I been dancing a lot (14 days and counting). So a lot of followers. Also dropped in at some partner work workshops out of curiosity. And I been thinking about my experience with most followers I danced.
I will exclude those followers who are reasonable good at following. They make up may be 10% of those available. Let me focus on about 60% or so, all appeared to have been dancing for at least 3-4 years or more. A few among those 60% had good body movement or isolations that they could correctly apply to the music. But almost all of them exhibited one of the following which caused hinderance in connection and not so enjoyable dances:
1. Arms: either too stiff, or wrong tension, changing hand hold incorrectly (I lead lightly with one or two fingers only), missing offered palm, hand (often by anticipating what I might do or simply not paying attention to where my palm is).
2. Steps: absolutely wrong foot position and stepping coming out of CBL, wobbly turns, turning out of sync with the music.
3. Frame: stiff, incorrect or contrived body movement that interfers with lead when picking them up.
4. Responsiveness to lead: late by a beat or two, need leader to move them.
Most of above are fundamentals that you shouldn't really have to expect from intermediate level followers yet they persist.
My thinking is once followers transition from advance beginners low/early intermediate stage, their learning curve is steeper. The guys once they reach intermediate level have easier learning curve in incorporating and integrating body movement, shines, etc in their dancing. For the followers the curve is just starting.
I know one follower from Paris for past 3 years. She probably been dancing for ten years and was attending the Yamulee partner work class. I was surprised how pack the Yamulee partner work class gets. More surprising was number of followers in that class. I asked her why as a follower she expected to learning anything in that class since if a good leader leads combinations of those multiple spins and moves Yamulee was teaching, any decent follower would be able to follow. She said she can learn about connection, etc and get better. Yamulee wasn't teaching any of those at the workshop and their patterns are famously better for choreography than social dancing.
