I've excerpted sections of Chapter 20 of The Hidden You by Mabel Todd for the sole purpose of education. These selections are presented here so that others can listen to her descriptions of movements and perform and practice them.
For more about Mabel Todd or to purchase her books, please consult the Thinking Body Institute.

The TBI Special Editions are high-quality reproductions of Todd’s original works that preserve their original character and aesthetic and are of much higher quality than the array of reprints available elsewhere. Plus, the proceeds from the sales of these and all other materials listed in their online store are used exclusively to promote the aims of the Thinking Body Institute.
