NR 3.3.2: \tagGroup

[Federico Bruni]

Hi all

If you scroll down to \tagGroup here:
http://lilypond.org/doc/v2.19/Documentation/notation/different-editions-from-one-source#using-tags

you find:

%

   \tagGroup #'(violinI violinII viola cello)

declares the respective tags as belonging to one tag group.

   \keepWithTag #'violinI …

will then only be concerned with tags from violinI’s tag group: any 
element of the included music that is tagged with one or more of tags 
from this set but not with violinI will get removed.


To any \keepWithTag command, only tags from the tag groups of the tags 
given in the command are visible.


%

I don't understand what this command does actually.
The last sentence is a bit confusing and there's no clear example 
showing the expected behaviour.


James, if it turns to be a documentation bug please hold on until 
Friday when I hope I've finished my translation (and review) of this 
chapter.


In the following example commenting/uncommenting \tagGroup does not 
change any behaviour.

What I'm missing?


\version "2.19.31"

music = \relative c'' {
 %\tagGroup #'(A B C D)
 \tag #'A { a4 a a a }
 \tag #'B { b4 b b b }
 \tag #'C { c4 c c c }
 \tag #'D { d4 d d d }
}

\new Staff {
 \keepWithTag #'A
 \music
}

Correct.  If you replace the rather generic names A, B, C, D, E with
something more specific like Urtext, EditionBrauer, EditionThoeni,
Layout, Midi, then it becomes more obvious that it's a nuisance if

\keepWithTag #'Urtext

will remove every music tagged with Midi or Layout.  Forming two
separate tag groups will cure that problem.

Re: Introducing "LilyPond HTML Live Score"

[Mathieu Demange]

Hi David,

I just updated the project's repository. I refactored and simplified a
lot of things.

There's now a single python script (make-live-score) which takes care of
everything. Also, you don't need to edit your .ly file anymore.

Please note that the script except audio files to be specified (at least
one format) or it'll break the js part. This'll be fixed in the next
release and will allow to have visual rhythmic feedback even with no
sound played back.

See the README.md file for details (and command usage, it has been
reworked).

Please tell me how it goes now.

Cheers,

Mathieu

Instrument names disappear when using \partcombine and grace notes.

[thorne]

Hi.  With the following example, the instrument name doesn't appear on
the rendered pdf on the second staff (the one that uses \partcombine).
I suspect it has something to do with the use of \grace in the notes,
because when I remove the grace notes the effect disappears.

I have done \grace {s16} in all the parts that don't have the grace
notes, because I have read that it is necessary when you are beginning
with a grace note or changing clefs. (The actual score I am working on
begins with a grace note in one instrument as here.

Am I doing something wrong?




\version "2.19.3"

catOne = {\grace {b'16} a'2 d'}
catTwo = {\grace {s16} c'2 b}
dogOne = {\grace {s16} a'2 b'}
dogTwo = {\grace {s16} c'2 d'}

\score {
  <<
\new Staff = "cats" {
  \set Staff.instrumentName = #"2 Cats"
   << \catOne \\ \catTwo >>
}

\new Staff = "dogs" {
  \set Staff.instrumentName = #"2 Dogs"
   \partcombine \dogOne \dogTwo
}
  >>
}

Can't confirm with 2.19.32
Though, in general it's issue 34
https://sourceforge.net/p/testlilyissues/issues/34/
At least related.

Try:

\version "2.19.3"

catOne = {\grace {b'16} a'2 d'}
catTwo = {\grace {s16} c'2 b}
dogOne = {\grace {s16} a'2 b'}
dogTwo = {\grace {s16} c'2 d'}

\score {
  <<
\new Staff = "cats"
\with { instrumentName = #"2 Cats" }
{
   << \catOne \\ \catTwo >>
}

\new Staff = "dogs"
\with { instrumentName = #"2 Dogs" }
{
   \partcombine \dogOne \dogTwo
}
  >>
}

IMHO, we should really get rid of advertising \set
Staff.instrumentName = ... and go for \with { instrumentName = ... }
everywhere.

Do you have lilypond code printed at paper that you want to scan?

Sure.  The syntax was

  \override Fingering #'side-axis = #Y

in 2.16.

No.  The TabStaff tells me what fret to use on what string.  It does not

Re: accidentals for just intonation

[ciconia]

Young has pieces with primes in the upper 300s.

