It is true, that Arthur Murray had always danced the American Style "BOX" rumba with a forward step being the first step which was on a slow count. Fred's did the opposite and danced the first step as a step to the side on the count Quick. Independants have done this both ways, depending on the influence they may have had. The DIVIDA syllabus which is used alot anymore, dances the American Rumba like AM with the first step being a forward step on the Slow count. Myself personally, I like the Fred's way of dancing this with a side step first on the quick count. Whoever above who thought you were being taught Intl Style Rumba was wrong. If your teacher mentioned that Am did it this way, and fred's did it this way......there is no mistake that they are talking about the American Style "Box" Rumba. I do agree with whoever above said that your teacher is just trying to sell you that their way is right. I teach at a studio that uses the DIVIDA syllabus, and therefore for uniformity I will teach it with a forward step on slow as the first step. I grew up dancing Int'l Style, so I guess I really dont care. But I will teach it however the studio I work for wants it to be taught.
