Perhaps something like this can work?

modeOnD =  \context Voice = "notes" { \theNotes }
theLyrics =  \context Lyrics = "text" { \text \text }

theStaff = \context Staff = "Mode" \with { \remove "Time_signature_engraver" } 
{
  \transpose d d { \modeOnD }
  \break
  \transpose d c { \modeOnD }
}

theMusic = <<
  \theStaff
  \lyricsto "notes" \theLyrics
>>
