@BanjoBen (or other experienced forum members),
Can you help me with a notation question.
I am writing a song in the key of G. I have a place where I want to step up from a C (IV) Chord to a D (V) chord… using a C#, E, G diminished chord as a transition.
Since a diminished chord, by definition, is 3 semi-tones (3 piano keys) - or 1-1/2 steps…
As you know, the 4 notes in this diminished chord are: C#, E, G, A# within 1 octave and repeats up or down to the next octave.
I also know from theory, the only “natural” diminished chord in any MAJOR key is the 7th (F#, A, C in the key of G major) - which doesn’t apply here.
Therefore, how would this typically be called out in the key of G for notation purposes within the G progression?
So I am not sure what to call it as an altered number chord in they key of G???
Is it a 4 altered chord (c#-dim)? Is it a 6 chord (e-dim), a 1 chord (g-dim) or an altered 2 chord a#-dim?
