Figure 8 present in ritual. Recent studies have also demonstrated that many rock art sites around the world are indeed located in places with special acoustics. In short, the literature pertaining to the new field of archaeoacoustics strongly suggests that rock art landscapes were not perceived as “dead silent” by their creators. What about ancient Californian soundscapes? Is there any possibility that rock art and ideas on sound and/or music were related in this specific region? This paper is the result of a research that is being undertaken in the Artsoundscapes ERC project and it aims to provide new perspectives on the understanding of the Californian past through a multidisciplinary perspective. The study of sources from missionaries and more recent ethnographers will allow us to inquire into the place given to sound and/or music in ancient Californian societies, especially in a ceremonial context. Also, we will establish a list of pre-Hispanic musical instruments from sources such as chronicles and archaeological reports and collections. Finally, we will reflect on the similarities and differences in the field of ancient soundscape studies between both California whose border is a recent invention in spite of their prehistoric cultural similarities.
