Anymouse, I agree with your comments.
I would like to add a few questions to this topic. My questions are no so much concerned with exactly how to do rise and fall, but for discussion purposes, what it the definition of rise and fall. When someone says "rise and fall" everyone thinks they know what this means, or at least have their own intrepretation of what this means. From looking at various discussions, I see several different definitions of rise and fall. Obviously if you are going to describe this action, you first have to know what action you are describing. I often see discussions of the differences between waltz and foxtrot rise and fall, only to find out that that the contributors are talking about different things because their definitions of rise and fall are different.
I will put this as a question rather than an opinion, because I am not sure my own definition of rise and fall is generally considered to be correct. I have heard the following:
1. Some experts say rise and fall is the bending and straightning of the legs, no mention of anything else. They assume the ankles bend because the knees bend but feel there is no need to describe this.
2. Some say rise and fall is bending and straightning of the legs and ankles.
3. Some say rise and fall is the bending and straightning of the legs, ankles, and body rise. The definition of body rise is also confused.
4. Some say it is the elevation of the top of the head. That of course assumes other actions to make this happen. That would make maximum rise occur at maximum height of the head, which can be different from the other definitions.
Does anyone know which of these are generally considered to be correct? Or is there a definition which one could say is generally correct? Can anyone contribute a better definition?
