Watch the Minor Seventh online guitar lesson by Kai Eckhardt from Atomic Bass: Reactive Intervals
If you can remember the old Star Trek theme with William Shatner as Captain Kirk, you will have heard the minor seventh soaring through space the final frontier, played by a full orchestra. (First two notes of the theme). Now the interval is so large that you can only play one octave before you run out of space on your instrument. Inversion to the rescue. The major second elegantly weaves in and out of this drill to create a crazy loop that will surely turn your fingers as loose as a rubber band.
