What is Jazz?


I built deepjazz in 36 hours at a hackathon. It uses Keras & Theano, two deep learning libraries, to generate jazz music. Specifically, it builds a two-layer LSTM, learning from the given MIDI file.

Although some jazz purists protested against the blend of jazz and rock, many jazz innovators crossed over from the contemporary hard bop scene into fusion. I'd been getting bored with the stereotyped changes that were being used, Since the emergence of bebop, forms of jazz that are commercially oriented or influenced by popular music have been criticized. Her vocal style and intonation was inspired greatly by the sound of the instruments she heard and was filled with a profound intensity.

Feb 27,  · For over 30 years, his band The Jazz Messengers launched the careers of a multitude of famous jazz artists, like Benny Golson, Wayne Shorter, Clifford Brown, Curtis Fuller, Horace Silver, Freddie Hubbard, Keith Jarrett, Wynton Marsalis and countless others.

Guajeo is the name for the typical Afro-Cuban ostinato melodies which are commonly used motifs in Latin jazz compositions.

They originated in the genre known as son. Guajeos provide a rhythmic and melodic framework that may be varied within certain parameters, whilst still maintaining a repetitive - and thus "danceable" - structure.

Most guajeos are rhythmically based on clave rhythm. Guajeos are one of the most important elements of the vocabulary of Afro-Cuban descarga jazz-inspired instrumental jams , providing a means of tension and resolution and a sense of forward momentum, within a relatively simple harmonic structure.

The use of multiple, contrapuntal guajeos in Latin jazz facilitates simultaneous collective improvisation based on theme variation. In a way, this polyphonic texture is reminiscent of the original New Orleans style of jazz. For most of its history, Afro-Cuban jazz had been a matter of superimposing jazz phrasing over Cuban rhythms. But by the end of the s, a new generation of New York City musicians had emerged who were fluent in both salsa dance music and jazz, leading to a new level of integration of jazz and Cuban rhythms.

This era of creativity and vitality is best represented by the Gonzalez brothers Jerry congas and trumpet and Andy bass. He incorporated parallel fourths, with McCoy Tyner-type vamps. This occurred in parallel with developments in Cuba [] The first Cuban band of this new wave was Irakere. Their "Chékere-son" introduced a style of "Cubanized" bebop-flavored horn lines that departed from the more angular guajeo-based lines which were typical of Cuban popular music and Latin jazz up until that time.

It was based on Charlie Parker's composition "Billie's Bounce", jumbled together in a way that fused clave and bebop horn lines. Brazilian jazz such as bossa nova is derived from samba , with influences from jazz and other 20th-century classical and popular music styles.

Bossa is generally moderately paced, with melodies sung in Portuguese or English, whilst the related term jazz-samba describes an adaptation of street samba into jazz. Gilberto's initial releases, and the film Black Orpheus , achieved significant popularity in Latin America ; this spread to North America via visiting American jazz musicians.

Post-bop jazz is a form of small-combo jazz derived from earlier bop styles. Generally, the term post-bop is taken to mean jazz from the mid-sixties onwards that assimilates influences from hard bop , modal jazz , the avant-garde and free jazz, without necessarily being immediately identifiable as any of the above.

Much post-bop was recorded for Blue Note Records. Most post-bop artists worked in other genres as well, with a particularly strong overlap with the earlier hard bop. Soul jazz was a development of hard bop which incorporated strong influences from blues , gospel and rhythm and blues to create music for small groups, often the organ trio of Hammond organ , drummer and tenor saxophonist.

Unlike hard bop , soul jazz generally emphasized repetitive grooves and melodic hooks, and improvisations were often less complex than in other jazz styles. It often had a steadier "funk" style groove, which was different from the swing rhythms typical of much hard bop. Horace Silver had a large influence on the soul jazz style, with songs that used funky and often gospel -based piano vamps. There was a resurgence of interest in jazz and other forms of African-American cultural expression during the Black Arts Movement and Black nationalist period of the s and s.

African themes became popular, and many new jazz compositions were given African-related titles: Pianist Randy Weston 's music incorporated African elements, such as in the large-scale suite "Uhuru Africa" with the participation of poet Langston Hughes and "Highlife: Music From the New African Nations. Some musicians, including Pharoah Sanders , Hubert Laws , and Wayne Shorter , began using African instruments such as kalimbas , bells, beaded gourds and other instruments which were not traditional to jazz.

