What changes in Open B-flat
The open strings form B-flat major over an F bass, repeating the root, third and fifth.
Make the tuning sound intentional
Strum the open chord, then play a slow I–IV–V using barres at frets five and seven.
Shape tip: Use the open chord as B-flat, fret five as E-flat and fret seven as F.
Retune to F Bb D F Bb D safely
The low string rises a semitone while several upper strings move down; use suitable gauges and tune carefully.
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.
