Musical education has always been a topic my wife and I loved discussing when planning a family.
The first thing we agreed on was that we should do our best to expose our kid(s) to classical music. This is especially crucial in this day and age. That bar has been lowered drastically in the last decades and things aren't about to get better.
When I grew up, even there were no such records in my parents' collection, I was exposed to classical and orchestral music regularly, through movies and TV. Unfortunately, that's not so much the case in this day and age.
As for the rest, I can't imagine coming up with only ten names. The most important thing is to try and spark that curiosity which will make kids want to know more, that passion for music, whether it's Stravinsky, Coltrane, the Ramones or Tool.
