Dave/Andrew - thanks for the encouragement. It has sparked up my interest as well.
One GREAT thing about this exercise is that she (and I, as a spectator) could HEAR immediately if she missed a note. The arpeggios made things more noticeable.
I am thinking about buying a beater bass to leave on her porch so I can join in... ;-)
One negative, the instructor's Zon has no front fretboard dots. This is a slight handicap when trying to explain positioning to the student (who has dots). But she is getting it, even so.
