Dacing a whisk in the waltz I find it hard not to rise on the second step(RF), I drift onto that foot and use the knee to soften the movement but this usualy results in a little to much rise,it happens else where and sometimes produces a pop. It is difficult to control. Any ideas to solve this problem.

Hi DAve
The first step in the whisk (LF forward) certainly has a lowering, and the second step brings you back 'up' to where you started.
What makes you think you're rising too much? If you're keeping your knees soft and aren't doing a big foot rise, you should be ok.
A 'pop' as you also describe sounds like rising too quickly (i know from much experience!!) rather than too much, and is relatively easy to cure

Phil. That is my problem,pushing up from the ball of foot(RF) wnen softening the knee . An old habit which seems natural to do . It feels good and I wonder why?

It has to do with the waltz rise on three and the drift.

Dave.If you have a technique book you should look at it. Rise and Fall.
Commence to rise at the end of 1; continue to rise on 2 ; up on 3. Lower at the end of 3. If you haven't got a book, your trying to navigate without a map. One more thing. I was taught that a Whisk is just a Change Step with a cross behind. not allowing my weight to move any further than it is on step 2. Then Cross behind staying square, and lower. The lady is the one that opens into Promemade

"I was taught that a Whisk is just a Change Step with a cross behind. not allowing my weight to move any further than it is on step 2."

While it may feel close to this, this is insufficient. If you did not let your weight move further back, it would never reach the heel of the foot that crossed behind and you would not be able to take a proper drive, moving your weight forward again through the length of that foot as you prepare the step after the whisk. But is is important that you not allow your weight to drift too far back.
Whatever you do, do not actively cross your legs, ever, in any of the swing dances. The leg cross happens because the body moves across the standing leg in a way that brings the moving leg into a crossed position. As another check, if you actively cross the leg you will probably also get turn out and do a latin cross rather than a ballroom one.

"The lady is the one that opens into Promemade"

There are several possible alignments for the basic whisk, and who opens to promenade depends on which one you choose.

"The first step in the whisk (LF forward) certainly has a lowering, and the second step brings you back 'up' to where you started."

This is absolutely completely 100% WRONG.

There is no lowering in step 1 of any figure in any ballroom dance.

Thanks everyone. I have solved the problem. I was reaching on the second step (RF). Not taking the time to allow my body to place the foot . Gleave once said " Have the currage to dance slowly" That was the problem?
