Small Beeswaxes
Recent American Express Blue commerical (or some "blue" credit card geared towards small businesses by holding off debts until they're larger than the average debt maximum for regular people):
Commercial starts out in greyscale, maybe a hint of manilla (a la sepia). Musicians in a band arguing about where to start from after a mistake in the playage. Mathematical terms (sorry, numbers) get thrown around. The ever omnipresent Narrator comes in. "Music means you learn math. Use the American Express Blue card and money goes towards musical education within schools".
As a self-appointed, poor musician, I can assure you that music does not require much math. It requires counting. As far as I know, preschoolers elementary schoolers pre-freshmen high schoolers collegiate adolescents and adults know how to count.
