Anonymous, I had indeed forgotten about Bournonville when I asked the question. But the question was prompted by actual experience. I go to two different studios for classes that suit my schedule and skill level. On Mondays and Saturdays I have an instructor who was trained by a dancer who was taught by Vaganova herself. In these classes, I'm perfecting (or trying to, at least) something that Ms. A calls "flic-flac."
The moving leg begins at sur le cour-de-pied on the front of the supporting leg and whips out, very quickly, into second. The movement does brush the floor a little bit, but doesn't seem to be a true frappe. In any case, the leg returns just as quickly to sur le coup-de-pied, but behind the supporting leg.
On Tuesdays and Thursdays, however, Ms. K calls the exact same thing the "royale." Ms. K was educated at North Carolina School of Dance and has been all over the map as a professional dancer. But she hasn't proclaimed herself to be a disciple of any single school. She did explain the fascinating provenance of the royale.
It is so-called because it was introduced by the Sun King himself, who was having trouble while trying to learn something else (I forget what, though). The royale wasn't exactly cheating, but it was an incomplete version of this other thing. Rather than show up the king or correct him, Louis's courtiers immediately began to imitate what he was doing, and so it was named and became a standard.
Now, though, if the Russians call this movement "flic-flac," who calls it "royale," and are there yet other terms for it? [/i]
