16.3 Graphical notation

Rhythmic items may be continued by a duration line, which gets represented by a DurationLine grob. Possible styles are 'beam, 'line, 'dashed-line, 'dotted-line, 'zigzag, 'trill and 'none. The duration line may end with a hook (beam-style only) or an arrow.

\layout {
  \context {
    \Voice
    \consists Duration_line_engraver
    \omit Stem
    \omit Flag
    \omit Beam
    \override NoteHead.duration-log = 2
  }
}

  \once \override DurationLine.style = #'line
  a'1\- s2 r
  \once \override DurationLine.style = #'dashed-line
  \once \override DurationLine.dash-period = 2
  a'1\- s2 r
  \once \override DurationLine.style = #'dotted-line
  \once \override DurationLine.dash-period = 1
  \once \override DurationLine.bound-details.right.padding = 1
  a'1\- s2 r
  \once \override DurationLine.thickness = 2
  \once \override DurationLine.style = #'zigzag
  a'1\- s2 r
  \once \override DurationLine.style = #'trill

  \once \override DurationLine.bound-details.right.end-style = #'arrow
  a'1\- s2 r

  a'1\- s2 r
  \override DurationLine.details.hook-direction = #DOWN
  a'1\- s2 r

}

DurationLine may avoid mid-line items from BreakAlignGroup.
