This is not new. There is a coir-piece in which a number of coir singers sing
their own tune, all depending on the traiding of "their" stock on NYSE/NASDAC
(don't remember which if not both) in real-time. This is turing Sweden right
now. Now, that's realtime composing from "random" events!

Some singers can be quiet for quite some time, and then suddenly have much to
sing, where as others have a more steady stream of "notes" to sing. As I recall
it, the note they sing is for the price of the deal and the length is related
to the size of the deal. Many deals naturally results in many notes.

I don't remember how they did the detailed mapping, but I would consider using
a logarithmic function on the size of the deal to the length of the note. One
has to view the statistics of the stock to see what makes a good match to the
statistic of music (~1/f in energy).

To make this even more interesting, on a similar note (pun intended?), there is
a software program which mimics the shoutings that used to be on the London
Stock Exchange floor, since many traders where used to judge the trading "feel"
by just being on the floor. With the electronic trading they now got (many
years after more advanced stock-exchanges, like Stockholms SAX) people are
dispersed over town and lost this direct touch with the floor, so they created
a virtual floor instead.
