LH walks 1–3–5–8, RH stabs rootless chord on 2 and 4
The hands divide labour: the left walks the bass
in quarter notes (root, 3rd, 5th, octave — the chord stretched
out as a line), and the right comps on beats 2 and 4
with the rootless A/B-form voicing, resting on beats 1 and 3 so
the bass line breathes. This is what a pianist does in a duo (no
bass player) — cover both functions at once.
The 1–3–5–8 shape is the simplest walking line: the chord
tones stacked in order. Real walking bass is improvisational, with
chromatic approaches and passing tones; this is the skeleton.
Once it's automatic, swap in approach tones on beat 4 — for
example, instead of returning to the octave, play a half-step
below the next chord's root.
LH
Walk 1 → 3 → 5 → 8 in quarter notes.
