I am obsessed with this tune, a scottish/valse called “Le Cotillon Vert.” Here I am in my kitchen taking a crack at it.
The scottish/valse is exactly what’s on the tin. You dance the A section as a scottish (medium tempo, 4/4 dance), then you switch to a waltz for the B section. Then back to a scottish. Then waltz. Et deliriums cetera. The trick — and it is tricky — is that the ones of the scottish have to be the same distance apart as the ones of the waltz. So, the 1-2-3-4 of the scottish has to fill the same amount of time as the 1-2-3 of the waltz. Got it?
“Le Cotillon Vert” is a bedeviling ear-worm of a tune. A bog norm standard that I found in Sylvain Piron’s tradfrance. Here’s the sheet music:
