With one title page, you can get the first page of music to be page #1
using:

\paper {

Well, now that I tried another example with 5 notes that method didn't
work. The solution was to use \override NoteColumn.X-offset. It is a bit
strange that there is no method (that I know of) to write centralized
notes, since it is a relatively common thing in 18th century engravings.
See, for instance this engraving of Beethoven's String Quartet N. 1
attached.

music = \relative {
\override NoteColumn.X-offset = #'8.3
  c'2 d e f g
}

\score {
\new Staff {
  \time 5/2
  \clef "baritone^8" \music
}
  \layout{
\context {
  \Score
  \omit Clef
  \omit ClefModifier
  \omit Stem
  \omit TimeSignature
  \omit BarLine
  \override StaffSymbol.line-positions = #'(-2 0)

ragged-last = ##f

That helps, yes. It's not optimal, since I have to judge the
"centralization" by eye, but at least I can get a satisfactory output.
I also didn't know about \omit yet. Nice!

Cat discussions never get old...
We’ve 4 cats in our (very big) house; they pee everywhere :(
We had problems with mice and rats while there was only the old tomcat. Then we 
called an exterminator and got three young female cats (who harass the tomcat). 
At least two of them are hunting, one is too stupid... But there are still some 
rodents in the ceiling in the older part of the house.

Well, for once, If I don't use custom fields I don't have to retype the
title of the piece (once for the cover and again for the actual header of
the score). This avoids spelling mistakes, etc. But I believe I tried
something like \fromproperty before and got some other errors too. I need
to test this a little bit further to see If I can recreate the problem.
Right now I can't do it, but I'll get back on that later.

Hi Simon,

This is why my ScoreMarks line looks like this:

\consists "Axis_group_engraver"
\override VerticalAxisGroup.staff-affinity = #DOWN

\consists "Text_spanner_engraver"

Perhaps there's a better way of solving the problem, but this one works for me.

Why not use custom header fields?

  \header {
cover-title = "MY COVER TITLE"
title = "My Regular Title"
  }

and then reference \fromproperty #'header:cover-title (etc.) as needed?

Hope this helps!

There is no such thing as a "properly fed" cat.  Not if you ask the cat.
There is also quite a difference in approach: the male cat really starts
getting more enthusiastic once its prey is dead and playing football
with the corpse for hours until eating it is no longer a viable option.
The female one plays until its prey is dead, then gulfs it down.  All of
it.  Except possibly the stomach.  Ugh.

So one can't really generalize regarding the sports approach.

Well, I can attest to that.  Probably wasn't helpful that the previous
cat was house-broken to a degree that it always came back _in_ for its
cat box.  Though once the horrible, horrible kittens were roaming the
premises, he did no longer venture outside at all.

First time the female kitten paraded before the patio door, the big cat
easily three times its size panicked and did a running start like from a
Warner Bro's cartoon with wild sliding on the spot, hitting several
table legs like a pinball game ball, then rushing up the staircase and
ducking down at its top, peeking down trembling.

Pathetic.  The roommate moved in with her boyfriend who has an old
tomcat and several dogs.  Apparently now her cat is dominating over the
whole household and feared by cat and dogs alike.  But at our place, it
was completely hopeless.

MetronomeMark.break-align-symbols not heeded in custom context

[Simon Albrecht]

Hi Peter, hello bug-list,

I distilled the example some more:

%
\version "2.19.80"

\layout {
  \context {
    \name "MarkLine"
    \type "Engraver_group"
    \consists Output_property_engraver
    \consists Axis_group_engraver
    \consists Metronome_mark_engraver
    \override MetronomeMark.break-align-symbols = #'(time-signature)
    \override VerticalAxisGroup.staff-staff-spacing =
    #'((basic-distance . 0)
   (minimum-distance . 0)
   (padding . 1)
   (stretchability . 3))
    \override MetronomeMark.font-shape = #'italic
  }
  \context {
    \Score
    \accepts MarkLine
    %\override MetronomeMark.break-align-symbols = #'()
  }
}

global = \tempo "Largo"

<<
  \new MarkLine \global
  \new Staff << \global { 1 } >>
>>
%
(output attached)

The tempo mark in MarkLine behaves like one in Staff with no 
break-align-symbols (uncomment the override to test). I think they 
should both be aligned to the time signature.
As a perhaps unrelated side note: With that override uncommented, the 
vertical order of the marks is flipped.

