Of course it isn't a joke! I'm not saying that every school in the country has a brilliant standard of music education. You have obviously experienced a very bad approach which no one could or should defend. However, you should not allow that to detract from the excellent work that is done in many schools across the country. I think music education is good or outstanding in many schools. It is taught by a committed workforce despite many difficulties. It could be a lot worse. The model of music education outlined in our current National Curriculum is worth defending.
