The notes in B♭dim7

RB♭♭3D♭♭5F♭♭♭7A𝄫

Because the uke's high-G string is re-entrant (it's a high note, not a bass), these notes don't stack low-to-high like a guitar — but the chord is the same: B♭ (R), D♭ (♭3), F♭ (♭5), A𝄫 (♭♭7).

What a diminished seventh chord is

a diminished 7th stacks three minor thirds (root, ♭3, ♭5, ♭♭7) — perfectly symmetrical, so it can pivot to almost any key.

How it's used: A slippery passing chord: because every note is a minor third apart, one shape covers four different roots, and it can lead almost anywhere.

The sound: Maximum tension, mysterious, cinematic — the classic 'something's coming' chord. Where you'll hear it: Jazz passing chords, silent-film suspense, neoclassical metal, gypsy jazz.
