Jazz was born in the early 20th century in New Orleans, a bustling commercial center located at the mouth of the Mississippi River on the Gulf of Mexico, at the confluence of extremely diverse cultures such as French, Spanish, Caribbean, Anglo-Saxon, and German, which fused with the African traditions of creoles and recently emancipated slaves. In those times, it was customary for parades and funeral processions to be accompanied by brass bands. On the way to the cemetery, the musicians played funeral music, but on the way back they adopted a unique swing rhythm that over time became an important element in jazz. Later, bands began to play at dance events, becoming a true fashion of the times. Jazz could frequently be heard in dance halls, gambling dens, and brothels in the red-light districts, known as Storyville, where jazz was born and developed in New Orleans. The New Orleans jazz style was established by cornetist Charles “Buddy” Bolden (1868-1931) and his ragtime band. Collective improvisation, a kind of jazz polyphony, is a central element of this style of jazz. New Orleans jazz was created by African Americans, who were always at the forefront of all jazz innovations. Ferdinand “Jelly Roll” Morton (1890-1941), the first jazz pianist and composer, Joseph Oliver (1885-1938), known as the “King of Jazz,” and the great Louis Armstrong were all products of New Orleans jazz.

Jazz is a music genre in which improvisation is usually an important part. In most jazz concerts, players perform solos that they invent on the spot, which requires considerable skill. There is an extraordinary variety in jazz, but most jazz pieces are highly rhythmic, contain a sense of anticipation through repetition, called “swing,” and use “bent” or “blue” notes. Jazz often features call-and-response patterns, in which one instrument, voice, or part of the band responds to another instrument, voice, or part of the band. Jazz can express many different emotions, from pain to pure joy. Jazz can be the sound of freedom – as the music was a powerful voice for people who suffered unjust treatment because of their skin color or because they lived in a country ruled by a cruel dictator.

Jazz musicians place great value on finding their own sound and style, which means, for example, that trumpeter Miles Davis sounds very different from trumpeter Louis Armstrong. Jazz musicians like to play their melodies in their own distinct styles, so there are many recordings of the same song, but each will sound different. The musicians’ individual playing styles make each version unique, as do the improvised solos. Jazz is about transforming the predictable into something new and turning the familiar into something surprising. These are just a few reasons why jazz is an extraordinary art form and is considered “America’s classical music” (National Museum of American History).

Man, if you have to ask what jazz is, you’ll never know. Louis Armstrong
