basic talent..??

3 weeks ago, I saw someone playing the piano clearly.I asked every people that is near with me, "How can he/she play it well??". Then most of them answered, "it's his or her talent".

from the example above, I make a conclusion that for playing the music instrument well, we need a talent.But if no one invent those music instrument, we couldn't know that there were much talent in playing those music instrument..

So, everyone who read this blog, please answer my question. "How many pure talent are there in the world and what are them??"
