The notes in Cdim7
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: C (R), E♭ (♭3), G♭ (♭5), B𝄫 (♭♭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.
