Vertical lines can be drawn between staves synchronized with the notes.
The Grid_point_engraver
must be used to create the end
points of the lines, while the Grid_line_span_engraver
must
be used to actually draw the lines. By default this centers grid
lines horizontally below and to the left side of each note head.
Grid lines extend from the middle lines of each staff. The
gridInterval
must specify the duration between the grid
lines.
\layout { \context { \Staff \consists "Grid_point_engraver" gridInterval = #(ly:make-moment 1 4) } \context { \Score \consists "Grid_line_span_engraver" } } \score { \new ChoirStaff << \new Staff \relative c'' { \stemUp c4. d8 e8 f g4 } \new Staff \relative c { \clef bass \stemDown c4 g' f e } >> }
Grid lines: changing their appearance
The appearance of grid lines can be changed by overriding some of their properties.
\layout { \context { \Staff % set up grids \consists "Grid_point_engraver" % set the grid interval to one quarter note gridInterval = #(ly:make-moment 1 4) } } \new Score \with { \consists "Grid_line_span_engraver" % this moves them to the right half a staff space \override NoteColumn #'X-offset = #-0.5 } \new ChoirStaff << \new Staff { \relative c'' { \stemUp c'4. d8 e8 f g4 } } \new Staff { \relative c { % this moves them up one staff space from the default position \override Score.GridLine #'extra-offset = #'(0.0 . 1.0) \stemDown \clef bass \once \override Score.GridLine #'thickness = #5.0 c4 \once \override Score.GridLine #'thickness = #1.0 g' \once \override Score.GridLine #'thickness = #3.0 f \once \override Score.GridLine #'thickness = #5.0 e } } >>
