I have a fretboard problem.
I have defined a new fretboard for a plectrum banjo. Everything is working
properly when I specify a chord, except when I specify a SLASH chord, i.e.,
a chord with a designation for the bass player. So for example, if I specify
a G half-diminished chord, all is well. But if I specify a G half-diminished
chord with a D-flat in the bass, I get a fretboard fingering I don't recognize.
Okay: g:m7.5-
Not okay: g:m7.5-/dflat
Basically, I think the chord in both instances (with or without the slash
notes) should be exactly the same fingerings. How can I correct this?
Here's an example below:
\version "2.19.15"
\include "english.ly"
%% tunings for 4-string banjo
\makeDefaultStringTuning #'plectrumTuning \stringTuning <c g b d'>
\storePredefinedDiagram #default-fret-table \chordmode {c}
#plectrumTuning #"o;o;1;2;" % C
\storePredefinedDiagram #default-fret-table \chordmode {g:m7.5-}
#plectrumTuning #"5;3;2;5;" % Gø
chordNames = \chordmode {
c1 g:m7.5- g:m7.5-/dflat
}
melody = \relative c'' {
c1 c c
}
\score {
<<
\new ChordNames \chordNames
\new FretBoards \chordNames {
\set Staff.stringTunings = #plectrumTuning
\override
FretBoard.fret-diagram-details.finger-code = #'in-dot
\override
FretBoard.fret-diagram-details.number-type = #'arabic
}
\new Staff { \melody }
>>
}