How does Partch notate his music? If I remember correctly he does put ratios
over his notes, but I'm not sure how it works. As for La Monte Young - I
don't think any of his music that *is* notated uses any form of conventional
notation. Please correct me if I'm wrong.

A new problem. I'm able to successfully run the script on both your
example and my test file. But now whenever I open it up in a browser
(Firefox, Chrome, Rekonq) I get the message that I need to update my
Flash player. I'm running Kubuntu 15.10 and everything is up-to-date
but still no go.

The example you linked to at the head of this thread still works.

Hi David,

Can you send me the generated HTML output file ? If you see such a 
message, this means that the JavaScript code contains errors. I'll fix 
that if I can see your file.

There's now a single python script (make-live-score) which takes care

Please note that the script except audio files to be specified (at 
least

one format) or it'll break the js part. This'll be fixed in the next
release and will allow to have visual rhythmic feedback even with no
sound played back.

See the README.md file for details (and command usage, it has been

Please tell me how it goes now.

Hey Mathieu,

So here is my Lilypond test file.

I then convert that to an ogg file with Timidity:

it's been abandoned.

Ok, I switched to a score that uses only one page.

I changed line 80 to reflect the name of the piece ("name").
I changed line 82 to point to the correct ogg file ("name.ogg").
I'm not sure what to do with line 81:
   A) If I change it to "name.m4a" then everything seems to 
compile

Can \barNumberCheck be set to error?

[thorne]

I am just wondering if there is any way to set only \barNumberCheck to
generate an error instead of a warning.

I am using a Makefile to handle a project.  I am using \barNumberCheck
on every bar on every part.  It is convenient to have Lilypond error
any time a bar number check fails so that the render fails and I know
right away.

I tried doing -dwarning-as-error, which works, but then makes the
render fail any time anything generates a warning, which is probably
not something I can have.

Or, is there a better approach in general?

\barNumberCheck is defined in ly/music-functions-init.ly.  It's less
than a dozen lines.  Just copy that definition and replace the call to
ly:input-warning with something else.

Because the whole point of \addlyrics/\lyricsto is to ignore durations
and instead take items one-by-one irrespective of their length?

You can write Lyrics perfectly well without \addlyrics/\lyricsto and
durations both of syllables and skips and other musical material will be

\skip in the Lyrics context is necessary for skipping beats without
creating a melisma (which can be manually created with a single underscore
for each beat in the melisma). I'm not sure why it's insensitive to the
number after it. I have wondered the same thing, but that's the way it
works at the moment. Outside the Lyrics context in normal note entry, it is
sensitive to the number. So, doing something like

\repeat unfold 6 { \skip 4 }

is usually the quickest way to jump more than a couple of beats when you
don't want to attach any lyrics to notes.

On a related, but side, note, I wrote a post a while back about a way
to deal with vertically centering lyrics with the help of a music function.
Anyway, it may be helpful to someone:

Vertically centering a song text.

[Robert Blackstone]

Dear List,

Could anybody help me (a newby) with the following issue:

I am setting a song, vocal line and keyboard, with two sections, the first of 
which has two verses, the second only one, as in the ME, copied, and slightly 
modified, from 
http://www.lilypond.org/doc/v2.18/Documentation/notation/techniques-specific-to-lyrics
  

%%%\score {

\new Staff {
  \new Voice = "melody" {

  \repeat volta 2 { b'4 b b b }
   \repeat volta 2 {a4 a a a }
}
  }
}

\new Lyrics {
  \set associatedVoice = "melody"
  Sec -- ond time words.
}
  >>
  O- ther Ly- rics.

How can I shift the lyrics of the second part vertically so that it is centered 
with respect to the first part, instead of  being in line with "The first time 
words".

Thanks in advance.

It might be sufficient to use the old #' syntax instead of the dots:

\override Fingering #'side-axis = #Y
\override Fingering #'outside-staff-priority = #200

To me the output looks very much like what I think you are looking for.

One one more thing, this method actually does not work. Think like this: the
problem isn't the number of beams for each note (these are correct) but
their overall positions.

