I got a chance to talk to sound designer Bill Milbrodt, who led the team that created musical instruments from parts of a Ford Focus. He talked about how his Car Music Project has constructed new instruments out of first an Accord (quintet) and now a 31-piece orchestra made from a Ford. Interestingly, some people doubted the sounds in the ad were coming from these instruments, but in a follow up Bill explained that, yes, they really are.
Most interesting, though, is the way in which the 22-person fabrication team had to find a balance between what was unique in the car and some of the timbres that come from conventional, classical instruments — and thus had to tackle the challenge of making everything sound right in tune!
