What a diminished seventh chord is
In plain terms, 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.
