Hello,

while developing a workaround (or solution?) for issue 4316 
, I 
encountered the following problem: \offset cannot be used on X and Y 
offset properties, apparently because these are mutable, and as the doc 
string for (offsetter) in scm/music-functions.scm states, \offset is 
limited to work only on immutable properties. (I haven’t really gotten 
behind the distinction of mutable/immutable properties…)
Now, I don’t really know how to circumvent this, and it seems like a 
really important usecase for \offset. Do you have any ideas here?


For more context, see issue 4316 and the current version of the \off 
function I’m developing (attached; I hope it’s readable by the comments 
I gave).


TIA,
Simon
\version "2.19.23"

The LilyPond command you want is very straightforward: \omit KeySignature.
I attach an example which also features a parallel music expression

Actually, you need Staff.KeySignature, because the KeySignature lives in 
Staff, not in Voice (as Bottom context).

I hate it, but actually, it is very normal!

Mostly in Brass Band march parts, but pretty much any part from the
first half of last century (and I play a few!) only display the key
signature when it changes.

Re: Two-Syllable Beam with Sharp and Slur

Say, you all are very friendly! I didn't expect such
enthusiastic help!
I started asking questions on Music Stack Exchange and they
were giving me such a hard time that I was getting a bit
discouraged.

http://music.stackexchange.com/questions/34199/lilypond-incorrectly-displaying-natural-signs-in-b-major/34206#34206

I am a regular user of Gregorio, and I know Gregorian Chant
pretty well, but I am learning music theory for modern
nation as I go. At the moment I am creating a childrens'
hymnal for Eucharistic Crusaders - I have an old booklet
hand-written by nuns and am using Frescobaldi with Lilypond
to typeset everything. I'm not completely new to modern
notation, but I never learned it as a child (we didn't study
that in the hills where I'm from).

So as I proceed with this little booklet, I'm sure to have
other questions that I can't resolve by googling or
searching the docs. I will be pleased to use the list!
Thanks for being so nice!

Align instrumentName baseline (?) to Lyrics baseline

2015-07-21 Thread RomanticStrings

How might I ensure that the bottom of a columned instrumentName aligns to the
bottom of the Lyrics in a score?

I am trying to imitate chant notation with the initial capital and mode in a
centered column, but I don't know how to make sure that the bottom of the
"A" lines up with the bottom of the "L" under the music.  Is there a
different way to approach this than with instrumentName?

Since you provided the link to show us the hard time you've had on Stack
Exchange: I beg to differ. You were entering all-natural notes but
provided a key signature of b-major. Then you asked on SE why almost all
notes have natural signs in front of them.

What the folk on SE did was (1) helping you - like asking if you meant
gis instead of g, or if the piece really was in Bb or indeed C - and (2)
telling you that any music engraving software is just a tool which you
will only be able to use properly if you understand (at least roughly)
what you're doing. Which your answers on SE indicate you did not, if I
may be so bold.

So, while you should not get discouraged, you should nevertheless be
open to suggestions and criticism. This mailing list is full of
extraordinarily helpful and nice people, that's for sure, but the SE
guys were rather helpful as well. All they did in addition was
suggesting to become more familiar with musical theory, notation, and
indeed the stuff you were actually trying to transcribe.

After the first note or measure, so it affects all but the first key

You have to do nothing. Laying out one’s LilyPond files can be a quite 
personal decision on what you like best; I was merely proposing a way 
which proves to be robust for larger and more complicated setups also.


In general, I’d suggest the Learning Manual as a must-read gentle

Problem with merging notes and accidental placement in two voices

Greetings -

(This is the second time - my original .png was too large.)

I'm running LilyPond 18.2 under Win7.

I'm attaching 3 files:
1) NoteMergeAndAccidentals.ly   :   LilyPond source file with no tweaks
2) NoteMergeAndAccidentals.pdf   :  a PDF of NoteMergeAndAccidentals.ly
3)NoteMergeAndAccidentalsOriginal.png   :   what I'm trying to replicate.

I'm having problems with some music in two vioces. I can "un-merge" the
first two notes in the accompanying .ly file, but I can't seem to un-merge
the accidentals. I'm also unable to get separate the a-flat and a-natural
and get their accidentals next to the notes.

I would appreciate any help with these issues.

Thanks for your time and attention,

The GIMP can export to jpg and png; in the export window you can change 
the compression level or quality – higher compression means lower 
quality but also smaller files. How much the file size changes and which 
image format is better (in quality, file size, …) depends on the image 
content.

Okay, well, I have actually read the learning manual, just

If I place \omit Staff.KeySignature anywhere significant, it

You have to insert the \omit commands not in the first bar but later. 
The following code hopefully does what you want. Explanation: I used a 
spacer rest (s1) in global. Because this would move not only the \omits 
but also the beginning of the melody, I moved the \global from the 
beginning of the melody to the \new Staff, where melody and global are 
now simultaneous.

