Over one hundred years old, jazz is constantly changing. Times change, tastes change, and as often as not jazz musicians have been at the forefront of exploration in the artistic trends of the twentieth century. Many jazz musicians dislike classification, and yet classification seems an unavoidable consequence of thinking about, talking about, even experiencing music. How can the various recognized styles or genres of jazz be identified? And what about the jazz styles rooted in the past--- are they still alive today, or have they become museum pieces "frozen in time"? Dr. Taylor discusses these questions, and demonstrates by playing examples at the piano.
