What notes are in the Gbdim chord?
The Gbdim chord is built from three notes: Gb, A and C (the root, minor 3rd and diminished 5th). On the ukulele the A is doubled, so you get a nice full sound. Diminished chords are tense and dark, usually used as a quick passing chord between two others rather than on their own.
The Gbdim chord belongs to G Major (the vii°) and E Minor (the ii°). Each key page shows the rest of that family, the progressions that use it and songs to play.
