I created this minimal example :
\version "2.21.0"
\include "italiano.ly"
soprano_notes = \relative do' {
fad fad16 sold8 la16 re4 re16 re8 re16
re4 re16 dod8 si16 dod2
}
alto_notes = \relative do' {
re2 re mi2. mi4
}
tenor_notes = \relative do {
\clef "G_8"
la2 fad sol2. ( fad4 ~ fad2)
}
bass_notes = \relative do {
\clef bass
re4 dod si lad
si2 lad
}
\score {
\new ChoirStaff <<
\new Staff
<<
\new Voice = "soprano" {
\soprano_notes
}
>>
\new Staff
<<
\new Voice = "alto" {
\alto_notes
}
>>
\new Staff
<<
\new Voice = "bass" {
\bass_notes
}
>>
>>
}
And here is the result I have :
As you can see in the third stave, the 4 notes have the same duration but the spacing is incorrect (and the same kind of problem appears in the second measure). I want to have all the notes with the same duration to take the same horizontal space, is that possible?
