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.

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.

Jazz improvisation isn't entirely spontaneous

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.

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.

Jean-Paul Sartre was amazed by American jazz

The French philosopher wrote about a 1947 trip to a New York jazz club as a transcendent experience, describing the magic of the relationship between performer and audience: "You shout, they shriek, they whistle, they are possessed, you are possessed."

Essential pipes, sewers, and cables lie buried beneath New York City

The Department of Design and Construction offers a tour of its work sites, explaining the complex systems that exist underground. Gas, electrical, telecom pipes, and many others, sprawl out underneath the entire city, with dozens of maps that help workers know where they're placed. This layout is unusual compared to the rest of the country, where wires are often present and visible above ground.

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.

Arnold Schoenberg's atonal music influenced generations of musicians who followed.

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.”

The Great Migration spread jazz to various parts of the country

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.

Music was a profound inspiration for Basquiat

The prolific artist loved music, obsessing over David Bowie, Aretha Franklin, and numerous jazz figures. Many of his favorites appeared in his paintings, creating a body of work that also acts as a glossary of influences. Below is a 1984 portrait of Max Roach, the jazz drummer. (Some readers may experience a paywall.)

In the '70s, graffiti moved to subway cars

Unlike static walls, the silver cars moved throughout the city, like a canvas in perpetual motion. That made them highly desired by graffiti artists, especially because tagging them was considerably more difficult and, in turn, more impressive than a simple tag in an alley.

How Spotify creates niche genres

One of Spotify's most recognizable features is its playlists. The provider offers an endless stream of strangely titled mixes with names like "Hyperpop," "Phonk," and "Lorem," which suggest uniform genres and scenes despite featuring seemingly random assortments of artists and songs. This article unpacks why Spotify organizes its music in this way and how, unintentionally, the process erases organic movements that developed outside of the app.

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.

'Shuffle Along,' a 1921 Broadway musical, brought jazz to American musical theater and helped pave the way for Black culture in the 20th century.

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.

Jazz provided a soundtrack for the Civil Rights Movement

Songs like Billie Holiday's "Strange Fruit," which portrayed the grim brutality of lynching, and John Coltrane's "Alabama," which was modeled on the rhythm of a speech by Martin Luther King Jr., were the backbeat of the movement.

Buddy Bolden assembled the first jazz ensemble

The New Orleans cornetist was a legend in the city, sometimes referred to as "king," for his electrifying performances, which captivated local dance halls by blending ragtime, blues, and gospel music.

Arthur Russell's avant-garde music spanned many genres

The classically trained cellist moved to San Francisco in the early 1970s, mingling with the hippie movement and the Beat Generation. After arriving in New York in 1973, he began exploring the nascent punk and disco scenes, infusing them with his classical training; however, his eclectic style might've been part of the reason he never broke through during his lifetime. That variety, though, is what draws so many devoted listeners to his work today.

The psychedelic playlist inspired by a Johns Hopkins experiment

Dating back to 1967, the playlist is over seven hours long and organized in such a manner as to echo users’ experiences as their trips rise, crest, and fall. According to the initial creator of the playlist, the music is a “nonverbal support system” that keeps users from prematurely returning to normal consciousness.

In the 1930s, New York banned buskers as part of an antinoise campaign
