This practical note presents a central-outward first pass for tuning a standard six-string guitar. The proposed order is 4 -> 3 -> 5 -> 2 -> 6 -> 1, corresponding in standard tuning to D3 -> G3 -> A2 -> B3 -> E2 -> E4. The note frames the order as a simple tuning route for reducing return corrections: tune the center strings first, move outward to the adjacent strings, and finish with the outer strings. The claim is practical rather than theoretical; the order is intended as a baseline first tuning pass before ordinary fine corrections.
