Re: error in predefined chord diagram?

[bart deruyter]

Indeed, it would be much more clear if the notes should match the fingering, but then the notes should be adjusted, not the fingering But then the basic structure of a chord gets much less clear. It already was suggested both could be shown in the presentation.

Chord diagrams are actually almost only used in popular music, which is, when it's about guitar, mostly based on chords. These chords are basically shortcuts, to grab them quickly. When it's about these predefined chords, we're talking about these quickly to take chords. They almost never are only the 3 notes of a chord, with this I mean, without doubled notes.  

To be even more perfect, these notes should appear in the right order, because we otherwise could have inversed chords, and these  are named differently too (D/F# for example... 200232). Then almost all of the suggested diminished chords will have to be changed, to a more difficult to grab chord, including all those other chords we even haven't looked at.

If only fingerings are shown that are 100% theoretically correct, we end up with a chord list nobody uses, and the purpose of the predefined guitar fretboards is gone. Though extending the chordlist with these inversions would be nice too ;-) .

That's why, I thought at least, these predefined chords are created, to make it possible to quickly write them down in lilypond. When it's about theoretically 100% perfect chords people still can create their own fret diagrams.

Let's stick to the purpose of these predefined guitar fretboards.

Here an example of how it could change :


\include "predefined-guitar-fretboards.ly"

Chords = \chordmode {
e:m
}
notes =  {
\relative c

{
<e, b' e g b e >1| <e' g b>
}
}
\score {

<<
    \new ChordNames { \Chords }    
      \new FretBoards { \Chords }

     \new Staff{   
       \clef "treble_8" \time 4/4 \notes
      }
>>
}

There is a fourth note, double one of the notes in the triad, in the dim fingerings that is not in the score.  IME the fingering should match the score in cases where there is a score.  The dim chord is a triad so the fingering should contain only those three notes with none of them doubled; the dim7 is a tetrad and the fingerings correctly contain those four notes.

This may be overly pedantic.

As I see it, as far as I've seen the pdf, the fourth fingering is doubling one of the notes of the chord, which is perfectly valid, and not playing a fourth note in the chord, as the previous version did, which resulted in a 7th. A regular C chord doubles the c and e too, a regular E even has 3 e notes.
