Re: formatting meterless music

[Kevin Barry]

Hi Michael,

I have a few suggestions based on my own experience, but there are probably a few ways to approach the problem.

I would recommend that you create a global variable for controlling the timing in the piece. It need only contain spacer rests, and potential line breaks (marked by \bar "", which will tell LilyPond that a line break is possible here with \cadenzaOn). You should identify _all_ the possible places LilyPond might break your piece up into lines (and then it will pick the best ones). At a glance it's not really clear to me what would work for your piece but I made an example just to show what I mean.

About bar lines: if you remove the engraver then you will not be able to add bar lines at the end. Although I'm not sure why you need this (since the cadenza mode doesn't print them) what I imagine you should do is simply remove the stencil at the beginning with \override Staff.BarLine.stencil = ##f, and then at the end when you need a double bar just revert the override with \revert Staff.BarLine.stencil.

Here is your code with my additions (including the very long lines, which is how it pasted into my editor):

\version "2.18.2"

%% This variable controls the timing and line breaks

global = {

  \override Staff.TimeSignature.stencil = ##f

  \cadenzaOn

  % \bar "" will tell LilyPond that it's acceptable to break the line at a given point

  s2. \bar "" s4 \bar "" s2. \bar "" s \bar "" s4 \bar "" s2. \bar "" s \bar "" s4 \bar "" s2. \bar "" s \bar "" s4 \bar "" s2. \bar ""

}

  

\header {

  title = "Oremus"

  tagline = ""

}

\new GregorianTranscriptionStaff 

\with { 

  \remove "Time_signature_engraver"

}

{ 

  aeh'4 bes' c'' deh'' ees'' f'' geh'' 

}

voiceA = {

  \clef treble

  \cadenzaOn

  \accidentalStyle dodecaphonic

  <c'' ees'''>2. <geh' f'''>4 <deh' bes''>2. <f' aeh''>2. <c'' deh'''>4 <geh' ees'''>2. <aeh c'''>2. <bes f''>4 <ees' geh''>2. <deh' aeh''>2. <c' f'''>4 <geh' bes''>2. \bar "|."

}

voiceB = {

  \clef bass

  \cadenzaOn

  \accidentalStyle dodecaphonic

  deh,8[ deh,8] ees,4 geh,8[ deh,8 bes,8] ees,4 geh,8[ geh,8 c,8] ees,4 geh,8[ f,8 bes,8] r4 r16 deh,8[ deh,8 deh,8] ees,4 deh,8[ bes,8 f,8 geh,8] ees,4 deh,8[ geh,8 geh,8 aeh,8 deh,8 geh,8] r4 r16 deh,8[ deh,8] ees,4 geh,8[ deh,8 bes,8] ees,4 geh,8[ geh,8 c,8] ees,4 geh,8[ f,8 bes,8] \bar "|."

Michael,

You cane use \cadenzaOn  and then group your eighth notes with [ ] e.g.   deh,8[ deh,8] ees,4 geh,8[ deh,8 bes,8] ees,4 geh,8[ geh,8 c,8]

That should cause everything to work they way you are after and don't bother to declare a time signature. 

best of luck,

Shane

Hello,

I'm working on a piece without barlines or a time signature.  The file is attached below.  I have tried using the \cadenzaOn command, but this seems to produce nice output only when I use a simple time signature (4/4) and manually bar (|) the input.  Unfortunately, the rhythmic values I'm using do not lend themselves to this approach.  The introduction of a couple 16th notes shifts everything over and makes it impossible to divide things into neat 4/4 bars.

My current solution modifies the layout's context block to completely suppress barlines and time signatures.  However, since lilypond still thinks I'm in 4/4, I'm getting ties across invisible barlines.  Also, since all barlines are suppressed, I can't get a double bar line at the end.  Is there any way around these problems?  Is there a way to produce meterless music without the ghostly ties that still includes a double barline at the end?
