> I am on the lookout for a suitable software to record (choreograph??)
Some systems to write choreographic scores do exist ... they are much more
sophisticated than stick figures! I have no idea if there is any software to
typeset them ... probably not, it is a rather specialised field. In practice,
ever since video cameras became affordable for a rehearsal room, a fixed shot
covering the whole stage has been the usual way to learn and document dance.
Written scores mostly date from earlier than that, though there are exceptions.
