Static Animation

Ok I know all about how to make a 2 or 3 frame static animation..

What I want to know is - is there any way to hold a pose at the end of say a 30-40+ short dance/walk/etc.. animation?

as example...

ballet. - where you spin through the pirouette and come up on one leg, other extended back, arms out before and behind (swanish) - can you hold it in that pose statically. so that *as example* you could then choose from a number of animations that start from that poistion but carry on in different directions (sorta of a create a dance on the spot concept)
