The type of music taught must be socially acceptable and still reflect what the children already know with a heaping pile of stuff they don't. Teaching kids music is great when they are young, but as they grow older their academic tastes mature and they develop distinct likes and dislikes. At a certain point some children will not want to learn any more music while others will. This brings us to a turning point in their education. Although, music a funny thing because it is nearly impossible to find someone who doesn't like music.
Many people have their type of music and in schools there is a wide variety of musical tastes.
At some level music reaches everyone. Most schools involve the classics with their music curriculum and many also have jazz. I believe that there is too much of an emphasis on the classics. I know that they are a huge part of music, but music grows and expands. I have not heard of a music class where the music of our growing culture has been regularly used.
