The Dow Piano

Here is an interesting way to start your year: CNN created the “Dow Piano” — translating market action into notes, and trading volume into sound volume.

The result is a series of five-note scales spanning three octaves (notes are determined by closes).

“Heavy trading volume – most notably on the day of the May 6 ‘Flash Crash’ – leads to high musical volume. Notice the piano tends to play quietly around holidays. The notes are generally clustered in series of five, representing Mondays through Fridays.”
