Abstract
In accordance with a traveling state of a vehicle, a tone indicating, for example, that the vehicle is traveling is generated as a tone of a first performance part. Also, a variation in any of various states of the vehicle, such as an operating condition of a winker or flasher, is detected, and a tone corresponding to the detected state is generated as a tone of a second performance part. For example, ensemble data including the first and second performance parts may be employed.
