Hi @BrandonK , I think I see what you’re talking about now, and that pertains to what Tony calls Finding The Key By Ear. The process as Tony teaches it is to have you play notes along the lowE string and try to match what you feel is the lowest chord sound in the song, because 99% of the time, that is the KEY in which the song is written. Once you’ve decided on the lowest note, then from there he wants you to play a major scale and/or a minor scale using that lowest chord sound as the root of that scale to see if the KEY is major or minor. I’m not sure why you want to use pentatonic scales, but that will work as well, provided you know the difference between a major pentatonic scale SHAPE and a minor pentatonic scale SHAPE. You should “Google” pentatonic scales. I think you’ll see that doing a major scale shape will be much easier, but like I said, the pentatonic scale shape will work also.
Good luck Brandon.
