Today’s Granoff Music Center Colloquium at Tufts University is “Blown Kisses: How Film Composers Ruin Romantic Tension” and features Tufts faculty member Frank Lehman. Whether for melodrama or comedy, few cinematic tropes are as memorable — or cringeworthy — as the rudely interrupted kiss. Composers for film and screen media have long appreciated the power of music to disrupt scenes of amorous passion, and have developed a wide arsenal of techniques and tricks to deflate romantic tension. This talk considers what happens when the job of film music is not to the mood, but to kill it.
