There is a strict relationship between places and sounds. Not only because sound waves are deflected and deformed by things, not only because the earth's curvature extends the strings differently and the temperature alters the sound and skins of the drums, but also because in each place the dance, the rhythm, the love , poetry takes different forms. There are music from the north, south, west, music from the metropolis, music from the countryside and from the villages... Instruments, temperatures, rhythms have always been mixed together, forming sound networks that connect worlds.
