Work on singing and playing the six notes B,C,D,E,F,G that we’ve learned and used on the B and E strings. Practice them in different combinations, going up and down, one string or both, mixing up, etc.
Work on 17 with good posture and an emphasis of focus.
Practice occasionally with eyes closed once you have 17 memorized.
Keep working on chords. Work on new pairs if possible.
