Diminishing Perspective - A Diminished Scale Line
Because the diminished scale is devoid of avoid notes, and due to its symmetry, is essentially polyphonic in nature (hosting 4 Major and 4 minor triads, 4 dominant 7th chords, as well as 2 distinct non enharmonic diminished 7th chords), a single tonal center can be somewhat ambiguous and not always immediately apparent. Nor does it need to be.
However, for the purpose of this exercise, letting my ear be the guide, a tonal center was chosen which felt natural, with alternates, based in the same diminished 7th chord (listed in parentheses).
They all "work", in both theory and practice, and are only suggestions in any case.
