Orts, Jose Antonio
A piece sensitive to the wind that the spectator creates as he or she walks by and to natural light. The hanging, black sheets capture the wind while the small aluminium tube above capture the ambient light reflected on the wall.
The work produces two harmonized musical notes (A major third) by means of two copper tubes tuned to F and A. The percussive sounds are emitted according to a long delay that begins when the spectator walks by and whose rhythm depends upon and is modified by variations in the natural light.
