Eyewitness Books, from DK Publishing, is a wonderful resource for young readers. This particular volume focuses on dance. Each topic covers about two pages, providing a basic perspective and then some examples. This book begins by defining the subject (Page 8): "Dance is a series of movements performed in patterns and set to an accompaniment. Every human society practices dance, which may be performed solo, in couples, or in groups."
Some of the more specific subjects? On pages 22-23, we see a discussion of beauty and strength. The text notes that what one society sees as beautiful dance may be defined as ugly in another (teaching the rader to understand the culture specific definitions as to what is beautiful).
Another subject is "Behind a Mask" (pages 32-33). The text speaks of the use of masks in dance in many cultures, and there are illustrations to suggest the variations in use of masks.
Finally, on pages 54-55, there are examples of famous dancers--from Fred Astaire and Ginger Rogers to Vaslav Nijinsky to Rukmini Devi.
All in all, a nice resource for young readers who might be interested in learning more about dance.
