Diminished 7th chords are symmetric. Each one could be the same quality chord on any root note that is a chord tone inside it. So, is there agreement on which name to use for these chords? I know that a lot of chord charts will just use whatever root note is convenient (or usually not convenient)
I know there's a bunch of ways to use them. When using one as a passing chord, would it make sense to say F-F♯dim7-G in the key of C? Do I call it F♯dim7 because the F♯ is like the leading tone to G? Or something else?
What if I use one in a different way? How do I know which of the notes should be called the root? (And I suppose this question would also apply to augmented triads as well...)
