I always wanted to play piano but my mother didn't want a piano in the house.
That's so sad! I have always loved piano music. Do you have a favorite composer? 
I love all classical music.  Bartolomeo Cristofori invented the piano in about 1700
Oh that's awesome! I can't believe the piano has been around that long! How did he create it?
Bartolomeo is a bit of a mystery.  Nothing is known of Cristofori's early life.
Oh! Very mysterious! Do you know of any of his compositions? 
I don't know of any compositions, but rumor is he served as an apprentice to the violin maker Nicolo Amati
