There needs to be a distinction made, between the way we count a specific rhythm for exam ,and or possibly class usage, as opposed to what many times, we change to suit a given circumstance .
To the beginner, this may all seem a little confusing.
But to re iterate a point made earlier-- the book is only , in some instances, a guide .
the beauty of the system is that it allows for many interpretations , and the whole purpose of dance in its finality, is personal expression .
So-- use what works best for you in the practical application.
