In orchestral scores, staff lines that only have rests are usually removed. This saves some space. This style is called `French Score'. For Lyrics, ChordNames and FiguredBass, this is switched on by default. When these line of these contexts turn out empty after the line-breaking process, they are removed.
For normal staves, a specialized Staff context is
available, which does the same: staves containing nothing (or only
multi measure rests) are removed. The context definition is stored in
\RemoveEmptyStaffContext
variable. Observe how the second staff
in this example disappears in the second line
\score { \notes \relative c' << \new Staff { e4 f g a \break c1 } \new Staff { c4 d e f \break R1 } >> \paper { linewidth = 6.\cm \context { \RemoveEmptyStaffContext } } }
The first page shows all staves in full. If empty staves should be
removed from the first page too, set remove-first
to false in
RemoveEmptyVerticalGroup.
Another application is making ossia sections, i.e. alternative melodies on a separate piece of staff, with help of a Frenched staff. See input/test/ossia.ly for an example.
