Topic: Diminished chords
I am not really a guitarist, but I do a lot of arranging and some composing and I like to include guitar fingerboard diagrams in my scores. I have a chart of these diagrams that I got online somewhere some time ago, and I just noticed that every diminished chord in this chart includes the 7th. It is not mentioned in the chord label. For instance Edim is one label, but it should really have been Edim7dim. Is that something peculiar about guitar chords? Do all diminished chords on a guitar include the dimished 7th?
