In my experience, WCS is danced socially at a C&W place by getting out on the floor early in a song and staking out a slot on the edge of the floor away from the gaggle of line dancers hoping that the late arrivals will respect my slot and realize that their box will end up where I am while I have no place to go.
Maybe someone can comment on some not country waltz music. In the meantime...
I heard the Roger Miller original of Husbands and Wives while on a CostCo run with my friend.
I noticed a long time ago how CW drummers accented what I thought were the 2nd and 3rd beats, and hey isn't the first beat in waltz the one that is emphasized?
Here's the Brook and Dunn version that I've always danced to. Sounds like the drummer is mostly hitting the 3. I was able to find sheet music on line to confirm the not always but when it happens it's on 3 here.
I listened to Patsy Cline's Tennessee Waltz (originally by Pee Wee King), and there was the same drummer on 2 and 3. With this one it seems like the drummer is playing n 6/8 to accent when he does.
The idea is to let the downbeat resound with a bass note. So the drummer tends to hit the bass drum on the downbeat and hits the trebles (brushes, hihats) on the 2 and the 3. I have heard some drummers accentuate the downbeat with a rimshot, like Rick Ament. I find that those who give the treble to their downbeat tend to take away from the push and pull that one normally associates with the waltz.
