In the streets and canals of Venice, Gabriella can hear nothing but sweet music. The drying laundry goes "slap-slap, " the church bells go "ting-aling-ling, " and the lire go jing-aling-ling. Soon, Gabriella is humming her way through town -- and everyone hears her song Some find it sad, others smile when they hear it -- but none can forget the beautiful melody. Before long, a certain struggling composer is inspired by Gabriella's song -- and a beautiful symphony is born.
