This track was made using a combination of visual synthesis and process composition.
I took the map of Bern and cut-away everything but the river itself. Then I used dRAW optical synthesiser, by @riccardomarogna, to create an instrument that âplaysâ the sound of the riverâs course. The sound evolves as the synthesiser LFO scans along sections of the river to use as its sound source.
The melody of the track is procedural with A (for Aare) as zero. Each subsequent note is calculated using numbers from the coordinates of the riverâs source (Unteraar Glacier) and mouth (below Koblenz) as intervals. Therefore we have two distinct melodies, one for the source, and one for the mouth. I used probability features within Ableton to create constant movement between âsourceâ and âmouthâ melodies, like the flow of the water.
The rhythm of the track is similarity procedural, with the spacing of the kick / bass drum calculated from 0:00 using intervals from source and mouth coordinates to calculate beats from origin. The rhythm also uses randomised automation to flow between the source and mouth.
The aesthetic is overwhelmingly dark, despite the classic picture of the Aare as a scenic visitor attraction. This just happened, but made me also consider the icy black water at night or the experience of those 20-30 people who will drown in it each year.
