I’ve been working on the 3rd Rabbath book and am unsure about the bow stroke variations suggested for playing the scales and arpeggios. Could someone explain the difference between the 2 groups of slurs below please? To add to my confusion I can only see 7 variations in each (slur in groups of 2,3,4,5,6,7 & 8) rather than the 8 that the numbering suggests. This pattern of slurs above & below followed by just above the notes is repeated quite a few times over the 282 variations. Though I’m unlikely to find time to try all of them (I’ve already spent about 2 months just on 3 octave Gb/F# scales with long notes against a drone) it would be nice to know. I'm hoping the answer isn't "it's explained on page x" but it wouldn't be the first time I've asked someone in the supermarket where the beans are while stood right in front of them. I have tried searching online and in the books I have at home.
