See a timeline of jazz's history
Jazz began in 19th-century New Orleans, though its roots go back even further. This timeline situates the music's evolution alongside American and world history, offering an illuminating exploration of the genre.
Jazz is a musical style that originated in the 19th-century American South. Its earliest form combined blues, a folk music that evolved from spirituals, and ragtime, a piano-based dance music, often featuring improvisation. As the Great Migration brought millions of Black Americans from the South into the North and Midwest, jazz began to spread, eventually growing into a national sensation.
Its history through the 20th century included several significant changes that bred distinct subgenres. The 1920s and 1930s brought big band and swing, often played by large orchestras that followed rigid compositions, while the 1940s gave birth to bebop, which rebelled against those styles with complex, improvised melodies. The 1950s and 1960s yielded experiments with modal and free jazz, which continue to influence musicians of all stripes.
Although jazz was once seen as an unserious, even dangerous, youth culture, it has since fallen out of popular culture and is often associated with the intellectual and avant-garde.

Linguists believe the word came from "jasm," which referred to vitality. Its earliest known appearance in print dates back to 1912, referring to a baseball pitcher's curveball. It began being used to describe music a few years later.
The style is when a musician plays a rhythm on the opposite side of the beat. That means notes are played on the "upbeats," or the spaces between the main beats of a musical bar. The effect is music that can sound unpredictable, even if it's been carefully constructed.
The trumpeter argues that jazz's approach to syncopation is part of an American tradition that offers the unexpected, citing Jonas Salk, Mark Twain, and fusion cuisine as parallels.
While jazz musicians are known for their improvisational skills, they rely on years of training and a complex understanding of compositions to inform their improvised solos, using a song's structure and chords to make their in-the-moment choices. Although jazz artists could, in theory, play whatever they wanted, musicians often employ common melodic approaches—such as scalar improvisation and arpeggios—to generate solos.
Similar to blues, folk, and country music, jazz relies on a shared tradition of common songs that its artists learn, cover, and rework in their own unique ways. Jazz musicians are often able to easily improvise with other musicians because they share a knowledge of the songs and their languages.
The city's enslaved people congregated in the city square on Sundays, bringing together the musical traditions of their disparate cultures through drum circles, communal dancing, and call-and-response singing. The rhythmic style that evolved in the area would eventually give rise to ragtime and, subsequently, jazz.

Ragtime was a popular music genre that blended African-American spirituals, European folk songs, and military marches. Blues, brought to New Orleans by free Black people seeking opportunities, allowed musicians to play within basic standards. Jazz combined both forms by merging the syncopated, dance-friendly sounds of ragtime with the soulful, brass-instrumental style of the blues.
The genre—short for "ragged time," a reference to the music's syncopation—was wildly popular at the turn of the 20th century, leading some to deem it morally corrupting and an inferior form. In 1901, the American Federation of Musicians, then the most prominent musicians' union in the country, adopted a resolution designating ragtime as "unmusical rot."
