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 bring forth almost every human emotion: sadness, envy, regret, sorrow, tears, as well as supreme joy. It is the wedding march.
