This topic has been debated in detail on the salsa forums site. It became divided into 2 camps . The point of learning about a musical culture ?, it gives a very deep insight, into the foundational aspects of that which we currently call Salsa . By learning what went " before ", allows me to make my own interpretations , with a more informed template . Many discuss the lack of rhythmical expression in dance-- how can anyone teach something, that they know not ?. It comes back to the fundamental concept of researching your product . The background of all genres, are its roots . How can you plant a tree, that will grow, without roots ? The responsibility for educating the dance public, lies squarely at the teachers feet ( no pun ) . My concern when teaching my classes ? education-- musically and structurally . The choices need to be shown, if only for distinction , in music and styles . This is not unique to Salsa-- it holds true for all genres of dance-- if you do not understand ( the teachers ) how the dance is constructed musically, then how possibly, can you ever turn out anything, but robotic images of that which you personally present .
