6ths on the G & high-e strings: walk I→IV and I→V.
Key of G. Numbered dots = play order. Start on a G grip (rust), land on the
green grip on the downbeat of the new chord. Amber = chromatic slide — touch it on
the upbeat, never stop on it. To come back (IV→I, V→I), run the same path in reverse.
Home — a G grip
Passing — keep moving
Chromatic — upbeat only
Landing — both notes in the new chord
G → C (I → IV)
Ascending
Timing: steps 1–2–3 on beats 2–3–4 of the last G bar, the chromatic
slide on the "and" of 4, land on beat 1 of C.
Descending
Timing: step 1 on beat 3, step 2 on beat 4, the chromatic slide on the
"and" of 4, land on beat 1 of C. Open strings on the landing — let them ring.
G → D (I → V)
Ascending
Timing: step 1 on beat 3, step 2 on beat 4, the chromatic slide on the
"and" of 4, land on beat 1 of D.
Descending
Timing: step 1 on beat 3, the chromatic slide on the "and" of 4,
land on beat 1 of D. Short walk — the V is close to home.
