OK, OK, now here comes my thought: IF a diminished seventh chord has
its origin in a minor ninth dominant chord --common in minor keys--,
without its base (the dominant itself), THEN a feses is the minor
ninth of the dominant eses, whose corresponding tonic is aeses and
therefore our key is aeses minor.

Note the IF-THEN that gives aeses as result of a 'logical' or
'natural' explicit key signature where could happily live this note.

What a great OT!
