What Is Jazz?
Jazz is a musical genre that originated in the African American communities of New Orleans, Louisiana, in the late 19th and early 20th centuries. It is characterized by swing rhythms, improvisation, complex harmonies, and a unique interplay between musicians that makes every performance a live conversation. Jazz is widely considered one of the United States' most significant and enduring cultural contributions to the world.
The Origins of Jazz
Jazz grew from a rich stew of musical traditions: African rhythmic traditions, blues, ragtime, gospel, and the brass band music common in New Orleans at the turn of the century. The city's unique cultural makeup — blending African, Caribbean, French, and Spanish influences — created the perfect incubator for an entirely new kind of music.
By the 1920s, often called the Jazz Age, the genre had spread to Chicago, New York, and beyond. The invention of the phonograph allowed jazz to reach audiences across the country and, eventually, the world.
Defining Characteristics of Jazz
- Improvisation: Musicians spontaneously create and elaborate melodies in real time.
- Swing feel: A rhythmic quality that makes the music feel like it's moving forward with momentum.
- Call and response: Musical "conversations" between instruments.
- Blue notes: Slightly flattened pitches that give jazz its emotional expressiveness.
- Complex harmony: Use of extended chords (sevenths, ninths, elevenths) beyond basic major/minor.
