Jazz was a factor for change and for regression. Jazz was the first music genre to be a form of self-expression. In this way, Jazz paved the way for more creativity as music can be based on the performer's emotion instead of something pre-determined by the composer. Simultaneously, this caused anger among old-fashioned people wanted to stop this new music genre completely due to it's association with speakeasies and the perceived notion that it encouraged rape. Jazz became a "cause" of sin and prevented the majority of Americans from wanting to do with anything similar to it, reducing musical creativity. Jazz music became a way to untie Caucasian Americans and African Americans as integrated and African American jazz groups gained popularity among both races. Although most Americans had negative feelings towards jazz in the 1920's, jazz in this era was a seed for growth in music and racial matters.
Jazz was a way for performers to express their emotions and for listeners of jazz to relax and enjoy themselves. In this art form, race became negligible due to the fact that some of the best musicians were African American. Even though jazz wasn't commonly accepted, African Americans and speakeasy-goers of all races were able to enjoy this music and allowed jazz to resurface in the near future (40's-60's). Overtime, jazz this became a factor in African American acceptance as well as a new music genre. Jazz music impacted musical creativity and became a bridge between African Americans and Caucasians.
