I am often asked which is the most important for west coast swing or dancing in general.. is it technique, musicality, showmanship, timing or many other related possibilities ? my reply is wow !! that's a loaded question !
Mainly because all the other elements I was asked to compare technique to which are musicality, showmanship and timing..are all comprised of specific techniques of their own which make them useful..
So for me I strongly believe that technique has to be the obvious answer to the question !
The shortest and most precise answer regarding wcs or dancing in general.... is that.... HOW you do anything is more important in most cases than WHAT you do. Even the most flashy tricks and moves simply do not have the same impact if they are excecuted poorly. Enough said !
