Watch the C Minor Pentatonic online guitar lesson by Brad Carlton from Guitar Lab: Scale Form Logic Vol. 1

The five forms of the pentatonic scale move up the neck via the octaves of the root of each form. In the previous lesson, we dealt with the sixth string root form. The octave of any note on the six string is always two frets higher in two strings over (which would be the the fourth string). Another important consideration is how the pentatonic scales fit together like puzzle pieces as you move up or down the neck. This introduces the concept of the "sides" of each pentatonic scale form. Thus, the high side of the sixth string root pentatonic is the same as the low side of the fourth string root pentatonic.
