As Jerry Jennings previously explained, the minor pentatonic is only useful if you are aware of where the root is. By playing single octave versions, you are playing from root to root (root=tonal center). This new song will be nothing but playing from root to root and back, in the A minor pentatonic. The first version is with the lower single octave, and the second is the higher single octave. 6:29 minute video lesson with PDF file.
