Its also worth noting, that most salsa " teachers ?" have little or no formal dance training.
Not having formal training is one loss, rejecting additional training is what puzzles me the most. I don't understand why those in the salsa industry feel that their arrival at the "teacher" status means that they can no longer take classes. I find that in other dance forms you will find teachers readily taking the classes of those in their own field. It's an honor to be able to teach a class, and have others willing to learn from you, but that doesn't mean that you know everything. I find myself eating humble pie each time I attend an event and take someone's workshop. I learn more about teaching, about an explanation, or an interpretation of a move that I can use to improve on my own classes. It also puts me back into the student mode where I am forced to see things through the eyes of those that take classes with me.
Many people do reach a point where they think they know everything they should know and that they must be right and others wrong (in all things Salsa) - the "arrival" at the teacher status would be one of those points but some people don't need to become a teacher to have such attitude. Heck - I think I'm right most of the time.
disclosures -- I am not a Salsa teacher, am not taking classes right now, and don't expect to take classes anytime soon, but have no doubt some classes would be quite useful.
A question. What is a formal dance training anyway? Or put it another way, is taking something like Ballet class by definition formal dance training while taking Salsa class by definition is not a formal dance training? Is it about getting university credits? Or is it like "experts" know what is and what isn't by looking at it?
