4) Be an active listener, and identify instruments, voice types, etc.
First of all it's a great idea to listen to music that does this for you. My kids love Peter and the Wolf by Prokofiev. I'll be posting a review of my two favorites, with a third potential favorite on the way. Here is one of them:
You will be surprised how quickly even your youngest children can identify instruments not just in Peter and the Wolf, but in other pieces as well.
5) "Dig In"
Learn as much as you can about certain performers and composers. The more you learn about them the more you are going to be aching to hear them. Knowing little anecdotes and stories are great for sharing with kids.
6) "Take Music Lessons"
Learning an instrument or how to sing will give you a deeper appreciation for what the pros do. And who knows, maybe you'll find a secret talent you never had. Also, enrolling your children in lessons early can get them into it when it's still "cool". Then it might stay "cool".
Whatever you do, stick with it. The world of classical music is such a rewarding one to live in. Support the arts in your communities, and listen as much as you can--but do it actively! Don't just let this music become background music, or we may lose it forever.
Happy listening, and good luck!
