7.7.11 Gregorian Chant contexts

The predefined VaticanaVoiceContext and VaticanaStaffContext can be used to engrave a piece of Gregorian Chant in the style of the Editio Vaticana. These contexts initialize all relevant context properties and grob properties to proper values, so you can immediately go ahead entering the chant, as the following excerpt demonstrates

     
     \include "gregorian-init.ly"
     \score {
       <<
         \new VaticanaVoice = "cantus" {
           \[ c'\melisma c' \flexa a \]
           \[ a \flexa \deminutum g\melismaEnd \]
           f \divisioMinima
           \[ f\melisma \pes a c' c' \pes d'\melismaEnd \]
           c' \divisioMinima \break
           \[ c'\melisma c' \flexa a \]
           \[ a \flexa \deminutum g\melismaEnd \] f \divisioMinima
         }
         \new Lyrics \lyricsto "cantus" {
