I would like to propose a group of symbols used in tap dance notation.
Tap dancers perform percussion, on par with the vocals and instruments; and can be integral members of a band.

Bio & example:

http://samweber.org/id2.htmlI have the symbols scanned and can provide them, along with descriptions.
Getting dancers on the same page with musicians will improve timing, education and overall musical performance.
