Well, I certainly have no musical talent myself, except to maybe write lyrics...my son however, is a different story.
When he was much younger, we were walking around in the electronic department of a Sams club store, and one of the batman movies was playing on the display t.v.'s. Next thing I knew, he walked up to a display keyboard, and just started playing/copying the theme song! Just like that! I couldn't believe my ears! Needless to say I bought him a keyboard for Christmas. He is able to play/copy anything he hears! Then a few years later I got him a guitar-which he likes to play even more than the piano, and can play any tune he hears, even if it's a song he has never heard before, if I just hum a tiny bit of something, he can play it. He can also sing anything and has a wonderful voice. I believe it is a God given talent-because he sure didn't get it from me!
