Musical by nature ... or is it by nurture?

In the long-running debate pitting nature against nurture, I come down firmly on the side that argues that our DNA is more influential in our personalities than how we were raised.

Except, of course, on those occasions when I believe the opposite.

For example, I like almost every form of music known to mankind, a fact that I attribute to growing up in my father's household, where music ranging from jazz to country was a constant presence. (Rock and roll had to grow on him. I vividly remember him saying after a Beatles song played on the radio that those guys were great songwriters, but they had to learn to sing).  If I walk into a house in which no music is playing, it feels odd to me, as if something crucial was missing, something that turns a structure into a home.
