Assertion: Composition spans the senses.

Assertion: there are many similarities between the composition of aural space (i.e. music) and the composition of visual space.

If I knew more about cooking, my assertion might be stronger, but for now,

Suspicion: similarities also exist in composing not only visual and aural experience, but gustatory experience as well.

And of course, composition of tactile experience is something for which more and greater consideration is required and will be required the more we gravitate towards tactile user interfaces.

And! Let's not forget, Smell-O-Vision has actually been attempted. Poorly, yes, but it was considered. Misapplied, probably, but people are thinking.
