Dance Etiquette Tip #2 - When on the social dance floor, during a social dance, it is poor manners to correct a fellow dancer. However, should a fellow dancer ask for your critique, you may offer one or two tips. More than one or two suggestions can be overwhelming to a new dancer and may take too much time away from actual dancing.
Dance Etiquette Tip #5 - When in a dance lesson, it is best to allow the teachers to do the teaching. If class members are trying to teach each other during the lesson, it becomes very difficult to hear the instructors. As members of a class, please remember that we are all learning (or refreshing our learning), so please address any questions to the teachers and not to your fellow classmates during the lesson.
Dance Etiquette Tip #6 - When in a dance lesson, there are times when the instructors may request feedback from class members, or you may have a question. If you have something to offer, it is best to phrase your comment (or question) as a question, so that the instructors may address the problem for the good of the group, especially since the instructors are the leaders at that time. Also consider the benefit this allows to new instructors as they learn how best to explain the movement and leading & following.
