Abstract
In a music reproduction apparatus designed for a listener to enjoy music while experiencing variations in vehicle status, plural types of phrases, which differ from each other, are assigned to plural tracks and are reproduced in accordance with reproduction parameters, which are controlled in response to vehicle status information. It is possible to control the setup values of reproduction parameters suiting vehicle statuses in response to travel environments. In addition, it is possible to synchronize the reproduction start timing of a music reproduction unit corresponding to one measure being reproduced by a first track with the reproduction start timing of a music reproduction unit corresponding to plural measures being reproduced by a second track. In a music information distribution system, a server stores music files including reproduction parameters suiting vehicle statuses and travel environments, so that the music reproduction apparatus reads them so as to reproduce corresponding musical tunes.