Re: Front pages

[Caio Barros]

Hey Mark,

Is there a way of adding a front page with graphics, title etc to a
> Lilypond book, with the numbering starting at 1 on the first other
> book page?



I'm not sure what exactly you want to accomplish here. Where do you want
the numbering to appear? Is your question also about how to create a title
page?

Maybe my approach to that problem can help you. What I normally do is to
create a "cover.ly" file with all the elements I need (title, composer,
graphics, etc.), and then, in a separate file, I organize the music inside
\bookpart blocks. This avoids that lilypond prints the default  header, but
requires a bit caution. For instance:

 cover.ly

\version "2.19.46"

\paper {
bookTitleMarkup = ""
scoreTitleMarkup = ""
  }

 \markup  {
  \vspace #20
  \fill-line {
\fontsize #12 \title }
}

\markup  {
  \vspace #2
  \fill-line {
\fontsize #5 \instrument }
}

\markup  {
  \vspace #5
  \fill-line {
\fontsize #8 \composer }
}

\markup {
  \vspace #3
  \fill-line {
\fontsize #6 \poet }
}

\markup  {
  \vspace #5
  \fill-line {
\fontsize #2 \italic \dedication }
}

\markup {
  \vspace #4
  \fill-line {
\fontsize #4 \date }
}

\pageBreak

 mainfile.ly

\version "2.19.46"

%% Notice we have to add the header elements as variables

title = "My piece"
subtitle = "it has a cover page!"
composer = "Me"
date = "2018"
dedication = "To Mr. Someone"
instrument = "Piano"
poet = ""

\header {
  %% and now we just call the variables we just created
  title = \title
  subtitle = \subtitle
  composer = \composer
  date = \date
  dedication = \dedication
  instrument = \instrument
  arranger = ""
}

\bookpart {
  %\include "cover.ly"
  %{  \markup {}
  \pageBreak
  \paper {
print-page-number = ##f
oddHeaderMarkup = ##f
evenHeaderMarkup = ##f
bookTitleMarkup = ""
scoreTitleMarkup = ""
  %}
}

\paper {
  first-page-number = #0 %this avoids counting the cover as page 1
  #(include-special-characters)
  bottom-margin = 1.5\cm
}

\bookpart {
  \paper {
oddHeaderMarkup = \markup {
  \fill-line {
\on-the-fly \not-part-first-page
\fill-line { \fromproperty #'page:page-number-string \null }

Horizontally centered notes

[Caio Barros]

Hi,

I'm writing some music snippets for a friend that is creating a music text
book, and they want to have and example in which a single musical line
shows three notes: one below the line, one on the line and one above it.

I managed to write almost what they want, except that would be nicer that
the notes were horizontally centered. Lilypond automatically engraves notes
a little bit to the left so that notes more or less reflect their duration,
and I'm having trouble finding a way to override that to have the desired
output:

music = \relative {
 e'2 f g
}

\score{
\new Staff {
\time 3/2
\clef "baritone^8" \music
}

\layout{
\context {
  \Score
  \override Clef.stencil = ##f
  \override ClefModifier.stencil = ##f
  \override Stem.stencil = ##f
  \override TimeSignature.stencil = ##f
  \override BarLine.stencil = ##f
  \override StaffSymbol.line-positions = #'(0)
}
ragged-last = ##f
}
}

I tried proportional notation overrides and even found that multimeasure
rests (which are engraved in the center of the measure) have an attribute
called spacing-pair, so calling \override MultiMeasureRest.spacing-pair =
#'(staff-bar . staff-bar) for instance would align them to the center of
the measure ignoring clefs, time signatures and so on... but this property
is no applicable to note heads...

Any help?

That seems like a bug to me – I think the MetronomeMark should be 
aligned the same no matter whether it’s in a context of its own or not. 
I suspect it’s also possible to override to which grob it is aligned, 
but those overrides are complicated… can’t look it up right now.

Can you give a minimal example?

Yes. You can use bookparts to manage this inside Lilypond.

If you're willing to use more than Lilypond, there are several excellent 
options. I personally use a LaTeX template, which imports the Lilypond 
books/scores where appropriate — this gives me excellent typesetting (much 
better than Lilypond offers), while still letting Lilypond do her wonderful 
thing on the music engraving. But that kind of thing may be too much for your 
needs.

Hope this helps!