African rhythmic structures are accessed directly by Ron Carter bass and Tony Williams drums via the rhythmic sensibilities of swing. Throughout the piece, the four beats, whether sounded or not, are maintained as the temporal referent. In the example below, the main beats are indicated by slashed noteheads, which do not indicate bass notes. The use of pentatonic scales was another trend associated with Africa. The use of pentatonic scales in Africa probably goes back thousands of years.

McCoy Tyner perfected the use of the pentatonic scale in his solos, [] and also used parallel fifths and fourths, which are common harmonies in West Africa. The minor pentatonic scale is often used in blues improvisation, and like a blues scale, a minor pentatonic scale can be played over all of the chords in a blues.

The following pentatonic lick was played over blues changes by Joe Henderson on Horace Silver 's "African Queen" Jazz pianist, theorist, and educator Mark Levine refers to the scale generated by beginning on the fifth step of a pentatonic scale as the V pentatonic scale.

Levine points out that the V pentatonic scale works for all three chords of the standard II-V-I jazz progression. Accordingly, John Coltrane's " Giant Steps " , with its 26 chords per 16 bars, can be played using only three pentatonic scales. Coltrane studied Nicolas Slonimsky 's Thesaurus of Scales and Melodic Patterns , which contains material that is virtually identical to portions of "Giant Steps". Superimposing the pentatonic scale over "Giant Steps" is not merely a matter of harmonic simplification, but also a sort of "Africanizing" of the piece, which provides an alternate approach for soloing.

Mark Levine observes that when mixed in with more conventional "playing the changes", pentatonic scales provide "structure and a feeling of increased space. In the late s and early s, the hybrid form of jazz-rock fusion was developed by combining jazz improvisation with rock rhythms, electric instruments and the highly amplified stage sound of rock musicians such as Jimi Hendrix and Frank Zappa.

Jazz fusion often uses mixed meters, odd time signatures, syncopation, complex chords, and harmonies. In , Davis fully embraced the electric instrument approach to jazz with In a Silent Way , which can be considered his first fusion album. Composed of two side-long suites edited heavily by producer Teo Macero , this quiet, static album would be equally influential to the development of ambient music. The music I was really listening to in was James Brown , the great guitar player Jimi Hendrix , and a new group who had just come out with a hit record, " Dance to the Music ", Sly and the Family Stone I wanted to make it more like rock.

When we recorded In a Silent Way I just threw out all the chord sheets and told everyone to play off of that. Two contributors to In a Silent Way also joined organist Larry Young to create one of the early acclaimed fusion albums: Davis' Bitches Brew album was his most successful of this era.

Although inspired by rock and funk, Davis' fusion creations were original and brought about a new type of avant-garde, electronic, psychedelic-jazz, as far from pop music as any other Davis work. Pianist Herbie Hancock a Davis alumnus released four albums in the short-lived — psychedelic-jazz subgenre: Mwandishi , Crossings , and Sextant The rhythmic background was a mix of rock, funk, and African-type textures.

Musicians who had previously worked with Davis formed the four most influential fusion groups: Weather Report 's self-titled electronic and psychedelic Weather Report debut album caused a sensation in the jazz world on its arrival in , thanks to the pedigree of the group's members including percussionist Airto Moreira , and their unorthodox approach to music.

The album featured a softer sound than would be the case in later years predominantly using acoustic bass with Shorter exclusively playing soprano saxophone , and with no synthesizers involved , but is still considered a classic of early fusion. It built on the avant-garde experiments which Joe Zawinul and Shorter had pioneered with Miles Davis on Bitches Brew , including an avoidance of head-and-chorus composition in favour of continuous rhythm and movement — but took the music further.

To emphasise the group's rejection of standard methodology, the album opened with the inscrutable avant-garde atmospheric piece "Milky Way", which featured by Shorter's extremely muted saxophone inducing vibrations in Zawinul's piano strings while the latter pedalled the instrument.

Down Beat described the album as "music beyond category", and awarded it Album of the Year in the magazine's polls that year. Weather Report 's subsequent releases were creative funk-jazz works. Although some jazz purists protested against the blend of jazz and rock, many jazz innovators crossed over from the contemporary hard bop scene into fusion.

