studios are built to absorb sound, eliminating reverberation, so as to assist in mixing different takes. Recordings, including live, may contain sound effects, voice adjustments, etc..
With modern recording technology, musicians can be recorded in separate rooms or at separate times while listening to the other parts using headphones. Album covers and liner notes are used, sometimes additional information is provided, such as analysis of the recording, lyrics or librettos; the term "album" was applied to a collection of various items housed in a book format. In musical usage the word was used for collections of short pieces of printed music from the early nineteenth century. Collections of related 78rpm records were bundled in book-like albums; when long-playing records were introduced, a collection of pieces on a single record was called an album. An album, in ancient Rome, was a board chalked or painted white, on which decrees and other public notices were inscribed in black, it was from this that in medieval and modern times album came to denote a book of blank pages in which verses, sketches and the like are collected. Which in turn led to the modern meaning of an album as a collection of audio recordings issued as a single item.
In the early nineteenth century "album" was used in the titles of some classical music sets, such as Schumann's Album for the Young Opus 68, a set of 43 short pieces. When 78rpm records came out, the popular 10-inch disc could only hold about three minutes of sound per side, so all popular recordings were limited to around three minutes in length. Classical-music and spoken-word items were released on the longer 12-inch 78s, about 4–5 minutes per side. For example, in 1924, George Gershwin recorded a drastically shortened version of the seventeen-minute Rhapsody in Blue with Paul Whiteman and His Orchestra, it ran for 8m 59s. Deutsche Grammophon had produced an album for its complete recording of the opera Carmen in 1908. German record company Odeon released the Nutcracker Suite by Tchaikovsky in 1909 on 4 double-sided discs in a specially designed package; this practice of issuing albums does not seem to have been taken up by other record companies for many years. By about 1910, bound collections of empty sleeves with a paperboard or leather cover, similar to a photograph album, were sold as record albums that customers could use to store their records.
These albums came in both 12-inch sizes. The covers of these bound books were wider and taller than the records inside, allowing the record album to be placed on a shelf upright, like a book, suspending the fragile records above the shelf and protecting them. In the 1930s, record companies began issuing collections of 78 rpm records by one performer or of one type of music in specially assembled albums with artwork on the front cover and liner notes on the back or inside cover. Most albums included three or four records, with two sides each, making six or eight compositions per album; the 12-inch LP record, or 33 1⁄3 rpm microgroove vinyl record, is a gramophone record format introduced by Columbia Records in 1948. A single LP record had the same or similar number of tunes as a typical album of 78s, it was adopted by the record industry as a standard format for the "album". Apart from minor refinements and the important addition of stereophonic sound capability, it has remained the standard format for vinyl albums.
The term "album" was extended to other recording media such as Compact audio cassette, compact disc, MiniDisc, digital albums, as they were introduced. As part of a trend of shifting sales in the music industry, some observers feel that the early 21st century experienced the death of the album. While an album may contain as many or as few tracks as required, in the United States, The Recording Academy's rules for Grammy Awards state that an album must comprise a minimum total playing time of 15 minutes with at least five distinct tracks or a minimum total playing time of 30 minutes with no minimum track requirement. In the United Kingdom, the criteria for the UK Albums Chart is that a recording counts as an "album" i
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. Background music for films/movies draws on both traditions. In this respect, music is like fiction, which draws a distinction between literary fiction and popular fiction, not always precise. Country music known as country and western, hillbilly music, is a genre of popular music that originated in the southern United States in the early 1920s; the polka is a Czech dance and genre of dance music familiar throughout Europe and the Americas. 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 particular
A disc jockey abbreviated as DJ, is a person who plays existing recorded music for a live audience. Most common types of DJs include radio DJ, club DJ who performs at a nightclub or music festival and turntablist who uses record players turntables, to manipulate sounds on phonograph records; the disc in disc jockey referred to gramophone records, but now DJ is used as an all-encompassing term to describe someone who mixes recorded music from any source, including cassettes, CDs or digital audio files on a CDJ or laptop. The title DJ is used by DJs in front of their real names or adopted pseudonyms or stage names. In recent years it has become common for DJs to be featured as the credited artist on tracks they produced despite having a guest vocalist that performs the entire song: like for example Uptown Funk. DJs use audio equipment that can play at least two sources of recorded music and mix them together to create seamless transitions between recordings and develop unique mixes of songs; this involves aligning the beats of the music sources so their rhythms do not clash when played together or to enable a smooth transition from one song to another.
