02 Feb 05 - 06:44 AM (#1396691) Subject: Theory: Double flats in chord names? From: GUEST,pavane I am trying to establish whether this is necessary to include in my program. Sometimes, particularly when a tune is written in a key signature requiring several flats (or sharps), a double flat (or sharp) is required within the score. I imagine that in theory, if a chord is based on this note, it would also have to have a double flat in its name. Thus I suppose that, for example, Gbb7, or C##maj7 would be possible Has anyone ever seen this in real scores? Would I have to allow for it when transposing? Or can I just ignore it? What do other programs do? |

There are perfectly valid reasons for double sharps and double flats in tunes, and within chords, but no need for them in the actual chord names. Although technically for example a tune in C minor which had a B7 in it would, if it were transposed to G sharp minor, need a F-double-sharp-7, this would be the same as a G7 and no-one in their right mind is going to worry about the difference. |

From: GUEST,MTed Actually, T-Boy, I think, in your example, the chord *would* be called a G7, because with that change, the melody would have passed into another key(the key of F#) and the g would officially be called a flatted ninth, it would be functionally a passing chord in the dominant harmony( V7b5)--a key change like this(which actually happens a lot) is virtually never shown in the key signature, it is indicated with accidentals. From my own experience reading chords from sheet music,the- copyist will often paste the name of some random diminished chord, and leaves it to the chord player to deal with it as best as possible--Sometimes, they even leave it blank-- |
