Examples 5-7 involve two-string lateral motion on the top two strings. Ex 5 starts in shape 2, before shifting up to shape 3; then descends through shapes 2 and 1. The two-hand tapped combination in bar 18 shifts from the second string to the first then back to the second, before sliding on the first finger up to the next position and repeating the same principle. Visually, if continued up the length of the neck, this motion traces out a shape similar to the teeth in a comb. By sliding down the neck with the first finger each time, this ‘comb-teeth’ combination can also be used as a means of descending. As usual, all basic movements can be embellished in various ways. Here, each 17-note motif comprises a basic nine-note motif (notes 1- 8 and notes 15-17) that has been expanded by a six-note ‘insert’ (notes 9-14). Try seeing how many other ways you can expand the basic movement with your own inserts.
