Tips for playing G♭dim7 on guitar
On guitar, G♭dim7 has an open-position shape, 20121x, using four fingers alongside the open strings. Don’t strum the high E string.
Notice the B𝄫 in G♭dim7 (G♭ B𝄫 D𝄫 F𝄫): each note of the chord takes its own letter (G–B–D–F), so the minor 3rd has to be written B𝄫 rather than A — the same key on a piano, spelled to fit the chord.
