Definition of pas de bra ballet movement?

Answer 1

I think you mean port de Bras. It means 'movement of the arms' and involves moving the arms through different positions in a continuous and graceful movement.

A basic port de bras is where the arms go from bras bas, to first, to second, then back down the bras bas.

A full port de bras is where the arms go out to second, then as you fold down, keeping your legs straight, the arms lift to 5th.

Here are all the arm positions I can think of - bras bas, 1st, 2nd, 3rd, 4th, 5th, 1st arabesque, 2nd arabesque, 3rd arabesque, open 5th, demi seconde, demi bras, and also many more will be used in Ballet routines that don't have names.
