1. First of all children need to know that there are many kinds of music such as classical music, rock music, country music etc. We need to expand our horizons.
2. I think that during musical classes children should learn how to sing and also how to play. Because they should know the world of music from several sides.
3. Also I reckon that we need to tell children about composers, singers. That can give the idea of what music is and how difficult it can be to be come a really great man in this area of life.
