An interesting discovery in the study was that "a positive correlation was found between participants' musical training and their (resulting visual) acuity."
In other words, if you're tone deaf this won't help you.
The same principle applies to touch. Paul Bach-y-Rita started his career examining eyeballs and realized that a visual image drawn on a person's back could substitute for the sensations of the retina, in that a visualization of shapes would result. His most notable success was with a woman who had a condition in which she was unable to control her body unless she had a mirror in front of her. It was the only way she had to gain a sense of her body in space. By translating information from processors positioned at various points on her body to a patch on her tongue, Bach-y-Rita was able to reestablish her sense of her position in space, and by repeated use the associated neural pathways became well enough retrained to take up the task all by themselves. The commercial device resulting from this is aimed at restoring sight, rather than vestibular problems, and is called Brainport.
From their site:
BrainPort has demonstrated its ability to allow a blind person to see his surroundings in polygonal and pixel form. In this scenario, a camera picks up the image of the surrounding, the information is processed by a chip which converts it into impulses which are sent through an electrode array, via the tongue, to the person's brain. The human brain is able to interpret these impulses as visual signals and they are then redirected to the visual cortex, allowing the person to "see." This is similar in part to how a cochlear implant works, in that it transmits electrical stimuli to a receiving device in the body.  
As a final note on the subject, this video shows a blind man who has taught himself (and currently teaches others) to see using echolocation, i.e., bouncing clicks he makes with his tongue off of objects to orient himself, just like bats. (Want the answer to Nagel's "What's it like to be a bat?" Ask this guy.)
