If you can find your way to the European IDSF Championships from Madrid. You will se that the V.Waltz Natural Turn is being danced flatter than it was a little while ago. The Reverse, if we can imagine the head is touching a ceiling is stays there. No rise or fall. If you do the same to the Natural Turn you will see that the rise and fall is to a minimum, The progression is along and not with that pronounced rise we were once taught.
