This is a set of DVD that I bought in Shanghai. It features Leonard Bernstein when he was the musical director of the New York Philharmonic. He presented topics like "What does music mean?", "what is sonata form?", "What is Classical Music", "The sound of an orchestra", "What is a mode?", and many others. The NY Philharmonic would perform the pieces chosen by him and the concerts were both entertaining and educational. Although the DVDs cost around HKD1,000, I think it is a good investment, particularly if you want to introduce classical music to your children.
