I am going to speak in ballroom and latin terms as those are the ones I am most familiar with obviously. No Posture is not easily described. "Stand up, don't slouch" is about as good as it gets. Some teachers talk of "tucking" the hips, I think that is ridiculously. Some talk about frame connection as originating in the sternum, some talk about the hips. Some students lean forward and need to be told to lean back. Some lean back and need to be told to lean forward. Some teachers talk of "stacking the blocks", last time I looked, my body is not very boxy.... How on earth do you describe on paper not to slouch when everyones slouch is different? Embrace, yes it is easy to tell when it is wrong, but how do you describe it perfect from the beginning? And as for ballroom and latin, there are descriptions for our Frame which would loosely equate to your Embrace, including dance positions closed, promenade, counter promenade, fallaway.... and the Latin books describes changes in the frame such as "man slides hand down ladies arm" But beyond that what else can be documented as strictly and as general as possible for everyone to agree on? Musicality... well we have time signatures for Silver + American and International Foxtrot. It is 28-30 measures a minute. Each step is ascribed a value, Slow = 2 beats. Quick = 1 beat. And = 1/2 beat. Pretty much every AT person I have spoken with scoffs at the idea of assigning ANY value of timing to a step, instead insisting on Feeling the Music. So there really isn't much to document for you... and what exactly IS the time signature of an AT? Floorcraft is not easily put on paper. Alignments are! And we do have an alignments column in the chart. I am very careful never to execute a natural turn facing Diagonal Center, unless I want to run into my fellow dancers coming down the line of dance. Alignments impart floorcraft is an easily documented fashion, but the words "don't run into other people" can't.
