Regarding how to begin with the ice dancing pattern, I can well relate to what
@Susan1 tells us about her first lessons. In our club, we have good ice dancing coaches, and ardent ice dancers of almost all levels. Last winter season, I went to a class for beginners and intermediate dancers. There were only adults, some well in their sixties, who have been practising the dances for ages. Our coach did some basics first (always a must and I focus very much on that as I also need it for my free style skating), and asked us what dances we'd like to pracitse. Every lesson I was busy running after one of the other ladies who were doing their steps in rhythm and secure enough to be good models. My, it was tough! I was told to watch, focus, copy, copy, copy...and get into rhythm.
In our class, we had a very good skater, who has passed some tests and is far advanced. He can do all the dances on his own, and sometimes does them with his wife. She knows the dances, too, but she's rather insecure and wouldn't go fast, and her patterns cover only half of the rink when she goes on her own. When the two of them dance together, logically, he has to take care of her and adjust to her pace and length of steps. They are lovely to watch btw.
In spring, I took another class and I was lucky to have a mate who would partner me for some exercises. We only did some edges, chassees and easy steps together - it was exciting, yet not easy to stay in tune together, hold a good posture and simultaneously pay attention to the partner. I wouldn't be able to do a single step in hold if I wasn't able to do it on my own.
