Hi Francisco (et al),
This chord is exactly as common as the \key aeses \minor (14 flats) signature.
Incorrect: the G-flat diminished 7th chord could easily appear in a descending sequence (e.g., resolving to an F sixth chord).
I don't have an engraved example off the top of my head -- and I certainly don't have the time or interest to find one for the list -- but I would be FLABBERGASTED if there aren't NUMEROUS examples of this exact chord in published music written since 1850. In particular, Romantic and post-Romantic solo piano music, and 20th Century French pipe organ music, are likely gold-mines of G-flat diminished 7th chords.
To claim that an F-double-flat is only as common as a 14-flat key signature is simply untrue.
Best wishes, Kieren. _______________________________________________ lilypond-user mailing list lilypond-user@gnu.org http://lists.gnu.org/mailman/listinfo/lilypond-user
