Re: Acciaccatura Inside Arpeggio

[Neil Puttock]

Hi Ted,

Here's one way of doing it, using a hidden grace note:

\version "2.11.42"
\paper { ragged-right = ##t }
\score {
        \new Staff \relative c'' {
                %a note to improve layout for this snippet
                g
                %polyphonic section
                << {
                        %the acciaccatura, with slur to g
                        \acciaccatura a8\arpeggio
                        %override to ignore "note clashing column" error
                        \once \override NoteColumn #'ignore-collision = ##t
                        %to prevent slur joining b have to remove d & b
                        g8.
                }
                %a new voice for the hidden grace note
                \new Voice { \voiceTwo
                        %an invisible gracenote with arpeggio to join up with 
the acciaccatura above
                        \hideNotes \grace a,8\arpeggio
                        %the rest of the chord. By scaling a dotted crotchet, 
saves having
to remove stencil for flag
                        %cf. \oneVoice \once \override Stem #'flag-style = 
#'no-flag <b d>8.
                        \unHideNotes \oneVoice <b d>4.*1/2
                } >> f'16
        }
        \layout {
                \context {
                        %allow arpeggios to be connected between different 
voices on a stave
                        \Staff
                        \consists Span_arpeggio_engraver
                        connectArpeggios = ##t
                }
        }
}

If it's OK for the slur to be above, it's a bit simpler:

\version "2.11.42"
\paper { ragged-right = ##t }
\score {
        \new Staff \relative c'' {
                g
                << {
                        \slurUp
                        \acciaccatura a8\arpeggio
                        <g d b>8.
                }
                \new Voice { \voiceTwo
                        \hideNotes \grace a,8\arpeggio
                } >> f'16
        }
        \layout {
                \context {
                        \Staff
                        \consists Span_arpeggio_engraver
                        connectArpeggios = ##t
                }
        }
}

Regards,
Neil
