6.4.7 System start delimiters

Many scores consist of more than one staff. These staves can be joined in four different ways

• The group is started with a brace at the left, and bar lines are connected. This is done with the GrandStaff context.

            
            \new GrandStaff
            \relative <<
              \new Staff { c1 c }
              \new Staff { c c }
            >>
       

  

• The group is started with a bracket, and bar lines are connected. This is done with the StaffGroup context

            
            \new StaffGroup
            \relative <<
              \new Staff { c1 c }
              \new Staff { c c }
            >>
       

  

• The group is started with a bracket, but bar lines are not connected. This is done with the ChoirStaff context.

            
            \new ChoirStaff
            \relative <<
              \new Staff { c1 c }
              \new Staff { c c }
            >>
       

  

• The group is started with a vertical line. Bar lines are not connected. This is the default for the score.

            
            \relative <<
              \new Staff { c1 c }
              \new Staff { c c }
            >>

The bar lines at the start of each system are SystemStartBar, SystemStartBrace, and SystemStartBracket. Only one of these types is created in every context, and that type is determined by the property systemStartDelimiter.

Commonly tweaked properties

System start delimiters may be deeply nested,

     
     \new StaffGroup
     \relative <<
       \set StaffGroup.systemStartDelimiterHierarchy
         = #'(SystemStartSquare (SystemStartBracket a (SystemStartSquare b)) d)
       \new Staff { c1 }
       \new Staff { c1 }
       \new Staff { c1 }
       \new Staff { c1 }
       \new Staff { c1 }
     >>
