Found the following on Usenet:
From _Adweek_, 18 January 1999:
"The soundtrack for the Jetta ad was composed by Pete DuCharme
of Somerville, Mass., who was given the assignment from [Arnold
Communications creative director Lance] Jensen, a longtime
acquaintance, after the spot had been filmed. DuCharme was specifically
asked to
write the music at 94 beats a minute--the cadence, it turns out, of a
brisk walk--so that the physical movement in the ads could be in
harmony with the chords. During the shoot, that beat was blared over
loudspeakers 'to keep everyone in sync,' [creative director Alan]
Pafenbach says. 'It's a wonder we weren't arrested.'"
