Jazz improvisation isn't entirely spontaneous

Jazz musicians use different melodic approaches to produce improvised performances

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.

Jazz improvisations are often based on well-known standards

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.

A lot of jazz relies on syncopation

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.

Jelly Roll Morton claimed he invented jazz, though experts disagree

The pianist and arranger was one of the genre's biggest names in the early 20th century, though very few believed him when he claimed he had invented the music in 1902. One of his biggest contributions to the genre was a 1938 session with ethnomusicologist Alan Lomax, who recorded nearly 8 hours of music and stories that have become an essential part of the music's history.

Jazz brought together ragtime and blues

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.

Coltrane's 'Giant Steps' pushed the limits of jazz

The saxophonist's 1960 recording features chord progressions that have become known as the "Coltrane Changes." Improvising over them is remarkably difficult and has become a rite of passage for jazz musicians.

Free jazz embraced the avant-garde

Ornette Coleman's 1959 album "The Shape of Jazz to Come" abandoned traditional notions of melody and structure, inadvertently creating "free jazz," a subgenre that embraced absolute musical freedom and gained popularity in the countercultural 1960s.

Beats emphasized the importance of 'spontaneous prose'

Beat writer Jack Kerouac believed literature should aim to be more like jazz, using improvisation to burrow down to the root of the subconscious.

How smooth jazz took over the '90s

As jazz entered the '70s, it was at a crossroads. While the genre's figureheads explored fusion and free jazz, which intentionally flouted mainstream convention, other artists began veering towards pop. Eventually, that sound would be called "smooth jazz."

Jazz was an integral part of the Harlem Renaissance

The Great Migration transformed New York City's Harlem neighborhood into the epicenter of Black American art, with artists such as Duke Ellington, Louis Armstrong, and Bessie Smith regularly performing. The music not only provided the backbeat to the cultural scene—it often influenced it, with Harlem Renaissance poets, in particular, inspired by jazz's approach to rhythm and improvisation.

Some critics argue bebop and free jazz led to jazz's decline in popularity

Although jazz was once a popular art form, it has largely been confined to the margins of pop culture, with many of the genre's current bestselling albums from previous decades. Some critics argue that this is because the music betrayed its position as dance music and focused instead on musical proficiency.

Jazz built the template for hip-hop

Hip-hop was born out of obscure samples, including many that were taken from the annals of jazz. That style was especially popular in rap's early eras, with the subgenre "jazz rap" becoming an accurate descriptor for New York groups like A Tribe Called Quest and Gangstarr.

Miles Davis' 'Kind of Blue' changed the genre by pioneering modal jazz

Davis was an adept bebop trumpet player, but he grew tired of the style. With 1959's "Kind of Blue," he pioneered a new style of jazz, called modal jazz, that focused less on improvising on chord progressions and more on open, tone-based expression.

Read a Langston Hughes poem on 'Jazz as Communication'

The essay, delivered in 1956 at the Newport Jazz Festival, offers a poetic take on defining jazz, suggesting that it is the root of both literature and music. “Jazz is a great big sea,” he says. “It washes up all kinds of fish and shells and spume and waves with a steady old beat, or off-beat.”

New Orleans' Congo Square birthed what would become jazz

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.

Bebop's freedom inspired the Beat Generation

The jazz style took off in the 1940s, mesmerizing listeners with its wild, improvised solos. It had a particular impact on the writers of the Beat Generation, including Jack Kerouac and Allen Ginsberg, who saw in bebop's freedom a model for what they could achieve through the written word. Beat writers like Lawrence Ferlighetti and Kenneth Rexroth even incorporated live jazz in their poetry readings.

Hughes' 'Black Nativity' reworked the Christmas story through jazz improvisation

Although he’s primarily known as a poet, Langston Hughes was also a popular playwright.

Jazz's popularity inspired a moral panic

When jazz exploded in the 1920s, some believed the music's sudden popularity was the sign of a rotten nation, with one 1920 address at the University of Wisconsin proclaiming, "We are in deadly fear of the Jazz Devil, the demon which is consuming the country." Often, the connections were racialized, with columnists and preachers suggesting that jazz's Black artists were attempting to degrade white America.

Playing music enhances the creation, storage, and retrieval of memories

Scans of the brains of individuals who play instruments have shown enhanced connectivity between multiple brain regions—visual, auditory, and motor cortices—and the corpus callosum, which connects the two brain hemispheres. These complex connections are strengthened through practice and then used in other activities that involve both logic and creativity. The brains of musicians also appear to give experiences multiple types of memory tags, such as audio, emotional, and conceptual, improving their processing.

Western swing merged country with jazz

For as long as country music has been set to record, its artists have experimented with the genre’s boundaries. Look no further than this track from 1946, Bob Wills’ “Roly Poly.” The song is a classic example of Western swing, a country subgenre that blended country and jazz.