E.g., both codes below produce identical scores:

\autochange {
  \override Score.Beam.auto-knee-gap = #3
  \tuplet 5/4 {g''32[e'' g''64 d a,32 gis]}
}

\autochange {
  \override Score.Beam.auto-knee-gap = #3
  \tuplet 5/4 {
g''32[e'' 
\once \set stemLeftBeamCount = #3
\once \set stemRightBeamCount = #4
g''64 
\once \set stemLeftBeamCount = #4
\once \set stemRightBeamCount = #3
d a,32 gis]
  }
}

Re: accidentals for just intonation

[Graham Breed]

From: "N. Andrew Walsh"
To: lilypond-user



If you've been watching the OpenLilyLib repository, you'll see that Urs has
been working on a set of tools for rendering music in just intonation. He
(quite modestly) says that it isn't ready for production, but there are
already some impressive things it can do: for one, the interface allows to
input a fraction and get back a nearest-semitone pitch with a deviation in
cents*automatically*, which is something the commercial programs don't
offer in any way (every composer I know who works with JI just inputs text
entries manually for every note, with no change in, for example, MIDI
output for ability to handle transpositions).


I haven't been watching that ... I don't know what it is.  But it sounds 
similar to my Sagittal support.  Latest code here, works for me but 
something broken on Windows:


https://bitbucket.org/x31eq/microlily

It's possible to turn off the Sagittal accidentals to get output using 
standard accidentals, given essentially the AFMM output.  I don't 
remember if I ever got that working though.  You have to specify the 
staff position as well as the ratio.



I'd like to be able to put these into Lily, and Urs tells me it can be done
by calling a draw function to draw a path. I can relatively easily make up
some paths with Inkscape and save them as SVGs, but is there a better way
to do this? The NR describes (here:
http://lilypond.org/doc/v2.19/Documentation/notation/formatting-text#graphic-notation-inside-markup)
the means to include eps files into a markup, which presumably could be
used to replace the accidental.

There are some potential complicating factors here. First, the accidentals
I use change depending on the prime factorization of the ratio involved:
for example, the ratio 9/8 (a type of whole tone) would comprise two of the
symbol for 3 (because "9/8" is really "(3*3)/8" ), which means that Urs'
interface for JI ratios would need an add-on to do prime factorization of
the ratios (which is also computationally intensive, even for relatively
simple numbers) or a means to encode ratios as lists of primes that are
then calculated to return the value in cents (that is, do the process in
reverse, starting from "(3*3)/8" and getting 9/8, which might be easier to
do).


I've thought about this with respect to the Extended Helmholtz-JI 
notation, for which there are already fonts that would work with my 
system.  Generating accidentals from pitches is problematic, and would 
really mean generating your gamut in advance, with some implied equal 
temperament that doesn't give any ambiguity, and the accidentals would 
disappear if you exceed that gamut.


Another idea is for commands to add the accidental glyphs, and also do 
the correct pitch shift.  I think this was prototyped without the pitch 
shifting (so ignoring MIDI output) before I implemented my Sagittal 
approach.  Where it's problematic to get tuning and display working 
together, you can define separate functions for the "midi" and "score" 
blocks.


Another idea I had, though, is to shove annotations into the list 
describing each note.  (I think the new parser makes this easier than it 
used to be, because each note in a chord is a list.)  You can then run a 
function over the whole music block to strip out the annotations, set 
the pitch, and override the accidental.  You can also apply different 
functions to the same music block in the midi and score blocks to make 
that approach easier.  I did a proof of concept of this, which I can't 
find now, but I haven't followed it up.



The advantage here, though, would be this: one of the interesting things
about just intonation is that there is no theoretical limit to what kinds
of ratios you use. You could theoretically have unique signs for all the
primes you want, and then the draw function could build them on the fly.
The accidentals become modular, scaling to whatever level of complexity the
composer wants. Harry Partch writes music that tops out at the 13th
overtone, but La Monte Young has pieces with primes in the upper 300s.


You can also make a font with a fixed level of complexity, and it will 
be easier to get working for now.  An issue with drawing the glyphs in 
is that you have to be sure to inform LilyPond of the correct amount of 
space to allow for them.


You could also look at the Extended Helmholtz-Ellis JI set, where the 
advantage is that the font already exists.  It's on this page, along 
with some PDFs explaining it:


http://www.marcsabat.com/


So, List: this is, as I said, a somewhat long-term project, but would any
of you be willing to help me learn/do the programming necessary to develop
a system like this? I also have in mind a more general add-on to the OLL
just-intonation library: I'd like to see a set of different .ily files,
each with different sets of accidentals, which a composer could \include
into the score as needed. For example, I could
