A group of motion-picture engineers classified the following as the ten most dramatic sounds in the movies: a baby’s first cry; the blast of a siren; the thunder of breakers on rocks; the roar of a forest fire; a foghorn; the slow drip of water; the galloping of horses; the sound of a distant train whistle; the howl of a dog; the wedding march.

And one of these sounds causes more emotional response and upheaval than any other, has the power to being forth almost every human emotion: sadness, envy, regret, sorrow, tears, as well as supreme joy. It is the wedding march.
