Learning from the older generations
Compare those two interpretations of the variation of Giselle Act 1, by Dame Alicia Markova in 1951 and by Marianela Nuñez in 2011:
It's hard to say which one I prefer! I'm of my time, and Marianela Nuñez's Giselle seems more familiar. But Dame Alicia Markova's Giselle is so real! See how her head and neck are free and relaxed, how soft her arms are?
I wonder to what extent the acting and miming can be compared. Undeniably, they are of their respective times.
