Which jazz styles emerged during the early 1900s?

During the early 1900s, several jazz styles emerged, primarily including New Orleans jazz, which featured collective improvisation and a blend of African American musical traditions. This was followed by Dixieland jazz, characterized by its upbeat tempo and instrumentation typically involving cornet, Clarinet, and Trombone. Other notable styles included ragtime, which emphasized syncopated rhythms, and early blues, which laid the groundwork for future jazz developments. These styles reflected the cultural melting pot of the time and set the stage for the evolution of jazz in subsequent decades.
