Thank you so much for your elaborate clarification, Christopher. Btw, I am getting so much from your lessons on Guitar theory -- Major and minor scales, harmonizing the scales, triadic harmony, key signatures, etc. In fact, in the interim between writing the original post on this forum inquiry and the present, I've watched enough of your lessons to understand that there are many ways of performing a chord. My point is that I'm getting a lot out of your lessons. Thank you!
