B.1.5.EW:2 - Problem
A sequence answers “what happens after what?”. It can leave out “what is being done through what?”. While a person adjusts a step to a partner, they can already be performing a coordinated figure and the phrase containing it. They do not first finish adjusting and only later start dancing the figure.
The relation matters for action. A step that is correct in a solo exercise may be wrong in this partnered phrase. Improving the isolated movement can reinforce the failure if the needed change concerns coordination or the encompassing intention.
The reverse mistake is to call every concurrent or indispensable activity a constituent. Music reproduction can support a dance without being part of the dancer’s Work as that Work is bounded. A planning decision made yesterday can still constrain today’s action without being performed again now.
