Thanks so much for posting this.
I enjoyed listening to KFH very much.
It seems the movement behind the well known names is happening. Great!!!!
I think the point he is making is that the horse needs to be taught to lift the head with the rider. Yes the horse would be perfectly balanced at liberty, but as soon as we add ourselves to the mix, the balance changes and there is a right way and wrong way for the horse to carry the rider which is influenced by the head and neck. I am currently working on exactly this with my horse. Bitless of course (which I was told could not be done) but he understands perfectly to lift his head just by me lifting the reins slightly. He needs constantly reminding though as he will travel with his neck and head long and low if left to be which is not good for him long term with my weight.
If you look at the old masters they had a hand position very different to what we see today where the hand was held much further forward and was lifted and dropped, not back and forth.
In the classical sense (traditional) it is a lifting of the bit in the corners of the mouth to raise the head, not a pulling/holding back. As soon as the horse responded to the lift the pressure was released.
