Each instrument is made up of 4 parts in order to create a loop. A stock is assigned to a particular portion of the instrument. As stock data is pulled in for a date, the price modifies the instrument part. If higher the value of the stock, the more notes are played for it's particular portion. The overall performance of the Dow Jones Index changes the speed of the playback.

For the video, three random stocks of the Dow Jones are represented by their relative position. Higher prices means a happier face, lower price means a sadder/scary face.

Overall, the sonification and visualization are pretty disorienting, which makes sense if you look at how the market has performed.
