Watch the Minor Seventh online guitar lesson by Kai Eckhardt from Atomic Bass: Reactive Intervals

This variation is another sonic adventure charged with suspense. When you play it as it pivots back and forth between two tonal centers (A and G) it gives the impression of a never ending staircase. Careful observers will remember the major second and it's popular use in suspense movies. Well, the minor 7th is an inverted major second, thus the sonic quality of this drill is very similar to the one you already know.
