Did you know it's been scientifically proven that jazz music enhances the listener's creativity? That by listening to jazz you can have more "Eureka Moments" than if you hadn't been listening? Or how about the fact that children who receive jazz instruction score higher on test scores than those who do not?
Listening to jazz, chock full of improvisation, can enhance creativity as you work on most any project.
During "theta" flow states, people can experience sudden intuitions providing ready-made insights and new solutions to unresolved problems (Eureka moments).
