Sophisticated mechanical technology and jazz evolved at the same time in history. By the early 1900s, machinery finally existed that allowed people to listen to recorded music at home. When people heard the first recordings in 1917 jazz immediately outsold all other forms of music. The rapid evolution of the art form was directly related to the fact that people finally had the equipment to listen to performances in their own homes. The rapid evolution of machines such as record players, radios, and tape players was due to the popularity of, and demand for, access to jazz. The success of one impacted the success of the others in the early years. These exhibits contain a variety of equipment dating from 1905 to the present. The museum has three playback machines invented prior to the first recorded jazz music. One is located at the end of the hallway on the second floor, a large music box. The walnut pump organ and the Edison wax cylinder recording machine are the others on the third floor.
