It is by no means an authoritative guide, but more of a snapshot of my (novice) current understanding of the idea. Feedback & contributions are welcome!
Lead projection in West Coast Swing is the technique of foreshadowing the upcoming movement (pattern) through positioning within the slot, adjusting the pitch, rotation, etc at the end of previous movement.
Lead Projection is also sometimes referred to as "pre-leading" or "slot dynamics"
You create a projection by adjusting your position, pitch or rotation at the end of preceding pattern (~through last 2 counts of it)
Projecting Direction
People often talk about slot as "train tracks" - you can imagine leader stepping onto one of the rails or staying in the middle as a way to indicate the direction of next pattern to the follower.
If leader is in the middle of train tracks - blocking the way of the follower - that implies a blocking pattern is coming (e.g. sugar push or sugar tuck)
If the leader is off to a side - they are inviting the follower to pass on the other side of them
Example: leaders offsetting to their right at the end of the pattern invites follower to pass on their left (e.g. left side pass) for the next pattern.
Up and down (pitch) projection
by.., you can indicate whether next pattern would have a higher or lower focus
Higher focus usually involves turns of some kind (sugar tuck, underarm pass, inside roll)
Patterns with lower focus is when your connection point stays approximately at it's default height (sugar push, left side pass, whip)
Letting hand come out/rise to project up
"breathe in"
up & down (pitch) projection from ESS Camp
subtle - breathe in/out
Projecting Rotation
You can think of projecting rotation as a form of prep that is shifted earlier in time/incorporated into previous movement
Lead projection is not necessarily something you do deliberately. Sometimes it happens that you naturally end up, say on a side of the slot as you're completing a movement (or over/under-rotated).
People often have an instinct to "square up" to their partner, as they anchor, in such a situation (negating rotation, moving to the center of the slot).
But you can also interpret that as "naturally occurring" projection, and pick a new movement based on the position in the slot and an angle you've developed. Arguably doing this can create a better "flow" in the dance.
things people miss
keep hand "in the slot"
instead your connection point should stay approximately the same place as if you were anchoring normally
you turn out your body to offset
sufficient? need to turn wrist too
keep connection point neutral
presumably if you gonna lead inside roll from the left or otside on the right - this is where you want to project both side and rotation
whip also requires rotation
When leader is directly in front of the follower at the end of the pattern (blocking their way through the slot)
When the leader is offset to the left side of the slot
Inspired by Joel Gibson's notes on the topic.
implications?
projection from the follower side
request for pattern on that side
important to do it at the end bc otherwise leader will match you to get square ish
