An apparatus, method, and software product are used to sense a repetitive motion, such as walking, running, or tapping. Thus, a rate of the repetitive motion is determined. A piece of music is then selected in response to the determined rate, and the piece of music is played. This piece of music has a tempo selected to match or approximate the rate of the repetitive motion, so that the repetitive motion and the music are substantially in harmony. |
