Deleuze on Counterpoint

Different ways make use of the available interrelations of things and their complexities:

“Not only does birdsong have its own relationships of counterpoint but it can find these relationships in the song of other species, and it may even imitate these other songs as if it were a question of occupying a maximum of frequencies. The spider’s web contains ‘very subtle portrait of the fly,’ which serves as its counterpoint. On the death of a mollusk, the shell that serves as its house becomes the counterpoint of the hermit crab that turns it into its own habitat, thanks to its tail, which is not for swimming but is prehensile, enabling it to capture the empty shell. The tick is organically constructed in such a way that it finds its counterpoint in any mammal whatever that passes below its branch, as oak leaves arranged in the form of tiles find their counterpoint in the raindrops that stream over them. This is not a teleological conception but a melodic one in which we no longer know what is art and what is nature (‘natural technique’). There is counterpoint whenever a melody arises as a ‘motif’ within another melody, as in the marriage of bumblebee and snapdragon. These relationships of counterpoint join planes together, form compounds of sensations and blocs, and determine becomings.”
