As jazz spread around the world, it drew on national, regional, and local musical cultures, which gave rise to different styles. New Orleans jazz began in the early 1910s, combining earlier brass band marches, French quadrilles, biguine, ragtime and blues with collective polyphonic improvisation. But jazz did not begin as a single musical tradition in New Orleans or elsewhere. In the 1930s, arranged dance-oriented swing big bands, Kansas City jazz (a hard-swinging, bluesy, improvisational style), and gypsy jazz (a style that emphasized musette waltzes) were the prominent styles. Bebop emerged in the 1940s, shifting jazz from danceable popular music toward a more challenging \"musician's music\" which was played at faster tempos and used more chord-based improvisation. Cool jazz developed near the end of the 1940s, introducing calmer, smoother sounds and long, linear melodic lines.
The mid-1950s saw the emergence of hard bop, which introduced influences from rhythm and blues, gospel, and blues to small groups and particularly to saxophone and piano. Modal jazz developed in the late 1950s, using the mode, or musical scale, as the basis of musical structure and improvisation, as did free jazz, which explored playing without regular meter, beat and formal structures. Jazz-rock fusion appeared in the late 1960s and early 1970s, combining jazz improvisation with rock music's rhythms, electric instruments, and highly amplified stage sound. In the early 1980s, a commercial form of jazz fusion called smooth jazz became successful, garnering significant radio airplay. Other styles and genres abound in the 21st century, such as Latin and Afro-Cuban jazz.
Jazz is difficult to define because it encompasses a wide range of music spanning a period of over 100 years, from ragtime to rock-infused fusion. Attempts have been made to define jazz from the perspective of other musical traditions, such as European music history or African music. But critic Joachim-Ernst Berendt argues that its terms of reference and its definition should be broader, defining jazz as a \"form of art music which originated in the United States through the confrontation of the Negro with European music\" and arguing that it differs from European music in that jazz has a \"special relationship to time defined as 'swing'\". Jazz involves \"a spontaneity and vitality of musical production in which improvisation plays a role\" and contains a \"sonority and manner of phrasing which mirror the individuality of the performing jazz musician\".
A broader definition that encompasses different eras of jazz has been proposed by Travis Jackson: \"it is music that includes qualities such as swing, improvising, group interaction, developing an 'individual voice', and being open to different musical possibilities\". Krin Gibbard argued that \"jazz is a construct\" which designates \"a number of musics with enough in common to be understood as part of a coherent tradition\". Duke Ellington, one of jazz's most famous figures, said, \"It's all music.\"
Although jazz is considered difficult to define, in part because it contains many subgenres, improvisation is one of its defining elements. The centrality of improvisation is attributed to the influence of earlier forms of music such as blues, a form of folk music which arose in part from the work songs and field hollers of African-American slaves on plantations. These work songs were commonly structured around a repetitive call-and-response pattern, but early blues was also improvisational. Classical music performance is evaluated more by its fidelity to the musical score, with less attention given to interpretation, ornamentation, and accompaniment. The classical performer's goal is to play the composition as it was written. In contrast, jazz is often characterized by the product of interaction and collaboration, placing less value on the contribution of the composer, if there is one, and more on the performer. The jazz performer interprets a tune in individual ways, never playing the same composition twice. Depending on the performer's mood, experience, and interaction with band members or audience members, the performer may change melodies, harmonies, and time signatures.
Since the emergence of bebop, forms of jazz that are commercially oriented or influenced by popular music have been criticized. According to Bruce Johnson, there has always been a \"tension between jazz as a commercial music and an art form\". Regarding the Dixieland jazz revival of the 1940s, Black musicians rejected it as being shallow nostalgia entertainment for white audiences. On the other hand, traditional jazz enthusiasts have dismissed bebop, free jazz, and jazz fusion as forms of debasement and betrayal. An alternative view is that jazz can absorb and transform diverse musical styles. By avoiding the creation of norms, jazz allows avant-garde styles to emerge.
