About Gb diminished
Gb diminished is built from three notes: Gb (root), Bbb (minor third) and Dbb (diminished fifth). Its interval formula is 1 – b3 – b5. Its diminished fifth adds a marked tension; it works as a passing chord, very common in jazz and classical music.
Gb diminished has no standard open shape in the CAGED system, so its 17 voicings are sorted only by difficulty and position on the neck. Gb diminished is also written as F# diminished: the same chord with the root spelled differently, and it sounds identical. The more common spelling is F# diminished.
