Bartolomeo Cristofori coaxes just the right sounds from the musical instruments he makes. Some of his keyboards can play piano, light and soft; others make forte notes ring out, strong and loud, but Cristofori longs to create an instrument that can be played both soft and loud.

His talent has caught the attention of Prince Ferdinando de Medici, who wants his court to become the musical center of Italy. The prince brings Cristofori to the noisy city of Florence, where the goldsmiths' tiny hammers whisper tink, tink and the blacksmiths' big sledgehammers shout BANG, BANG! Could hammers be the key to the new instrument?

At last Cristofori gets his creation just right. It is called the pianoforte, for what it can do. All around the world, people young and old can play the most intricate music of their lives, thanks to Bartolomeo Cristofori's marvelous creation: the piano.
