Hi Matthew,

Sonification is the use of non-speech sounds to provide information about the underlying data.
When you get an error dialog on your computer, a particular sound accompanies it. That is one form of sonification.
In dealing with a large amount of data, it is necessary to understand the predominant emerging pattern. Sighted scientists and folks in general do this by drawing graphs based on the data and examine the shapes by the use of there sight.
Sonification has the promises to do the same for the blind (although sonification is used by everyone, not just the blind).
In this particular case, you just map the useful characteristics of the data to particular sound attributes and attempt to make sense of the resulting music.
For example the increase in the data values is mapped to the increase in the pitch. So when you encounter higher values, the pitch of the sound is also higher and vice versa.

You can find a tonne of information by googling sonification.

Regards
Roopakshi
