I am going to borrow a piece of terminology from fencing. What most people call a step, a sequence of steps, I am going to call a phrase.
A phrase is an extended attack parry-riposte parry-riposte that continues until a touch is landed or until they break distance. A protracted phrase was seen to be the hight of achievement by classical fencers.
All of this talk makes me want to get my fencing gear out again, not my tango shoes.
I like that. “Phrase” is better than “figure”. And, it fits better if you are using “vocabulary” as the word to describe the multitude of fundamentals. Vocabulary – phrase – sentence?
I like phrase as opposed to figure because figure implies indivisible completeness whereas phase is, as you pointed out, composed of vocabulary.
For the next level I would probably switch sports to rugby (Limerick being the undisputed home of Irish rugby) and use passage, as in passage of play.
