On a happy note, let's talk about resources for teaching music. I am musically challenged so I am always thinking of new ways to help expand my kid's musical horizons.
Zeekok publishing has a wonderful Music Appreciation Program. It introduces children to seven different composers and includes biographies, a teacher's manual and music CDs. It can be bought individually or as a set. We are using it with some of our children next year. Here are some more thorough reviews if you want more information.
Classics for Kids is a wonderful web site for teaching kids about classical music. The web site features music, videos, lesson plans, and newsletters you can sign up for. It is a wealth of information.
I also love the Piano Guys. They put together music videos with classical music while playing in interesting locations. The song Frozen with Vivaldi is below.
Some places to get you started.
