Here are links to some dance descriptions (or collections of dance descriptions) that are available on-line. In many cases these are the full instructions, published by the dance devisers, but some of them are reworded “cribs”, so caveat emptor applies (or should that be caveat downloader?).
If you have anything to add to this page then do let me know!