DJs use specialized DJ mixers, small audio mixers with crossfader and cue functions to blend or transition from one song to another. Mixers are used to pre-listen to sources of recorded music in headphones and adjust upcoming tracks to mix with playing music. DJ software can be used with a DJ controller device to mix audio files on a computer instead of a console mixer. DJs may use a microphone to speak to the audience; the "disc" in "disc jockey" referred to gramophone records, but now "DJ" is used as an all-encompassing term to describe someone who mixes recorded music from any source, including vinyl records, cassettes, CDs, or digital audio files stored on USB stick or laptop. DJs perform for a live audience in a nightclub or dance club or a TV, radio broadcast audience, or in the 2010s, an online radio audience. DJs create mixes and tracks that are recorded for sale and distribution. In hip hop music, DJs may create beats, using percussion breaks and other musical content sampled from pre-existing records.
In hip hop, rappers and MCs use. DJs use equipment that can play at least two sources of recorded music and mix them together; this allows the DJ to create seamless transitions between recordings and develop unique mixes of songs. This involves aligning the beats of the music sources so their rhythms do not clash when they are played together, either so two records can be played at the same time, or to enable the DJ to make a smooth transition from one song to another. An important tool for DJs is the specialized DJ mixer, a small audio mixer with a crossfader and cue functions; the crossfader enables the DJ to transition from one song to another. The cue knobs or switches allow the DJ to listen to a source of recorded music in headphones before playing it for the live club or broadcast audience. Previewing the music in headphones helps the DJ pick the next track they want to play, cue up the track to the desired starting location, align the two tracks' beats in traditional situations where auto sync technology is not being used.
This process ensures that the selected song will mix well with the playing music. DJs may use a microphone to speak to the audience; the title "DJ" is commonly used by DJs in front of their real names or adopted pseudonyms or stage names as a title to denote their profession. Some DJs focus on creating a good mix of songs for the club dancers or radio audience. Other DJs use turntablism techniques such as scratching, in which the DJ or turntablist manipulates the record player turntable to create new rhythms and sounds. DJs need to have a mixture of artistic and technical skills for their profession, because they have to understand both the creative aspects of making new musical beats and tracks, the technical aspects of using mixing consoles, professional audio equipment, and, in the 2010s, digital audio workstations and other computerized music gear. In many types of DJing, including club DJing and radio/TV DJing, a DJ has to have charisma and develop a good rapport with the audience. Professional DJs specialize in a specific genre of music, such as house music or hip hop music.
DJs have an extensive knowledge about the music they specialize in. Many DJs are avid music collectors of rare or obscure tracks and records. Radio DJs or radio personalities introduce and play music broadcast on AM, FM, digital or Internet radio stations. Club DJs referred as DJs in general, play music at musical events, such as parties at music venues or bars, music festivals and private events. Club DJs mix music recordings from two or more sources using different mixing techniques in order to produce non-stopping flow of music. One key technique used for seamlessly transitioning from one song to another is beatmatching. A DJ who plays and mixes one specific music genre is given the title of that genre; the quality of a DJ performance consists of two main features: technical skills, or how well can DJ operate the equipment and produce sm
Hip hop music
Hip hop music called hip-hop or rap music, is a music genre developed in the United States by inner-city African Americans in the late 1970s which consists of a stylized rhythmic music that accompanies rapping, a rhythmic and rhyming speech, chanted. It developed as part of hip hop culture, a subculture defined by four key stylistic elements: MCing/rapping, DJing/scratching with turntables, break dancing, graffiti writing. Other elements include sampling beats or bass lines from records, rhythmic beatboxing. While used to refer to rapping, "hip hop" more properly denotes the practice of the entire subculture; the term hip hop music is sometimes used synonymously with the term rap music, though rapping is not a required component of hip hop music. Hip hop as both a musical genre and a culture was formed during the 1970s when block parties became popular in New York City among African-American youth residing in the Bronx; however hip-hop music did not get recorded for the radio or television to play until 1979 due to poverty during hip-hop's birth and lack of acceptance outside ghetto neighborhoods.
