New input case for you: I have been taking Belly Dance lessons for several years. I found this tape very helpful and the instructions clear. I think the intent of the tape is to introduce certain movements and let the viewer be creative. So if you are looking for a full workout you will not get it from the tape. You have to make your own. But that is one of the beauties of the tape. If you want to dance in the privacy of your home or if you are thinking of taking lessons, I think this would be great for you. It is a very gentle tape. Do not be fooled by the 1996 date listed here. That must be the reprint date, my tape said 1985 which explains the dated hair and makeup. Atea is not the most animated speaker but I think that is in line with gentle nature of the tape. I think the tape is very much in the spirit of belly dancing as it encourages the viewer to use her own style.
Output:
Positive
