Many non-dancers faced with either their own wedding, a friend's wedding or a ball decide that they would like to learn to waltz. It can't be that hard can it? Well I thought the same thing - started taking classes and 15 years later I'd still say my waltz is pretty average!
Learning to waltz is more than just the steps. Its all about the right posture, the position of the man and the woman, and rise and fall in the feet. That's why its almost impossible to learn from a book, or even a web page!
