Good morning,
I did sleep well, however I must have been dance-dreaming, as I woke up with some ideas about my own problem.
After one measure of basic A, steps continue and compare as follows:
1 2 3 4 5 6 7
A: Lclose Rfwd Ltap Lstep Rtap Rback Lclose
B: Rback Lclose Rfwd Ltap Lstep Rtap Rback
C: Lrock Rstep Ltap Lstep Rtap Rstep Lrock
C is another 6-count version of Boogie-Woogie (again started 2 measures later - I prefer to start on the rock step, as I am used to do in jive).
Compared to C I find A more logic than B; the rock step has been replaced by a close forward, which allows better forward movement.
However, basic A starts actually one measure earlier, on the "tap step tap"-part, which I believe is the part where turns are made and completed (resting part).
I would prefer to start on the preparatory part (the equivalent of the rock step), this would be for basic A on a closing step. Then again I am not so sure about starting on a closing step. This may explain why basic B starts with a back step before closing.
But what about starting on count 5 of basic A: with a tap, bouncing back ? Disadvantage may be that then you loose your final "resting" point at the end of the figure, which is this starting tap.
I think the question of which part of the basic to start on is interesting when learning/teaching figures. Once you are dancing an amalgamation of figures it does not matter any more.
Still I wonder what this shift of one count means for the rhythmical interpretation of the music. Maybe I will find out by dancing both versions.
On counts 3 and 5 (which I believe are the strong beats in the music) there are taps in basic A and steps in basic B. I am inclined to say that steps, on which also the turns are made, are preferable on strong beats. But I am not a specialist.
Isn't it strange that two basics, which vary only in starting with one count difference, would be both correct ? Where is the accent in Boogie Woogie dancing ? Do both basics have their own rhythmical interpretation ?
Questions, questions, questions...
