摘要
Music has often changed, from a social point of view, and also the relationship between music and the city. This paper attempts to describe how music changes under the impact of Internet. The milieu of musicians and the audiences are concerned. The economic model of music has not burst into pieces, but it has deeply changed. There is a trend to pure consumerism thanks to internet （probably the sales of downloaded music will become more and more important）. Also, independent artists can use Internet and have a livelihood （fat tail phenomenon）. Therefore the diversity of music can be preserved. Concerts （music in the city） allow escaping from the losses of money because of piracy. There are several experiences for listeners, which are possible, some of them involving going to concerts and festivals.
