The most famous mainstream work which highlighted synesthesia-like experiences in a non-synesthete audience. Fantasia went on to become the 22nd highest-grossing film of all time in the U.S when adjusted for inflation.
"To most of us music suggests definite mental images of form and colour. The picture you are about to see is a novel scientific experiment - its object is to convey these mental images in visual form…"
The most illustrative film I have found thus far on synaesthetic design principles. A near alchemical fusion of colour and music.
To produce the film’s musical soundtrack, McLaren photographed rectangular cards and arranged these shapes in sequences on the analog optical sound track to produce notes and chords. He then reproduced the sequence of shapes, colourized, in the image portion of the film, so that audiences see the shapes they are hearing, as sound.
“Mankind has until now always tried to satisfy its need for the highest spiritual exaltation only in music. Only tones have been able to… transport us to the highest realms… Yet colour is just as capable as music of providing us with the highest ecstasies and delights”
“It is necessary to regenerate painting, after so many centuries of devotion to religion, to dominating agents, to the stupid bourgeoisie. The public need to add to the action of the optic nerve those of the olfactory, acoustic, and sensory ones. I am still groping in the dark, but I believe I can find something between sight and hearing and I can produce a fugue in colours, as Bach has done in music. At any rate, I will no longer be content with slavish copy.”
