A commercial for Diesel's fragrance Fuel for Life has been playing all over the tubes, and it's unnerving me because of its use of the first bar of music from the second movement of Franz Schubert's Piano Trio in E Flat (opus 100). It's right at the end of the commercial (left). Bah bah bah bah-da-dah. Gets my attention immediately, even though it seems to be in a key other than E flat. You might recognize the cue from Stanley Kubrick's Barry Lyndon (right), in which the trio's beauty is A) in the correct key, and B) not reduced to a catchy soundbite.
