Re: misusing arpeggios

[Mats Bengtsson]

One solution is to typeset the invisible upper and lower notes in 
separate Voice contexts and then use the connectArpeggio feature to get 
a single arpeggio over the three voices. By default, the engraver that 
handles connected arpeggios is only available in the PianoStaff 
context, so you have to add it
also to the Staff context. Also, the \arpeggioBracket macro only does 
its settings in the current Voice, not for the full Staff, which is 
where the connected arpeggios are handles. Therefore, you have some 
extra lines of code that might look a bit strange, in the following 
example:

\version "2.9.28"
\new Staff \with {\consists Span_arpeggio_engraver} \relative c''{
\set Staff.connectArpeggios = ##t
\override Staff.Arpeggio #'stencil = #ly:arpeggio::brew-chord-bracket
<< \new Voice {\hideNotes <a>\arpeggio}
\new Voice { c }
\new Voice {\hideNotes <e>\arpeggio }
> >
}
