Sylvia's description of a Gypsy is substantially correct. The movement
involves two dancers circling all the way round each other, remaining facing
each other the while. It is, however, much less ambiguous to refer to it as a
"clockwise Gypsy" or "anticlockwise (counterclockwise) Gypsy", rather than
using the terms "left shoulder Gypsy" and "right shoulder Gypsy".
The movement involving moving forward to stand side by side with
partner is known, quite simply, as "siding"! Playford uses the instruction
Oh, and yes, the movement required in the Wood Duck is the Gypsy
described above and by Sylvia.
