### 5.4.4 Staff symbol properties

The vertical position of staff lines and the number of staff lines can be defined at the same time. As the following example shows, note positions are not influenced by the staff line positions.

Note: The `'line-positions` property overrides the `'line-count` property. The number of staff lines is implicitly defined by the number of elements in the list of values for `'line-positions`.

>     \new Staff \with {
>       \override StaffSymbol.line-positions = #'(7 3 0 -4 -6 -7)
>     }
>     { a4 e' f b | d1 }

The width of a staff can be modified. The units are staff spaces. The spacing of objects inside the staff is not affected by this setting.

>     \new Staff \with {
>       \override StaffSymbol.width = #23
>     }
>     { a4 e' f b | d1 }