As well as the electric instruments of rock such as electric guitar, electric bass, electric piano and synthesizer keyboards , fusion also used the powerful amplification, "fuzz" pedals , wah-wah pedals and other effects that were used by s-era rock bands.

Jazz fusion was also popular in Japan, where the band Casiopea released over thirty fusion albums. According to jazz writer Stuart Nicholson, "just as free jazz appeared on the verge of creating a whole new musical language in the s By the mids, the sound known as jazz-funk had developed, characterized by a strong back beat groove , electrified sounds [] and, often, the presence of electronic analog synthesizers. Jazz-funk also draws influences from traditional African music, Afro-Cuban rhythms and Jamaican reggae , notably Kingston bandleader Sonny Bradshaw.

Another feature is the shift of emphasis from improvisation to composition: Early examples are Herbie Hancock's Headhunters band and Miles Davis' On the Corner album, which, in , began Davis' foray into jazz-funk and was, he claimed, an attempt at reconnecting with the young black audience which had largely forsaken jazz for rock and funk.

While there is a discernible rock and funk influence in the timbres of the instruments employed, other tonal and rhythmic textures, such as the Indian tambora and tablas and Cuban congas and bongos, create a multi-layered soundscape.

The album was a culmination of sorts of the musique concrète approach that Davis and producer Teo Macero had begun to explore in the late s. Jazz continued to expand and change, influenced by other types of music such as world music , avant garde classical music and rock and pop. Jazz musicians began to improvise on unusual instruments, such as the jazz harp Alice Coltrane , the electrically amplified and wah-wah pedaled jazz violin Jean-Luc Ponty and the bagpipes Rufus Harley.

The s saw something of a reaction against the fusion and free jazz that had dominated the s. Trumpeter Wynton Marsalis emerged early in the decade, and strove to create music within what he believed was the tradition, rejecting both fusion and free jazz and creating extensions of the small and large forms initially pioneered by artists such as Louis Armstrong and Duke Ellington , as well as the hard bop of the s. It is debatable whether Marsalis' critical and commercial success was a cause or a symptom of the reaction against Fusion and Free Jazz and the resurgence of interest in the kind of jazz pioneered in the s particularly modal jazz and post-bop ; nonetheless there were many other manifestations of a resurgence of traditionalism, even if fusion and free jazz were by no means abandoned and continued to develop and evolve.

For example, several musicians who had been prominent in the fusion genre during the s began to record acoustic jazz once more, including Chick Corea and Herbie Hancock. Other musicians who had experimented with electronic instruments in the previous decade had abandoned them by the s; for example, Bill Evans , Joe Henderson , and Stan Getz.

Even the s music of Miles Davis , although certainly still fusion, adopted a far more accessible and recognisably jazz-oriented approach than his abstract work of the mids, such as a return to a theme-and-solos approach. The emergence of young jazz talent beginning to perform in older, established musicians' groups further impacted the resurgence of traditionalism in the jazz community.

In the s, the groups of Betty Carter and Art Blakey and the Jazz Messengers retained their conservative jazz approaches in the midst of fusion and jazz-rock, and in addition to difficulty booking their acts, struggled to find younger generations of personnel to authentically play traditional styles such as hard bop and bebop. In the late s, however, a resurgence of younger jazz players in Blakey's band began to occur. In the s, in addition to Wynton and Branford Marsalis , the emergence of pianists in the Jazz Messengers such as Donald Brown , Mulgrew Miller , and later, Benny Green , bassists such as Charles Fambrough , Lonnie Plaxico and later, Peter Washington and Essiet Essiet horn players such as Bill Pierce , Donald Harrison and later Javon Jackson and Terence Blanchard emerged as talented jazz musicians, all of whom made significant contributions in later s and s jazz music.

These younger rising stars rejected avant-garde approaches and instead championed the acoustic jazz sound of Charlie Parker , Thelonious Monk and early recordings of the first Miles Davis quintet.

This group of "Young Lions" sought to reaffirm jazz as a high art tradition comparable to the discipline of classical music. In addition, Betty Carter 's rotation of young musicians in her group foreshadowed many of New York's preeminent traditional jazz players later in their careers. Blue Note Records 's O. A similar reaction [ vague ] took place against free jazz. According to Ted Gioia:. Anthony Braxton began recording standards over familiar chord changes.

