As a result of neuro-plasticity, the part of a deaf or hard of hearing person’s brain, which would respond to auditory information, starts to be utilised for other sensory information processed with the same emotional and structural depth as sound, cross-modal plasticity. To deaf people music is simply a haptic experience, evidently contrasting the broadly regarded definition of music as ‘organised sound’. If music isn’t definitively audio related, or tactile or relating to a singular sense, then can we make music with other sense as the medium? What does visual music look like? What does physical music feel like? What does temporal music sense like? If music is a pattern, where else can we apply its tenets?

If we expand the definition of music to "the intentional organisation of sensory phenomena over time to evoke emotion or aesthetic meaning," the possibilities open up dramatically.
What we are considering here is the intentional exploration of synesthetic-aesthetics. Visual music has been popularly explored and is an established historical art form.