At block parties DJs played percussive breaks of popular songs using two turntables and a DJ mixer to be able to play breaks from two copies of the same record, alternating from one to the other and extending the "break". Hip hop's early evolution occurred as sampling technology and drum machines became available and affordable. Turntablist techniques such as scratching and beatmatching developed along with the breaks and Jamaican toasting, a chanting vocal style, was used over the beats. Rapping developed as a vocal style in which the artist speaks or chants along rhythmically with an instrumental or synthesized beat. Notable artists at this time include DJ Kool Herc, Grandmaster Flash and The Furious Five, Fab Five Freddy, Marley Marl, Afrika Bambaataa, Kool Moe Dee, Kurtis Blow, Doug E. Fresh, Warp 9, The Fat Boys, Spoonie Gee; the Sugarhill Gang's 1979 song "Rapper's Delight" is regarded to be the first hip hop record to gain widespread popularity in the mainstream. The 1980s marked the diversification of hip hop.
Prior to the 1980s, hip hop music was confined within the United States. However, during the 1980s, it began to spread to music scenes in dozens of countries, many of which mixed hip hop with local styles to create new subgenres. New school hip hop was the second wave of hip hop music, originating in 1983–84 with the early records of Run-D. M. C. and LL Cool J. The Golden age hip hop period was an innovative period between the early 1990s. Notable artists from this era include the Juice Crew, Public Enemy, Eric B. & Rakim, Boogie Down Productions and KRS-One, EPMD, Slick Rick, Beastie Boys, Kool G Rap, Big Daddy Kane, Ultramagnetic MCs, De La Soul, A Tribe Called Quest. Gangsta rap is a subgenre of hip hop that focuses on the violent lifestyles and impoverished conditions of inner-city African-American youth. Schoolly D, N. W. A, Ice-T, Ice Cube, the Geto Boys are key founding artists, known for mixing the political and social commentary of political rap with the criminal elements and crime stories found in gangsta rap.
In the West Coast hip hop style, G-funk dominated mainstream hip hop for several years during the 1990s with artists such as Dr. Dre and Snoop Dogg. East Coast hip hop in the early to mid 1990s was dominated by the Afrocentric jazz rap and alternative hip hop of the Native Tongues posse as well as the hardcore rap of artists such as Mobb Deep, Wu-Tang Clan, Onyx. East Coast hip hop had gangsta rap musicians such as Kool G Rap and the Notorious B. I. G.. In the 1990s, hip hop began to diversify with other regional styles emerging, such as Southern rap and Atlanta hip hop. At the same time, hip hop continued to be assimilated into other genres of popular music, examples being neo soul and nu metal. Hip hop became a best-selling genre in the mid-1990s and the top selling music genre by 1999; the popularity of hip hop music continued through the 2000s, with hip hop influences increasingly finding their way into mainstream pop. The United States saw the success of regional styles such as crunk, a Southern genre that emphasized the beats and music more than the lyrics.
Starting in 2005, sales of hip hop music in the United States began to wane. During the mid-2000s, alternative hip hop secured a place in the mainstream, due in part to the crossover success of artists such as OutKast and Kanye West. During the late 2000s and early 2010s, rappers such as Lil Wayne, Soulja Boy, B.o. B were the most popular rappers. During the 2010s, rappers such as Drake, Nicki Minaj, J. Cole, Kendrick Lamar all have been popular. Trap, a subgenre of hip hop has been popular during the 2010s with hip hop artists and hip hop music groups such as Migos, Travis Scott, Kodak Black; the creation of the term hip hop is credited to Keith Cowboy, rapper with Grandmaster Flash and the Furious Five. However, Lovebug Starski, Keith Cowboy, DJ Hollywood used the term when the music was still known as disco rap, it is believed that Cowboy created the term while teasing a friend who had just joined the U. S. Army, by scat singing the words "hip/hop/hip/hop" in a way that mimicked the rhythmic cadence of soldiers marching.
Cowboy worked the "hip hop" cadence into a part of his stage performance, used by other artists such as The Sugarhi
