Chromatic Automatic Pilot
Video & sound installation, 2015
Group exhibition, Base and (Super-)Structure
Basis School of Arts, Herzliya, Israel
Curator: Shlomit Breuer
Duration: 9:33 min loop
The project records a flight from Sde Dov airport in Tel Aviv to the landing at Rosh Pina airport in the north of Israel. Landscape data is scanned and converted into sounds using 72 sensors organised as a note system on a chromatic scale.
Throughout the video, 18 different four-note combinations are triggered and manipulated by the computer according to the grey scale variables captured by the preprogrammed sensors marked by crosses on a grid that create an image reminiscent of crosshairs. This produces sound combinations at different frequencies and volumes.

Sonic progression
The project is based on the sonification of varying greyscale values of the 72 pixels on the video matrix, represented graphically as a grid of crosses. In each of the selected 72 points (sub-matrices), I have defined sound production parameters: pitch, timbre and the range of change in tempo and volume, to be affected by the constantly changing luminosity of each pixel.
The sound evolution in this work is based on a harmonious progression of 18 different 4-note combinations with pitch intervals and circular recurrence known as the circle of fifths. This harmonious move appeals to the ear but eventually leads to a sonic tension that remains unresolved. Each point was activated only once during the video, and the note produced transformed according to the varying luminosity values of the pixel at that point. The specific notes selected derived from their location on the grid, considering the simultaneous visual movement on the video in a given interval.
Hence, two dynamic and inter-referential visual compositions were created: the changing video composition and the notes’ compositional distribution. At the same time, two sound compositions were created: one derived from musical considerations and the other from the varying visual occurrences on the video.
