Progression of Music From the 1940's To the Present The progression of music from the 1940's to the present has seen extremes, it has been controversial at times, traditional at times and inspirational at times, but never have the American people turned away music in its entirety. There have been times when parents did not approve of the music that their children chose to listen to, but the parents had never turned away music. Music has been criticized and promoted. Since the 40's music has progressed from Ballads (which were still lingering around from the 30's) to blues (popular among Blacks)