I don't intend to diff PDFs. But if I go into the lilypond source, I'm
able to see the differences between one edition an the other. Take
this as a simple example:

Cats are a natural rodent deterrent, even if they're not actively 
hunting. Mice can smell urinary proteins secreted by cats, snakes and 
other predators. According to a 2010 study at the Scripps Research 
Institute, mice don't recognize predators because of experiences with 
them but because they have evolved to do so. The mere scent of the 
urinary proteins found in cats triggers a fear response in mice.

Need to be live traps because of the lady of the house, and constantly
baiting them and driving the prisoners off to the other side of the
canal gets old.  Also doesn't put much of a dent in the population.  And
live traps for rats are hopeless.  You capture about three rats per trap
type.  Then they merrily run around the trap, somehow manage to fish out
the bait from top or side, or blockade the mechanism with rocks and/or
debris.  First generation rat poison (in order to at least keep the
kitchen free from nightly visitors) doesn't faze them all that much.  I
think we handed more than three packages in our kitchen (at least the
nightly treat kept them from foraging too much elsewhere) before we gave
up on that.  Which is ugly because with that stuff at least secondary
poisoning (namely birds of prey or cats descending on the victims) is
not much of an issue as the stuff is metabolized within a few days.

At any rate, it should be clear that I know much more than I'd really
want to about this issue.  Our cats are at best so-so for rats, but they
definitely are without much of an alternative concerning the mouse
density.  We didn't get them lightly, particularly so since cats are
territorial and we already had the useless cat in the accordion video.

Well, it's gotten easier since your earlier computing days and more
discoverable.  XEmacs, the GUI and user friendly fork, is essentially
dead since it hasn't kept up.

When a snail goes on for 40 years, it might outrun a lot of sprinters.
I'm not saying that I expect you to know Emacs.  I am just saying that
you are in a better position trying to work with it than others are, and
this decade is a greater decade to do so than the previous were.

That's all.  And even used solely as a LilyPond document reader, it's
great.

I've compared your solution with Hwaen Ch'uqi's and they give slightly
different results on the page. As you sent it, the tempo and mark
indications are raised too far above the stave  - by adjusting the
staff-staff spacing I've mended that. But the Largo metronome mark is too
far to the right as it seems to be aligned to the first silent note rather
than the clef or time signature. When the music changes tempo without
anything else, as in the Presto it's in the right place. So you now have to
override the X-offset by a variable amount depending on exactly what is in
the lower stave at that point, which will give difficulties if there's a
line break as well. Compare these, where the vertical placement of your
extra staff has been adjusted.

 

 

And here I've done a global override of the X-offset, and now the Presto is
too far to the left.
 

So there doesn't seem to be a simple solution to the issue which is
aesthetically pleasing.

All the best,

Peter

It's a whole lot nicer to read in Info format with Emacs as Info reader.
LilyPond's docs are actually the only Info files I know that make
extensive use of inline images.  At least the GNOME help reader (which
purports to deal with Info and images as well) did not scale and just
went dead when throwing the LilyPond Info files with images at it.  But
Emacs deals really swimmingly with it.

Fair enough, but my brain takes things up rather slower than it did when I
was learning computing (which included LISP) in the 1960s. Curiosity, yes,
but I find the Internals Reference manual rather heavy going. With all the
cross-references, you really need either a book (expensive to print it out!)

I can imagine.  We got the two cats on duty (the one on the video never
dared move more than 2m from the house and thus was no help) when they
were about three or four months old I think.  They were locked in one
stable cell for a few days, and then overnight for a few days longer.

Already when the cats were confined to one stable cell, the difference
was staggering.  When they roamed freely, it was overwhelming.  They

the visibility of the rodents dropped by wagonloads.  And ultimately
likely also their number, probably more because they did not dare come
looking for food than through actual killings.

Look, I'm glad that I manage dozens of views for some of the music
videos I create, some even with more "Like" than "Dislike" ratings (in

that videos like  would be much more

Cats are very effective in that; Alexander Selkirk couldn't sleep, tormented by

It turns out that with setting up all the recording stuff I'd usually
end up around feeding time of this cat (the roommate it belongs to has
moved out by now, and the cats we now have for sake of pest control have
regular working hours during which they are not to enter the house).

I tried keeping the door to the recording room closed, but then it would
scratch at the door and make more of a ruckus than when it could just
wander in and see there was nothing to be had.

Frankly, given the faces I make on those kind of recordings, the
