Tips for playing B♭dim7 on guitar
On guitar, B♭dim7 has an open-position shape, x12020, using three fingers alongside the open strings. Don’t strum the low E string.
Notice the F♭ in B♭dim7 (B♭ D♭ F♭ A𝄫): each note of the chord takes its own letter (B–D–F–A), so the diminished 5th has to be written F♭ rather than E — the same key on a piano, spelled to fit the chord.
