“… bring in freelance dancers for productions requiring a large corps eg Swan Lake, Rite of Spring.”
O yes, freelance dancers of all sorts might be brought in to make large corps for “Rite of Spring”! Modern, classical, contemporary, “hip hop”, “random”, etc. Not enough of those, bring Flamenco and incredible Chinese acrobats. They all will grasp and master “Rite of Spring”.
One can not do it with “Swan Lake”. I don’t mean the 64-swan version performed at the arena but the stage version, which can not be thoroughly enjoyed without perfect performance by the corps. Perfection of the corps can not be achieved with temps. Don’t we know that it takes years, even decades to achieve perfect lines, uniform style and united breath of the corps? In order to remain a classical company the ENB, like any other troupe, must maintain full size corps de ballet. IMHO
