What notes are in the Cdim chord?
The Cdim chord is built from three notes: C, Eb and Gb (the root, minor 3rd and diminished 5th). Diminished chords are tense and dark, usually used as a quick passing chord between two others rather than on their own.
The Cdim chord belongs to D♭ Major (the vii°) and B♭ Minor (the ii°). Each key page shows the rest of that family, the progressions that use it and songs to play.