For some African Americans, jazz has drawn attention to African-American contributions to culture and history. For others, jazz is a reminder of \"an oppressive and racist society and restrictions on their artistic visions\". Amiri Baraka argues that there is a \"white jazz\" genre that expresses whiteness. White jazz musicians appeared in the Midwest and in other areas throughout the U.S. Papa Jack Laine, who ran the Reliance band in New Orleans in the 1910s, was called \"the father of white jazz\". The Original Dixieland Jazz Band, whose members were white, were the first jazz group to record, and Bix Beiderbecke was one of the most prominent jazz soloists of the 1920s. The Chicago Style was developed by white musicians such as Eddie Condon, Bud Freeman, Jimmy McPartland, and Dave Tough. Others from Chicago such as Benny Goodman and Gene Krupa became leading members of swing during the 1930s. Many bands included both Black and white musicians. These musicians helped change attitudes toward race in the U.S.
When male jazz musicians were drafted during World War II, many all-female bands replaced them. The International Sweethearts of Rhythm, which was founded in 1937, was a popular band that became the first all-female integrated band in the U.S. and the first to travel with the USO, touring Europe in 1945. Women were members of the big bands of Woody Herman and Gerald Wilson. Beginning in the 1950s, many women jazz instrumentalists were prominent, some sustaining long careers. Some of the most distinctive improvisers, composers, and bandleaders in jazz have been women. Trombonist Melba Liston is acknowledged as the first female horn player to work in major bands and to make a real impact on jazz, not only as a musician but also as a respected composer and arranger, particularly through her collaborations with Randy Weston from the late 1950s into the 1990s.
The Jazz Singer with Al Jolson is one example of how Jewish Americans were able to bring jazz, music that African Americans developed, into popular culture. Benny Goodman was a vital Jewish American to the progression of Jazz. Goodman was the leader of a racially integrated band named King of Swing. His jazz concert in the Carnegie Hall in 1938 was the first ever to be played there. The concert was described by Bruce Eder as \"the single most important jazz or popular music concert in history\".
Another influence came from the harmonic style of hymns of the church, which black slaves had learned and incorporated into their own music as spirituals. The origins of the blues are undocumented, though they can be seen as the secular counterpart of the spirituals. However, as Gerhard Kubik points out, whereas the spirituals are homophonic, rural blues and early jazz \"was largely based on concepts of heterophony\".
In the opinion of jazz historian Ernest Borneman, what preceded New Orleans jazz before 1890 was \"Afro-Latin music\", similar to what was played in the Caribbean at the time. A three-stroke pattern known in Cuban music as tresillo is a fundamental rhythmic figure heard in many different slave musics of the Caribbean, as well as the Afro-Caribbean folk dances performed in New Orleans Congo Square and Gottschalk's compositions (for example \"Souvenirs From Havana\" (1859)). Tresillo (shown below) is the most basic and most prevalent duple-pulse rhythmic cell in sub-Saharan African music traditions and the music of the African Diaspora.
Tresillo is heard prominently in New Orleans second line music and in other forms of popular music from that city from the turn of the 20th century to present. \"By and large the simpler African rhythmic patterns survived in jazz ... because they could be adapted more readily to European rhythmic conceptions,\" jazz historian Gunther Schuller observed. \"Some survived, others were discarded as the Europeanization progressed.\"
African-American music began incorporating Afro-Cuban rhythmic motifs in the 19th century when the habanera (Cuban contradanza) gained international popularity. Musicians from Havana and New Orleans would take the twice-daily ferry between both cities to perform, and the habanera quickly took root in the musically fertile Crescent City. John Storm Roberts states that the musical genre habanera \"reached the U.S. twenty years before the first rag was published.\" For the more than quarter-century in which the cakewalk, ragtime, and proto-jazz were forming and developing, the habanera was a consistent part of African-American popular music.
Comparing the music of New Orleans with the music of Cuba, Wynton Marsalis observes that tresillo is the New Orleans \"clavé\", a Spanish word meaning \"code\" or \"key\", as in the key to a puzzle, or mystery. Although the pattern is only half a clave, Marsalis makes the point that the single-celled figure is the guide-pattern of New Orleans music. Jelly Roll Morton called the rhythmic figure the Spanish tinge and considered it an essential ingredient of jazz. 59ce067264
