My dh (musician) has always said he does not have much ( i say much, but he thinks he has some!) natural talent, but got there by hard work. He does not have perfect pitch. He is reading a book called Bounce - can't remember the author - which he is finding fascinating. It looks at the idea of natural talent or hard work. Author coming down firmly on side of hard work -10,000 hours practice before you are really good. I can see this with some sports and chess, but not sure about music, dance....
We have 4 dc. 1 & 3 do not seem to be particularly musical, but are both learning instruments. 2 has perfect pitch and appears to us to be naturally talented in music, but very lazy!
Dc4 (6) picked up a trumpet a few weeks ago and we were a bit wow! Now, dh is a trumpet player, so dc4 has obviously seen her dad playing, but she picked it up, put to her lips with a perfect embouchure. Dh said she's going to be good. She wants to practise all the time and seems naturally talented - perfect combination. He doesn't usually teach children until they have their adult front teeth, but has made an exception for her.
Fascinating debate. I would say I have a good ear, particularly when listening to trumpets!
As for children, surely they need exposure to music from the beginning - any music. If a child was brought up in a home where they never heard music and no-one ever sang with them - they wouldn't know how to be musical would they?
