Hello,
Yes, Ice Dancing has evolved like all sports. However, some techniques have not changed. For example, pushing into the ice, leading with the knee very bent, pushing to the side and not
back, etc. remain as crucial elements to make one look like a dancer. Sorry the cha-cha is not in the book...it was not a USFS dance when the book was published.
I wrote the book to preserve the information of my coach, Jean Westwood the first world ice dance champion, and her coach Gladys Hogg both of whom produced many champions.
Compulsory ice dances are fading on the competitive scene so this information is important as young skaters will not be learning these compulsories and so who is to teach them in the future.
Sigh.
May you all enjoy ice dancing for many years. I am now 74, but still enjoy the occasional edge.
Sincerely, Lorna Dyer
