Yes– its in the “C Minor Scales in thirds up & down the strings” in the “mastering the fretboard” Course. I can technically perform the exercise, but I’m trying to wrap my brain around it more. I’m mainly getting hung up on the change in pattern & intervals from the other harmonic thirds exercises. For instance, it is going from C to A, then next D to Bb (which is technically the minor 6th, not the minor 3rd). I might just be missing something here. I enjoy the exercise, but am trying to understand it a bit more.
