chords grid

Général

hi everyone

i now use the following code for having some grids

i guesse that i can transpose them easily with the instruction \transpose

so, that is much more interessant as typing theses chords in an usual text editor

for the lines i will superpose it into my text/vectorial editor

now my question is :

how to put two chords in a single case ?

it is very frequent for improvisation ot have somethign like that :

C | D/F7 | G | Am

the "D/F7" indicatves that half the time of a case it is D and the other half is F7

in Lilypond i can indicate d:/f that means chord D with bass note F, but that could be convenient for having D for half and F for other half of the case
now how could i have D/F7 ? because Lily will not accept d:/f:7

Bonjour,

Je suppose que tu parles aussi français car ici c'est Lilipond French Users
:wink:

Cela fait un moment que je cherche a faire des grilles avec lilypond et j'ai
trouvé une solution.
La notation avec une barre oblique prête a confusions (accords avec basse
différente) et je pense qu'un affichage avec un espacement proportionnel est
suffisant dans la majorité des cas. Quelques annotations rythmiques sous la
grille peuvent aider a expliciter.

Bref j'ai fait ça:

%------------------------
\version "2.14.0"

\paper {
  indent = 0
  system-system-spacing #'basic-distance = #20
}

structure = {
  \key e \major
  \mark \markup \box "test"
  s1 * 4 \break
  \bar "|:" s1 * 2 \bar ":|" s1 * 2
}

accords = \chordmode {|
  c2 c2:7 r8 f4. f2:m c2:7 f:7 c1:7 |
  c1 f c2 f2 g1
}

rythme = {
  \stemDown
  b8 b16 b16 b4 b4. r8 r8 b4. b2 b2 b2 b1
  s1 s1 s1 s1
}

\layout {
  \context { \Score
  \remove "Bar_number_engraver"
  proportionalNotationDuration = #(ly:make-moment 1 8)
  }
  \context { \ChordNames
    
    \override ChordName #'font-name = #"Deja Vu Sans"
    \override ChordName #'font-size = #5
    
    noChordSymbol = #(make-simple-markup "-")
    \override BarLine #'bar-extent = #'(-2 . 5)
    \consists "Bar_engraver"
    \override VerticalAxisGroup #'nonstaff-relatedstaff-spacing #'padding = #0
  }
  \context { \RhythmicStaff
    \override NoteHead #'style = #'slash
    \override NoteHead #'font-size = #-2
    \remove "Time_signature_engraver"
    \remove "Bar_engraver"
  }
}

\score {
  <<
    \new RhythmicStaff \with {
      \override VerticalAxisGroup #'staff-affinity = #DOWN
    } \structure
    \new ChordNames \accords
    \new RhythmicStaff \rythme
  >>
  \layout {}
}
%------------------------
Un peu d'analyse devrait permettre d'adapter a tes désirs.

Cordialement
