tremolo as post event

[Mike Solomon]

Hey all,

Is there any way to create a tremolo as a post event?
I’m doing an arrangement for string quartet of a vocal piece and, at certain 
moments, I’d like to use tremolos.  So, for example,

{
c2
}

would become

{
  c2:32
}

Rather than doing:

{
  \tag #’vocal { c2 } \tag #’strings { c2:32 }
}

I’d like to do:

{
  c2\trem #32
}

and then define the function \trem differently in different files so that it 
appears in one and not the other.

As a stop gap solution I’m overriding the tremolo stencil to be ##f, but 
something about that seems unsatisfactory…

Cheers,
MS

Hi Ted,

I think you should come to different point of view:
a( b c d) is as correct as a (b c d) because the starting slur is
added to the articulations of the _previous_ _note_, saying "play
legato from me".
Even:
a
(
b
c
d
)
will work.
Inputting a( b c d) is more a convention to remind oneself to this fact .

A BarCheck will only make sense after a note has been _completely_
written, i.e. including its articulation, markups, dynamics etc.
Therefore the BarCheck must be put after the starting slur.
I don't think you would expect a | -. b to work!?

An input like  a | ( b) would mean "play legato from the BarCheck"
Ofcourse nonsense and LilyPond complains.
Even the error-message:
   syntax error, unexpected EVENT_IDENTIFIER
is correct, because a BarCheck will not take any musical event.

So no issue here.

HTH,
  Harm

null post event

[Mike Solomon]

Hey all,

Is there a sort of null post event?  The following doesn’t work

foo = #(define-event-function (parser location) ())

{
  c\<-.\foo d
}

I’d like for foo to do nothing but still function as a post event.

Cheers,

Problems / questions around a choir partition

[Markus Baertschi]

I've re-set a choir partition for our men's choir in lilypond. Some
RTFM did help to solve most problems, but there are some things I
don't know how to resolve.

My problems are in no particular sequence:

- How can I set the headers ('piece') so they are close to the score
and not close to the top of the page ?
  Is there a better method to have a header at the top of a score then
'header' ?

- How can I center the second line of lyrics like the 1st line inside a repeat ?
  See bar #19 and #20 for the misaligned text. I've already tried the
'\once \override LyricText.self-alignment-X = #CENTER'
  and it changes absolutely nothing

- My partition has two parts. The first part has two lines of lyrics
and second part start out with a single lyrics line per voice.
  After trying and not finding a way to 'reset' the lyrics to a single
line, I've split it into two scores. This has worked so far, but
  now I get two distinct midi files. Are better ways to do that ?

For reference:
- The .ly file: http://pastebin.com/ppL8g160
- The pdf file: www.markus.org/download/Nous_allons_chercher_le_vent.pdf

Thanks  Markus

hairpin aesthetics

[Mike Solomon]

Hey all,

When typesetting:


\version "2.19.15"


\relative c'' {
  \time 2/4
  cis8\> ( bisis ) fis'\< ( e ) |
  d2\! |
}


the second hairpin seems really short compared to the first. My guessing is 
that whatever gap is put between the hairpins is tacked onto the start of the 
second instead of evenly distributed between the two.

Does anyone have examples from the literature with cases like this?  Is the 
second hairpin really shifted that far over?

Cheers,
MS

Yes, now this makes sense.   I got some private email as well explaining what's 
going on here.   The problem is that the open paren looks lisp-ish, and so I 
want it to be a grouping syntax, but it's really just a marker that happens to 
pair with another marker that happens to be a closing paren.   I am not in love 
with this, but I see how it happened, at least.   It would be better if the 
error message were something like "barcheck doesn't take an event," but at 
least now I understand how we got here.   Thanks to you and Pierre (and the 
private person whom I shall not name here) for walking me through this.

Build issue in Fedora due to font changes

[Jon Ciesla]

With the latest release of the UFW fonts, they've dropped the Cyrillic
glyphs due to poor quality. I see that both 2.18.x and 2.19.x still need
ufw's ru fonts, and so lilypond fails to build in rawhide.  Is there
another font set, preferably one in Fedora already, that you'd recommend or
are planning to migrate to?

The Fedora BZ for reference:
https://bugzilla.redhat.com/show_bug.cgi?id=1160132

Thanks,
Jon Ciesla, Fedora lilypond maintainer.

Re: Problems / questions around a choir partition

[tyronicus]

For your first question, I would try top-markup-spacing and
markup-system-spacing. Check out this beautiful guide by Abraham Lee (?): 
verticalspacing.pdf
  
They are flexible variables, so try #'padding.

This is a nice PDF, thanks !

I found a solution, adding \vspace #5 pushes the header down to the score,
problem solved !

\header { piece = \markup { \vspace #5 \bold "Couplets" \italic "
tempo de marche" } }

The unchanged .ly file works correctly in 2.19.15, so maybe consider
installing this version.  It's really quite reliable.

Alternatively, if you want to stay with 2.18.3, try running the two
contexts in parallel for the whole piece, using \skips to pass over the
notes which don't have alternative lyrics, like this (for the Bariton line):

\new Lyrics = "refrain2"  \lyricsto "Bariton" {
  \set stanza = "2)"
  Sur nor | monts, sur nos monts puis -- | sants, tout puis -- sants,
  l'on | n'en -- tends le vent n'en -- | tend que le vent
  l'on ne |
  voit l'on ne voit le | ciel que le ciel l'on ne |
  sent que le so -- leil Au re --
  lons cher -- cher le vent
  vent. Ouh - - -
}
\new Lyrics \lyricsto "Bariton" {
   \repeat unfold 23 \skip 1
   voir au re -- voir re -- voir au re -- voir nous all~- |
}
 
The value 23 is the number of "missing "syllables.

A similar approach may help with this too.

Yes, looks like a bug in 2.18. I've installed 2.19 and there is works.

I see, I was unaware of the \skips statement. Will try next time !
