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 !
