Hi everyone! Last week I've been to a workshop, and at some point the lecturer asked the following question: "For the C major pentatonic, what are all the substitutions you can make?" After some back and forth he ended up not answering the question in a concrete way and I was left with this in the back of my mind. I actually know that for a major pentatonic I can use both the pentatonic of the fifth and the second (up a tone) pentatonic as a substitution. Something tells me that I might be able to use the relative minor pentatonic also, but I'm not sure of that. Having said this, can someone help me with this? What are "all" the substitutions I can use for both the major and minor pentatonics?
