"As man, the chasse roll commences RF back backing DC, and ends with a LF open toe pivot to end backing LOD, having turned a total of 7/8 to the left. Timing is 1&23.
It is nothing like a quickstep tipple chasse to the left."

It maybe be nothing like the quickstep figure, but this sounds very much like a waltz action often identified with the word tipple.

Basically, a tumble turn, with a chasse closure replacing the feather-like passing action of the original.

A tumble turn could be substituted, but some might find this tipple or chasse action more waltz-like, and the tumble more foxtrot-like. Just make sure both partners do the same version!!!

A good lead follow exercise is to pick one of {tipple, tumble, side lock} whithout saying which it will bit - it will bring out a mutual understanding of their differences.

"Basically, a tumble turn, with a chasse closure replacing the feather-like passing action of the original."

Correct!

"It maybe be nothing like the quickstep figure, but this sounds very much like a waltz action often identified with the word tipple."

I have also heard the term "ripple" used, and I know some who teach a tumble turn as a chasse to the right with a locking action for the lady, much more akin to a turning lock.

Unfortunately many of the figures that are not in the Alex Moore/Guy Howard books can appear in different areas with different, sometimes confusing, names. I suspect that is what motivated Geoffrey Hearn to consolidate the thoughts behind the letter service into his book.

We are no wiser now than at the beginning. I doubt if it was anything too complicated. Maybe it is going under different names. Could it be just simply Side Locks, or as Geoffrey Hearn calls them, a Double Side Cross.

Why do you think we are no wiser Quickstep?

The figure is a Chasse Roll to Left as described by Geoffrey Hearn. He describes it as 1-3 of a developed Progressive Chasse into an open Toe Pivot. He describes the tumble turn as a feather finish into an open Toe Pivot, which is why I agreed with the comparison made by Anonymous.

The man will follow with RF back down LOD. For a double side cross the man would follow LF fwd down LOD.

Heres a copy from The Ballroom Competition Figures 2.
Waltz.Back LF. Lady outside backing LOD. Then turn 3/8 of a turn to right, RF to the side to Chasse RLR to end facing (diag to centre) as the weight is taken on RF on step 10 continue to Pivot 1/2 to right and lower to end backing diag to wall on new LOD.
Same in the Foxtrot except that the lady is not out side on step one. And facing DC becomes DW.
I'll still stick to the Side Crosses

"Heres a copy from The Ballroom Competition Figures 2."

A copy of what?
That is clearly not a chasse to the left of any kind, and will not fit into the routine originally described.
I have seen that described as a tumble turn and wondered where it came from so thanks for the reference.
It is however totally different from the (foxtrot) tumble turn described in Geoffrey Hearn's book and demonstrated by the Hilton's on a tape of which I cannot recall the title at the moment.

As I mentioned in an earliier post it can be very confusing if there are two very different figures named "tumble turn". Maybe we should add natural and reverse to distinguish them.

The confusion come from quickstep having inserted a spurious outside partner step on the lady's left, man's right before the actual figure.

sorry, man's left, lady's right outside partner.

The actual figure begins with the man's step back on his right foot, lady's on her left.

I' ve got the Hilton' s doing a Chasse Roll in the Waltz and the Foxtrot. Waltz was the question.
The group is. Open Telemark. Curved Feather from Promenade. Chasse Roll to right. Natural Pivots. Natural Twist Turn to Lunge. heel pivot.
Commence diagnal to the centre. Chasse Roll to right at corner.
We have a Tumble Turn in the Foxtrot and Quickstep. Nothing in the Waltz. We also have a Rolling Chasse in the Waltz. Take a pick.
Anonymous.Enough of you using the words spurious remark. You just cant help it can you. The script which you have apparently have not got says
Chasse Roll to the right at a corner. MAN. LF back with lady outside backing LOD ( its the man backing LOD )
The Lady. RF forward outside partner facing LOD.
Try keeping your illegitimate remarks to yourself and stick to the subject at hand.

More like enough of your GROSS INCOMPETENENCE.

You confused everyone else by describing a sequence beginning with a spurious outside partner step, that is NOT A PART OF THE ROLLING CHASSE OR THE TUMBLE TURN. Instead, it is an artifact of whatever steps preceded the figure in question.

You will never ammount to anything as a dance educator until you can move beyond rehashing out of context trivia, and learn to actually EXPLAIN WHAT IS RELEVANT TO THE QUESTION AT HAND, without confusing them with random out of context babble.

A tumble turn or a rolling chasse starts with the backwards step of the man's right foot, lady on her left foot INLINE. Basically, just as a feather finish would commence.
