[Spring 2017] I started to sketch a SOUNDmound as an entity. There is this thing called synaesthesia where humans experience one sense through another, like my mother saying “it smells cold today.” I thought about the colours of the musical keys from the twelve-tone equal temperament system which divides the octave into twelve parts. I arranged twelve musical keys as coloured circles. These I base on a personal feeling; there is no rule that says how humans should experience sound as colour. Each key-circle has a theoretical radius of 11 metres that I scale on to a two-dimensional archaeological map of Sandby borg. 11 metres is significant because this is the range that is used in the ‘Time Travel’ app (do-fi.se) which operates from geographical coordinates like those that can exist in the landscape at Sandby borg. I am sketching ways in which this app can provide the space for the SOUNDmound.
