Sound is, at times even more than the image, an insidious means of affective and semantic manipulation whether it acts on us physiologically (for example the breathing noises) or, through an added value, interprets the sense of image and let us see in it what in the absence of sound we would not see or see differently. The typically rhythmic nature of visual language has established relationships of affinity and contiguity with music (understood in the ethnomusicological sense of the term according to which "music" is any form of organized sound): the image contains the possibility of being filled from the sound without losing its purely visual-dynamic image characteristics. In general, sound and image reach a total integration of elements, so much so that they are no longer able to distinguish them in their autonomous essence.
