The emphasis sounds to me to be on the downbeat, a six note phrase beginning on each downbeat. The first six note phrase begins on the three of the scale; thus 3-1-2-3-1-2. The next phrase is 3-4-3-3-2-1. The third is 6-5-4-3-4-5. The last is 6-3-2-4-3-2, where the 6 is below the 1. Or that's my guess in listening to it phrase by phrase; I haven't tried to play it.
