Hi Joseph,
a more common approach to the situation is using a separate music
variable containing information common to all parts. E.g.
%%%%%%%%%%%%%
aux = {
\tempo 4 = 100
s1
\bar "|."
}
musicOne = { e'1 }
musicTwo = { c'1 }
\score {
<<
\new Staff <<
\new NullVoice \aux
\new Voice \musicOne
>>
\new Staff \new Voice \musicTwo
>>
\layout {}
}
\score {
\new Staff <<
\new NullVoice \aux
\new Voice \musicOne
>>
\midi {}
}
%%%%%%%%%%%%%%
