Problems with lyrics of a gregorian chant piece

[David Gippner]

Hello folks,

I've got some problems with the lyrics of an gregorian chant piece. The
text doesn't fit under the notes correctly. What have I done wrong or
what can I do to correct it?

The piece follows here:

\version "2.11.20"
\include "gregorian-init.ly"
\include "deutsch.ly"
\score {
<<
\new VaticanaVoice = "cantus" {
a a a a a \melisma\[ a \pes h \]\melismaEnd a a a a g \melisma\[ g \pes
a \]\melismaEnd a \finalis \bar " "\break
a a a a a \melisma\[ a \pes h \]\melismaEnd a a a a g \melisma\[ g \pes
a \]\melismaEnd a \finalis \bar " "\break
}
\new Lyrics \lyricsto "cantus" {
E -- us, in ad -- ju -- to -- ri -- um me -- um in -- ten -- de. Do --
mi -- ne, ad
ad -- iu -- van -- dum me fes -- ti -- na.
}

Yours sincerely,
