This is meant to be a supplement for the Art of Body Singing Volumes 1-4. It's designed to help get a rhythm going with the several techniques and exercises presented in the program until you can practice them by ear without the aid of an instrument or recording.
There is no explanation for the exercises (as that is of course found in The Art of Body Singing Volumes 1-4) so it's not recomended to buy this program by it self.
