Re: Unwanted barline. How to get rid of it?

Merry christmas dear all Lilyponder!

Sry for my late reaction on this one - I finally got to work through
all these mails and tried the example code provided by Malte:

Interesting enough on my 2.19.33 installation there is no double count
of measure 8, as the mark in line 3 suggests (the partial bar is counted
like any other bar).

Has there been a change in behaviour somewhere along the way or ist
this a (newly introduced) bug in the current devel version ?

Kind regards,
Michael

Your 3rd full bar has only 5 quavers. It should be a partial, if that's
what you want.

Re: Unwanted barline. How to get rid of it?

[Robert Blackstone]

Hello, 

Did I notice warning: barcheck failed at: 5/8
c r4
  | ?
Yes, I did. 
Should the r4 be r4. ? 
No, I don't think so, for if there is, in this repeated section, a partial 8 at 
the beginning it is logical that the last bar of that section has one eighth 
note or rest less.
More importantly, this is what the original has, and for many reasons I want to 
stick to that.  
Maybe it's "illegal" but shouldn't be there some trick to hide my sins? 
LilyPond seems full of the most beautiful tricks.

Thanks anyway
.
Best regards,
Robert

This depends on whether you really have an upbeat (f.e. Scherzo ends 
with full measure, Trio starts with upbeat) or an "incomplete" measure 
(f.e. if you have bars of different length whithout explicitely changing 
the time signature; see last of Rachmaninov's Etudes-Tableaux). Have a 
look at the output of the following code. Three different solutions show 
three different types of behaviour (look at bar lines and bar numbers).


\version "2.18.2"

{
\override Score.BarNumber.break-visibility = #'#(#t #t #t)

b4 b b b
b b b \set Timing.measurePosition = #(ly:make-moment 4/4)
\mark "missing barline"
b b b b
\break

b b b b
	\set Timing.measureLength = #(ly:make-moment 3/4) b b b \unset 
Timing.measureLength

\mark "everything ok (if it's an 'incomplete' measure)"
b b b b
\break

b b b b
\partial 4*3
b b b
\mark "m. 8 counts twice (ok if it's really an upbeat)"
b b b b
}

I've not tried it, but would an s8 work? If you just need to pad the bar
out, that seems obvious to me.

I was just thinking that this is a different approach to what everyone
else has suggested so it might be a great curveball, or it might be
completely off key (sic) :-)

Yes, it should be a partial. 
But I do not know how to code that, 5 instead of 6 eighth notes, at the end of 
a section.

No. If you spell out the repeat you'll see it directly:

\relative c {
  \time 6/8
  \partial 8 c'8 c4. c | c c | c r4 c8 | c4. c | c c | c r4 | %% <- missing 8
  c4.~  c \bar "|."
}

Easiest fix might be:

\relative c {
  \clef bass
  \time 6/8
  \repeat volta 2 { \partial 8 c'8 c4. c | c c | c r4 }
  \set Timing.measurePosition = #(ly:make-moment 6/8)
  c4.~  c \bar "|."
}

Hi Robert,

do you mean something like this?

{
  \relative c {
\clef bass
\key c \major
\time 6/8
\partial 8
\repeat volta 2 {
  c'8
  c4. c |
  c c |
  c r4
}
r8 | c4.~  c \bar "|."
  }
}

Thank you very much. 
This is exactly what I need.

Re: Unwanted barline. How to get rid of it?

Just checked. As I said -- you may want another partial bar

   \relative c {
   \clef bass
   \key c \major
   \time 6/8

\repeat volta 2 {\partial 8
c'8
 c4. c |
 c c |
* \partial 8*5*
 c r4|
 }

 c4.~  c \bar "|."
 }

Thank you Chris. This does it.
I did not know how to code this.

Yes, that syntax is not obvious from the documentation. I have used this on
typesetting some Beethoven variations which have anacrusis bars; I needed
"\partial 16*10" in one place.

I think using a partial bar is more intuitive than "/set
Timing.measurePosition = #(ly:make-moment 6/8)". But there may be
situations where the latter is necessary.

HTH. Thanks,

Chris