Cecil Taylor played duets in concert with Mary Lou Williams , and let her set out structured harmonies and familiar jazz vocabulary under his blistering keyboard attack. And the next generation of progressive players would be even more accommodating, moving inside and outside the changes without thinking twice.

Musicians such as David Murray or Don Pullen may have felt the call of free-form jazz, but they never forgot all the other ways one could play African-American music for fun and profit. Pianist Keith Jarrett —whose bands of the s had played only original compositions with prominent free jazz elements—established his so-called 'Standards Trio' in , which, although also occasionally exploring collective improvisation, has primarily performed and recorded jazz standards. Chick Corea similarly began exploring jazz standards in the s, having neglected them for the s.

It passed in the House of Representatives on September 23, , and in the Senate on November 4, In the early s, a commercial form of jazz fusion called "pop fusion" or "smooth jazz" became successful, garnering significant radio airplay in " quiet storm " time slots at radio stations in urban markets across the U.

In general, smooth jazz is downtempo the most widely played tracks are of 90— beats per minute , and has a lead melody-playing instrument saxophone, especially soprano and tenor, and legato electric guitar are popular.

West has countered the often negative perceptions of smooth jazz, stating:. I challenge the prevalent marginalization and malignment of smooth jazz in the standard jazz narrative.

Furthermore, I question the assumption that smooth jazz is an unfortunate and unwelcomed evolutionary outcome of the jazz-fusion era. Instead, I argue that smooth jazz is a long-lived musical style that merits multi-disciplinary analyses of its origins, critical dialogues, performance practice, and reception. Acid jazz developed in the UK in the s and s, influenced by jazz-funk and electronic dance music. Acid jazz often contains various types of electronic composition sometimes including Sampling music or a live DJ cutting and scratching , but it is just as likely to be played live by musicians, who often showcase jazz interpretation as part of their performance.

Ginell of AllMusic considers Roy Ayers "one of the prophets of acid jazz. Nu jazz is influenced by jazz harmony and melodies, and there are usually no improvisational aspects. It can be very experimental in nature and can vary widely in sound and concept. Jazz rap developed in the late s and early s and incorporates jazz influences into hip hop. The groups which made up the Native Tongues Posse tended toward jazzy releases: Rapper Guru 's Jazzmatazz series began in using jazz musicians during the studio recordings.

Alhough jazz rap had achieved little mainstream success, Miles Davis' final album Doo-Bop released posthumously in was based on hip hop beats and collaborations with producer Easy Mo Bee.

Davis' ex-bandmate Herbie Hancock also absorbed hip-hop influences in the mids, releasing the album Dis Is Da Drum in The relaxation of orthodoxy which was concurrent with post-punk in London and New York City led to a new appreciation of jazz. In London, the Pop Group began to mix free jazz and dub reggae into their brand of punk rock. Examples of this style include Lydia Lunch 's Queen of Siam , [] Gray, the work of James Chance and the Contortions who mixed Soul with free jazz and punk [] and the Lounge Lizards [] the first group to call themselves " punk jazz ".

John Zorn took note of the emphasis on speed and dissonance that was becoming prevalent in punk rock, and incorporated this into free jazz with the release of the Spy vs. Spy album in , a collection of Ornette Coleman tunes done in the contemporary thrashcore style. The M-Base movement started in the s, when a loose collective of young African-American musicians in New York which included Steve Coleman , Greg Osby , and Gary Thomas developed a complex but grooving [] sound.

In the s, most M-Base participants turned to more conventional music, but Coleman, the most active participant, continued developing his music in accordance with the M-Base concept. Coleman's audience decreased, but his music and concepts influenced many musicians, according to pianist Vijay Iver and critic Ben Ratlifff of The New York Times. M-Base changed from a movement of a loose collective of young musicians to a kind of informal Coleman "school", [] with a much advanced but already originally implied concept.

Since the s, jazz has been characterized by a pluralism in which no one style dominates, but rather a wide range of styles and genres are popular. Individual performers often play in a variety of styles, sometimes in the same performance.

Pianist Brad Mehldau and The Bad Plus have explored contemporary rock music within the context of the traditional jazz acoustic piano trio, recording instrumental jazz versions of songs by rock musicians.

