"What would be truly surprising would be to find that sound could not suggest colour, that colours could not evoke the idea of a melody, and that sound and colour were unsuitable for the translation of ideas, seeing that things have always found their expression through a system of reciprocal analogy."
To some degree, all experience is synesthetic because the 'synesthetic experience'is the result of 'the united senses of the mind'.
The human sensorium; touch, taste, smell, sight and hearing have synesthetic qualities in their interactive connections. We see the 'synesthetic experience' particularly in all forms of art —in poetry, painting, sculpture and music. The 'synesthetic experience' serves as a means to unify the arts through a psychological unity of the senses. Synesthesia refers to the transfer of qualities from one sensory domain to another, to the translation of texture to tone or of tone to colour, smell or taste. Because the various modes of art rest on and appeal to different senses, synesthesia correspondences among the senses and synesthesia can point to similarities and analogues, as well as to metaphors or differences among the artistic forms.
