I really would love to learn the piano. I hear you play, can you tell me about it?
Yes! It's an acoustic string musical instrument. 
Really? It sounds very beautiful! What a great invention!
It really is a beautiful invention!  Bartolomeo Cristofori invented it around 1700! 
Wow, it must have been a gift from God to create such an amazing instrument.
I agree. When it was first invented the strings were struck by hammers. 
Yeah they did not have technology back then. They had to use what they had.
It's amazing how far we have come since then.
Yes totally, the piano is my favorite instrument. That is why I want to learn all about it.
Well piano is short for pianoforte.
