In the lesson 30 papa gates teach how to change between diferent pentatonic scales(over the chords C,D and G) in the same position and in the Syn´s tips says that try to play it in diferent “general” poitions and he tell us to play the D chord in the “G” shape and the chord in the “C” shape which are the both of them in the 7 position, right? but he also tells to play the C chod in the “E” shape but it isn´t in the 7 position ,it is the 8 position and i get confuse at these point,should i play the pentatonic scale of C in the 7 position anyway or play it in the 8 position??
