What changes in Open F
The open strings spell F major with C in the bass and repeated F and C notes.
Make the tuning sound intentional
Play an alternating-bass pattern between low C and F while holding the open major sound.
Shape tip: Use open F, B-flat at fret five and C at fret seven; the low C creates a strong fifth in the bass.
Retune to C F C F A C safely
Most strings move down, so a medium gauge helps maintain clarity.
Change one string at a time, approach the target pitch gradually and recheck every string after the neck settles. Stop if a string feels unusually tight, the bridge lifts or the instrument reacts unpredictably.
