Tips for playing B♭dim on guitar
On guitar, B♭dim has an open-position shape, x12320, using four fingers alongside the open strings. Don’t strum the low E string.
Notice the F♭ in B♭dim (B♭ D♭ F♭): each note of the chord takes its own letter (B–D–F), so the diminished 5th has to be written F♭ rather than E — the same key on a piano, spelled to fit the chord.
