...I have noticed over the decades now since Balanchine died, that the headlong tempi to Snow and Flowers have abated somewhat, at least in the initial periods of the dances. Flowers used to rush along until the last ten notes - onetwothreefour FIIIIIIIIIVE~ sixseveneightnineten! No more. Pity! I used to like that fermata.
My first viewing of Balanchine's must have been in 1958, because I distinctly recall being ten. My latest viewing was in 1998, and I haven't been able to get back since, although I've keenly wanted to. It's really slower than it used to be.
