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.

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.
