Several scholars characterize the early 1900s development of blues music as a move from group performances to a more individualized style. They argue that the development of the blues is associated with the newly acquired freedom of the slaves. According to Lawrence Levine, "there was a direct relationship between the national ideological emphasis upon the individual, the popularity of Booker T. Washington's teachings, and the rise of the blues." Levine states that "psychologically, socially, and economically, Negroes were being acculturated in a way that would have been impossible during slavery, and it is hardly surprising that their secular music reflected this as much as their religious music did."
