” A vast amount of information in the shape of index graphs is constantly being created at the different stock markets of the world. In the project “NASDAQ vocal index” the graphs of companies listed on the NASDAQ are transformed into music. Computer software converts the graphs to sheets of music, and the scores are presented online on a projection screen, to be read and sung by a member of a local choir. Every company has got its own voice and together the choir vocally interprets the current situation on the market.” [via] – Link & video.