The issue of mutable properties is actually only a problem with
Hairpin.X-offset in your example.  You'll note that each of the other
properties you offset has a default value in scm/define-grobs.scm to
calculate a displacement against.

The problem with these other properties is that "unpure-pure containers"
are involved, and the current implementation of \offset has no provision
for dealing with this situation.  If it could, a number of use cases would
be opened up--some very handy ones at that.

It is straightforward to redefine \offset to extract the unpure component
in such cases and use that to offset against.  (See attached.)  I haven't
noticed any problems, but I do wonder if a problem might occur, say, if the
change to the property should properly result in a different line break.

Now, whether it would be feasible to offset against mutable properties I'm
not sure.  I've never had success getting changes to values stored there to
have any effect on output.  Too late in the game?

Hope this helps,
David

Re: lilypond-user Digest, Vol 152, Issue 74


Malte,

Okay, that does work for suppressing the key signatures in 
the latter staves, but I start my melody with a \partial 8 
and the spacer throws off the count.


So I took that line:
\omit Staff.KeySignature

and threw it in after the leading note in the melody and it 
worked!


As it turns out, that's all I had to do in the first place.
Let the signature print the first time and *then* disable it.

Thanks!

Spacer rests can be made of arbitrary length, so s8 instead of s1 would 
do the trick too ;) But your solution is easier, why didn’t I think of that?

Re: Attachment size

2015-07-21 Thread tisimst

You are probably doing this already, but in GIMP, go to "Image" > "Scale
Image" and change the Width/Height units to "Percent" and change it to
something smaller than 100% and hit "Scale". This should reduce the size of
the image nicely.

For reference, though, when saving to an image format, remember that JPG
will almost always be MUCH SMALLER than PNG (unfortunately), sometimes 2-3x
smaller in size because it is a compressed, lossy format. PNG can also do
compression, but mostly it doesn't compare in file size to JPG. Same with
JPG being smaller than PDF (usually).

Forgive the noise if you've already tried this and knew that about image
types, but that's what I would do.

Thanks to all of you who responded to my query. I ended up not using Gimp
at all. I was able (after some hardware changes) to scan, then crop, the
page that was giving me the problem, and the end product came out quite
small.

Thanks again,

Re: Align instrumentName baseline (?) to Lyrics baseline

2015-07-21 Thread Klaus Blum

Hi Conor, 

not the most beautiful hack, but maybe it helps: Instead of instrumentName,
use a stanza object: 

% -

\version "2.19.21"

stemOff = { \hide Staff.Stem }

\score {
  <<
\new Staff
\relative c' {
  \stemOff
  \dynamicUp
  \cadenzaOn
  f4
}
\addlyrics {
  \set stanza =
  \markup {
\normal-text
\with-dimensions #'(0 . 0) #'(0 . 0)
\translate #'(-8 . 0)
\override #`(direction . ,UP)
\fontsize #1.5  % for the letter "V", maybe needs to be adjusted as
stanza numbers use a smaller font size
\dir-column {
  \abs-fontsize #36
  \center-align
  A
  \vspace #0.5
  \center-align
  V
}
  }
  L
}
  >>
  \layout {
\context {
  \Staff
  \remove "Time_signature_engraver"
}
ragged-right = ##t
  }
}

% -

Cheers, 
Klaus

No, the Y-offset callback will return the same values whether
outside-staff-priority is its usual value or ##f.  \offset takes the result
of this Y-offset callback and offsets against it.

This is probably not what you want, but there's a tricky way to offset
against a user value, involving a combination of override and tweak:

 \relative {
  \hideNotes
  \dynamicUp
  \override DynamicLineSpanner.outside-staff-priority = ##f
  \override DynamicLineSpanner.Y-offset = 0 % try other values
  b'2
  -\offset DynamicLineSpanner.Y-offset 2
  \< 2\f\>
  2 2\f\<
  2\f
}

Here, of course, we could simply do the following :)

\relative {
  \hideNotes
  \dynamicUp
  \override DynamicLineSpanner.outside-staff-priority = ##f
  \override DynamicLineSpanner.Y-offset = 2
  b'2\< 2\f\>
  2 2\f\<
  2\f
}

My understanding is that immutable properties store default values--such as
a procedure to be applied when calculating Stem.thickness or whatever, and
immutable properties store the results of calculations for a particular
instance of a grob--for example, the value obtained by applying the default
procedure to a certain Stem.

These terms are defined here (a bit cryptically I think):

But they are--for example,
http://lilypond.org/doc/v2.19/Documentation/internals/dynamiclinespanner is
built from the entry in scm/define-grobs.scm.
