Here again, I think point of view is the key. If you decide which
head you're inahbiting, then what bits of choreography are
narrated, and in what terms, will come clear.
Also, don't forget you
don't need to narrate the whole
dance, step by step. You're telling a story, and what and how you
show us of the action (audience as well as dancer) will depend on
what the story that you're telling.
For example, if his ex-lover is standing in the wings then
pas
de chat that brings him face to face with her is tremendously
important; before it, he'll be knowing that it's coming, and
wondering if she'll be there.... and then she's there, two feet
away crying (or laughing).... and then the choreography means he
jetés away to the other side of the stage, where his new
lover in the corps de ballet is standing, and he knows that his ex
can see them as they join hands and do what the choreography
demands, and the new girl knows it, and goes all self-conscious and
stumbles... But he might be too preoccupied with all that to
specially notice that the audience is hugely enthusiastic tonight,
or not... Whereas another dancer who's worried about whether she's
going to keep his job with the ballet might be noticing every cough
and snuffle, and counting how many curtain calls there are, and be
oblivious to the love-triangle...
Some of the way you narrate all that would include the ballet
terms, and some wouldn't - it depends on the point-of-view. I know
my daughter had a collection of ballet stories (not the stories of
the ballets, but stories about people learning/doing ballet) when
she was a bit younger, which would be worth a look (I bet your
library would have something like that). Even though they're
written for children and younger teens, it would give you an idea
of how to use technical terms in the story so they they make it
more believable, but don't sink it.
This kind of thing:

They're not all great writers, but they're usually good
storytellers.
