“The Double Branle has a simple form involving two phrases of two bars each. This form was not sufficiently different from the pavan to be of interest to composers and so pieces with these names rarely occur in the instrumental books of the time unless they are specifically designed for dancers.
The Single Branle, however, consists of a phrase of two bars, followed by a phrase of one bar and appears in numerous places. Likewise the Gay Branle consists of two phrases of two bars each, but in 3/4 time, and so was also widely used.
The Burgundian Branle as described by Arbeau is of the same structure as the Double Branle, but played with a lighter feel. Musical sources however often give an irregular structure for this dance.”
