There is an article on the #wiki about #form (still a draft):
http://musicgames.wikidot.com/wiki:form

It covers structure of both #music and #boardgames and holds two print-and-play decks of cards for form which in our case is marked with:
- letters for repeated parts,
- apostrophes for variation,
- parentheses for optional repetition.

A question for #composers #musicTheory or #musicology people:
Do you know some common reused and describable forms, that may be notated like that? We need a lot!
