“You have to know that there are some who quickly, when they have learned a little and yet having little practice of it, place themselves to teach others. They teach without foundation nor rules that are true, nor understand that the knowledge is very different from teaching and that this way of teaching is acquired with length of time. For as the misura and the tempo require great time in order to know them, one who does not know the misura nor tempo and does not have methods of teaching can be called an imperfect giocatore, and one must be warned of learning from them.”
