Voici ce que je peux proposer :
csBracket = \override PianoStaff.Arpeggio #'stencil = #ly:arpeggio::brew-chord-bracket
\new PianoStaff
\with { connectArpeggios = ##t }
<<
\new Staff
{
<< \relative c'{
\key c \major
e'8 d4-4 c8^~ c8 b16
\once\override Score.Arpeggio.direction =#right
\once\override Score.Arpeggio #'rotation = #'(180 0 0)
\once \override TextScript #'X-offset = #'3.0
\csBracket a\arpeggio_\markup "m.d." b8[ d-3]
} \\
\relative c'{
\key c \major
f4 e8 e8\rest e2\rest
} >>
}
\new Staff \relative c
{
\key c \major
\clef "bass"
a16 g a b
\clef "treble"
c' d e-3 f g f g \csBracket a\arpeggio f a g f
}
>>
\layout {
\context {
\Staff
\remove "Time_signature_engraver"
\remove "Bar_engraver"
}
}
