History of Jazz Music A Deep American Story
To get a grip on what jazz music is, you need to understand where it comes from. Jazz grew out of many musical traditions:
- African rhythmic complexity: Polyrhythms call-and-response communal music-making raw emotional expression the “blue notes” (flattened thirds and sevenths) of the blues music
- Ragtime: syncopated piano music (by Scott Joplin) that became popular in the 1890s.
- Gospel & Spiritual music: soulful faith-inspired vocal traditions
- European harmonic theory: progressions, formal structures
New Orleans was the perfect incubator. This port city had a unique cultural mix of African, Caribbean, French, Spanish and American influences, and it produced a musical environment that could be found nowhere else on the planet. Musicians like Buddy Bolden, Jelly Roll Morton and Louis Armstrong would carry this new sound to the world.
The U.S. Congress (Resolution 57, 1987) officially recognized Jazz music as “a rare and valuable national American treasure” That is often quoted in answer to that question: What is jazz music culturally?
Basic Qualities: What Are the “Jazz” of Jazz Music?
What is jazz music? This is a question people ask all the time and they want one answer. The truth is more complicated. Jazz isn’t a sound, but a collection of musical principles. It is defined by:
1. Being spontaneous
The soul of jazz. The musicians improvise melodies over a sequence of chords. You can play a jazz standard like “Autumn Leaves” in totally different ways every time.
2. The Swing and Syncopation Feel
Jazz has a certain rhythmic pulse, a “swing” or “groove,” in which certain beats are accented in unexpected ways. That is what gives jazz music its feeling of life and forward momentum.
3. Jazz Band
Jazz standard instrumentation is made up of the trumpet the sax, the trombone, the piano, the upright bass and the drums. Jazz music is really about how these instruments work. The rhythm section, which is the piano, the bass and the drums provides the foundation for the music. The soloists, like the trumpet and the sax and the trombone take turns playing their parts and exchanging phrases with each other.
4. Tonal expression and blue notes
Jazz musicians stretch and colour their notes in ways that do not exactly follow the western scale. These “blue notes” give them emotional depth and expressiveness.
5. Call & response
Call-and-response is a musical dialogue from African musical traditions and gospel music in which one instrument “calls” and another “responds.”

The Biggest Jazz Music Myths (Debunked)
A big part of understanding what jazz music is, is to get rid of the myths that keep new listeners away.
Myth #1 Jazz Is Just Background Music
The art of jazz is one of the most intellectually challenging in the world. You have to be able to think on your feet during complex chord changes, to do it in conversation with other musicians. It’s a chess-like mental process. Jazz is not wallpaper. It is a gift of deep listening.
Myth #2: “Jazz Is Outdated and Old”
Kamasi Washington, Robert Glasper, Esperanza Spalding, Snarky Puppy – these are some of the artists who are reinveting jazz music for the 21st century. Jazz is in flux, absorbing hip-hop, Afrobeat, electronica and world music.
Myth #3: “You Have To Know Music Theory To Like Jazz”
You don’t need a degree to get jazz. How does jazz music sound? It is joy, sorrow, tension, release, conversation—all things human beings feel instinctively. Start with some more accessible albums, such as Miles Davis’s Kind of Blue or Dave Brubeck’s Time Out.
Myth #4 Smooth Jazz is Jazz
This is controversial for purists. Improvisation is less important in smooth jazz than melody and playability. It is a derivative of jazz, but is generally considered by most jazz musicians and historians to be a separate commercial genre.
The Worldwide and Cultural Impact of Jazz Music
Jazz music is really a lot more than just the notes. The thing about Jazz is that it is the root of many other types of music, like rock and roll and r&b and soul and hip hop and pop music.

Jazz is the foundation of rock and roll and r&b and soul and hip hop and pop music.
Jazz was a way for the United States to reach out to countries during the Cold War. The United States government sent people like Louis Armstrong, Duke Ellington and Dizzy Gillespie to play Jazz music in countries. They wanted to show everyone how great American democracy’s
Jazz was able to bring people because it is a kind of music that everyone can understand. Jazz is like a language that can make people feel things no matter where they are, from. Jazz is the language of feeling it can cross any boundary and make people feel the same emotions.
But jazz has a lot of social significance too. It was created by black Americans in a time of intense racial oppression. The art itself was a statement of dignity, intelligence, creativity and freedom – values bigger than any nation or any era.