The Bad Plus have also incorporated elements of free jazz into their music. A firm avant-garde or free jazz stance has been maintained by some players, such as saxophonists Greg Osby and Charles Gayle , while others, such as James Carter , have incorporated free jazz elements into a more traditional framework.

Although jazz-rock fusion reached the height of its popularity in the s, the use of electronic instruments and rock-derived musical elements in jazz continued in the s and s. It received some criticism, however, for its failure to reflect the many distinctive non-American traditions and styles in jazz that had developed, and its limited representation of US developments in the last quarter of the 20th century.

The album heavily featured prominent contemporary jazz artists such as Thundercat [] and redefined jazz rap with a larger focus on improvisation and live soloing rather than simply sampling. In that same year, saxophonist Kamasi Washington released his nearly three-hour long debut, The Epic. Another internet-aided trend of 's jazz is that of extreme reharmonization , inspired by both virtuosic players known for their speed and rhythm such as Art Tatum , as well as players known for their ambitious voicings and chords such as Bill Evans.

Supergroup Snarky Puppy has adopted this trend and has allowed for players like Cory Henry [] to shape the grooves and harmonies of modern jazz soloing. YouTube phenomenon Jacob Collier also gained recognition for his ability to play an incredibly large number of instruments and his ability to use microtones , advanced polyrhythms, and blend a spectrum of genres in his largely homemade production process.

In later years, people would sit and listen to it. After the first recordings of jazz were made in , the music spread widely and developed rapidly. Jazz developed a series of different styles including traditional jazz, swing listen, for example, to Benny Carter, who got his start in swing music, in Benny's Music Class bebop, cool jazz, and jazz? At the same time, jazz spread from the United States to many parts of the world, and today jazz musicians--and jazz festivals--can be found in dozens of nations.

Jazz is one of the United States's greatest exports to the world. Skip to main content. Explore History Visit About. Search only items with images. O Say Can You See? His compositions showcased the skill of each of his players, whom he made sure were not only talented, but characteristically unique like himself.

Mingus was feared for his temper, both on and offstage. Mingus suffered from clinical depression and refused to compromise his musical integrity, which resulted in on-stage eruptions and often the threatening of other band mates.

Despite this, Mingus is one of the most important figures in bebop, bass and jazz history. Art Blakey was a famous American drummer and bandleader who revolutionized the way jazz drums were played. His unique approach to drumming incorporated bits of swing, blues, funk and hard bop; a style which is heard today in drummers everywhere.

Along with Max Roach and Kenny Clarke, he is considered to have invented the modern bebop style of drumming. American jazz trumpet player, singer, composer and bandleader, Gillespie was very significant in the development of bebop and modern jazz.

After spending time in Cuba and coming back to America, Gillespie also greatly helped in the advancement of Afro-Cuban Jazz. He was characterized by his horn rimmed glasses, bent trumpet and uniquely puffy cheeks when playing.

A great improviser, Dizzy added a certain layer of harmonic complexity to his music, something previously unknown in jazz. Remaining true to bebop his entire career, Gillespie is remembered as one of the most influential trumpet players in history. Max Roach is considered to be one of the greatest drummers in history, and was a renowned bebop pioneer.

He is, along with a select few, essentially responsible for the modern style of jazz drumming. Roach performed with amazing style, able to play entire shows solo, showing that, given his incredible skill, he could play and completely satisfy an entire audience while fulfilling the requirements of a solo performance. She wrote few songs, but when she sang, she took on a deep, personal and intimate approach. Her vocal style and intonation was inspired greatly by the sound of the instruments she heard and was filled with a profound intensity.

In that manner, she developed a new style, incorporating the manipulation of phrasing and tempo. Although her delivery may have been somewhat thin and her range fairly limited, there is no doubt that her voice was more powerful than any at the time could have hoped to be. Coltrane had a harsh, strident sound and played with extreme intensity.

Groundbreaking pianist, organist, composer and bandleader, Count Basie led one of the most successful bands in history. Winner of nine Grammy awards, Basie introduced multiple generations of listeners to the big band sound. Basie is also remembered by his colleagues as being considerate, modest, relaxed and enthusiastic.

The tenor saxophone is iconic of bebop and jazz music in general; and there is one person accountable for this:
